Hi Paul, Thank you very much for the response. However, I have tried those options. Adding "stp=on" does not enable STP on the bridges. Each node has a 1Gb Ethernet connection as well as a 10Gb FC connection, I've tried moving the VM migration network to each and the effect is the same. The vdsm disables STP when it writes the ifcfg-em0 or ifcfg-p1p1 files in /etc/sysconfig/networking-scripts. This behavior can been seen when using the standard "brctl show" utilities directly logged into the host. Can the templates that the VDSM uses to write those files be modified, possibly? Thank you!

Hello. I have been trying to figure out an issue for a very long time. That issue relates to the ethernet and 10gb fc links that I have on my cluster being disabled any time a migration occurs.

I believe this is because I need to have STP turned on in order to participate with the switch. However, there does not seem to be any way to tell oVirt to stop turning it off! Very frustrating.

After entering a cronjob that enables stp on all bridges every 1 minute, the migration issue disappears....

Is there any way at all to do without this cronjob and set STP to be ON without having to resort to such a silly solution?

Here are some details about my systems, if you need it.

e.albany, STP is meant to block loops in layer 2. In basic operation, a root bridge is elected which is the root of the tree. This bridge sends, essentially 'hello' messages as multicast packets. The switches then detect the loop in the network and block one of the links to prevent such things as a broadcast storm. There are different flavours of STP but "STP" usually means the hellos are sent over VLAN 1 (or no vlan). Therefore if you have multiple VLANs on links, the hellos are still only sent over VLAN 1 and all VLANs are dealt with that way. Meaning if a link is blocked then all VLANs are blocked on that link, Then came the different flavours, one of which is per-vlan STP. This allows individual VLANs to be blocked and gives more flexibility. After STP has dealt with the blocking, this link blocking will continue until a change in the network is detected. This is detected by the absence of the STP packets or the presence of new STP packets where there shouldnt be. When this happens, STP packets are flooded everywhere to discover the new network topology. Ultimately, the loop will be blocked again. I think that you have two STP versions running in your network and it's causing the issue. An easy test would be to remove the loop manually in the network and leave STP off on the ovirt host. You can view the topology as-per the network STP devices by obtaining info from the devices such as bridge priorities etc. What is your network hardware?

If there is some other configuration that I'm not seeing, please do let me know. I'd love to know more about what the expected configuration is that enables VM migration and how it's "supposed" to be configured. I have 3 hosts - each of these has two bridges. Each of these bridges are named the same for each host. Each bridge has a different IP address that corresponds to the NIC attached to the host on that network. It seemed like the only and obvious choice... On Mon, Aug 19, 2019 at 9:52 PM Curtis E. Combs Jr. <ej.albany@gmail.com> wrote:

Hey Tony!

I only know the basics of Spanning Tree. At the current moment the only way to get migrations to work at all without breaking the whole oVirt cluster is to have it on. After changing it according to Paul's instruction, it works like it has never worked before. Every migration event was successful. Whereas before and even at times with the cronjob (when vdsm set STP to off between cron runs) the link would drop out and oVirt would say that the host was "unresponsive".

It would be too - it wouldn't respond to SSH, ping, arp requests...nothing. I never got a good idea of how long this would be for, but it would, eventually go away and the link would come back online.

I have no access to the hardware. From using tcpdump to get some CDP packets, I do know that it's Cisco switches but the IT team here is completely unresponsive (they literally ignore our tickets) and the co-lo where our servers are hosted won't even pick up the phone for anyone but them....

Unfortunately, this is what I'm going to have to do. The cluster is very functional, though. I created around 15 VMs today and migrated them from host to host without any problem.

Anything else you'd like me to try? This is currently dev, so I can really do anything I want and I can just IPMI reboot the nodes if it causes issues...

Thanks! cecjr

Hey Tony!

I only know the basics of Spanning Tree. At the current moment the only way to get migrations to work at all without breaking the whole oVirt cluster is to have it on. After changing it according to Paul's instruction, it works like it has never worked before. Every migration event was successful. Whereas before and even at times with the cronjob (when vdsm set STP to off between cron runs) the link would drop out and oVirt would say that the host was "unresponsive".

It would be too - it wouldn't respond to SSH, ping, arp requests...nothing. I never got a good idea of how long this would be for, but it would, eventually go away and the link would come back online.

I have no access to the hardware. From using tcpdump to get some CDP packets, I do know that it's Cisco switches but the IT team here is completely unresponsive (they literally ignore our tickets) and the co-lo where our servers are hosted won't even pick up the phone for anyone but them....

Unfortunately, this is what I'm going to have to do. The cluster is very functional, though. I created around 15 VMs today and migrated them from host to host without any problem.

Anything else you'd like me to try? This is currently dev, so I can really do anything I want and I can just IPMI reboot the nodes if it causes issues...

Thanks! cecjr

e.albany,

STP is meant to block loops in layer 2. In basic operation, a root bridge is elected which is the root of the tree. This bridge sends, essentially 'hello' messages as multicast packets. The switches then detect the loop in the network and block one of the links to prevent such things as a broadcast storm.

There are different flavours of STP but "STP" usually means the hellos are sent over VLAN 1 (or no vlan). Therefore if you have multiple VLANs on links, the hellos are still only sent over VLAN 1 and all VLANs are dealt with that way. Meaning if a link is blocked then all VLANs are blocked on that link,

Then came the different flavours, one of which is per-vlan STP. This allows individual VLANs to be blocked and gives more flexibility.

After STP has dealt with the blocking, this link blocking will continue until a change in the network is detected. This is detected by the absence of the STP packets or the presence of new STP packets where there shouldnt be. When this happens, STP packets are flooded everywhere to discover the new network topology. Ultimately, the loop will be blocked again.

I think that you have two STP versions running in your network and it's causing the issue. An easy test would be to remove the loop manually in the network and leave STP off on the ovirt host. You can view the topology as-per the network STP devices by obtaining info from the devices such as bridge priorities etc. What is your network hardware?

Regards,

Tony

Hello. I have been trying to figure out an issue for a very long time. That issue relates to the ethernet and 10gb fc links that I have on my cluster being disabled any time a migration occurs.

I believe this is because I need to have STP turned on in order to participate with the switch. However, there does not seem to be any way to tell oVirt to stop turning it off! Very frustrating.

After entering a cronjob that enables stp on all bridges every 1 minute, the migration issue disappears....

Is there any way at all to do without this cronjob and set STP to be ON without having to resort to such a silly solution?

Here are some details about my systems, if you need it.

Tony, Well, thank you for that, but I'm not using openvswitchs, I'm just using regular bridges. Are you suggesting that I do? From what I can see in the interface they have "(experimental)" marked on them and we'd like to see production with this at some point. None of my ports are trunking between VLANs - they only have one in untagged mode - and there's only 2 VLANs here, one per-port. Thanks again! cecjr On Mon, Aug 19, 2019 at 10:36 PM Tony Pearce <tonyppe@gmail.com> wrote:

With STP off, if the network is detecting a loop then it will have to block a link. With STP on I guess it's allowing the network to remain forwarding and the blocking to occur elsewhere. 👍

Oh, I'm just using the standard Linux bridges. I believe in ovirt nomenclature they're called "legacy bridges". This is not by any real choice but just what is created by default, I believe. In the first link you sent, they are calling them "Linux legacy networking model" - though I only have 2 options when I make a new switch - the default and (it says) "openvswitch (experimental)" On Tue, Aug 20, 2019 at 4:47 AM Tony Pearce <tonyppe@gmail.com> wrote:

No - no recommendations from me to use either. I took it that you were using ovs bridge as I was not aware of another bridge. The only other option I was aware of if what I am using, vlan interfaces and kernel vlan tags. If you could share a link to what you're using, I would be keen to read up on it to know more.

Tony,

Well, thank you for that, but I'm not using openvswitchs, I'm just using regular bridges. Are you suggesting that I do?

From what I can see in the interface they have "(experimental)" marked on them and we'd like to see production with this at some point.

None of my ports are trunking between VLANs - they only have one in untagged mode - and there's only 2 VLANs here, one per-port.

Thanks again! cecjr

A couple of links I found helpful, thought I'd send them over http://therandomsecurityguy.com/openvswitch-cheat-sheet/

https://ovirt.org/develop/release-management/features/network/openvswitch/na...

With STP off, if the network is detecting a loop then it will have to block a link. With STP on I guess it's allowing the network to remain forwarding and the blocking to occur elsewhere. 👍

Hey Tony!

I only know the basics of Spanning Tree. At the current moment the only way to get migrations to work at all without breaking the

whole

...

oVirt cluster is to have it on. After changing it according to Paul's instruction, it works like it has never worked before. Every migration event was successful. Whereas before and even at times with the cronjob (when vdsm set STP to off between cron runs) the link would drop out and oVirt would say that the host was "unresponsive".

It would be too - it wouldn't respond to SSH, ping, arp requests...nothing. I never got a good idea of how long this would be for, but it would, eventually go away and the link would come back online.

I have no access to the hardware. From using tcpdump to get some CDP packets, I do know that it's Cisco switches but the IT team here is completely unresponsive (they literally ignore our tickets) and the co-lo where our servers are hosted won't even pick up the phone for anyone but them....

Unfortunately, this is what I'm going to have to do. The cluster is very functional, though. I created around 15 VMs today and migrated them from host to host without any problem.

Anything else you'd like me to try? This is currently dev, so I can really do anything I want and I can just IPMI reboot the nodes if it causes issues...

Thanks! cecjr

Hello. I have been trying to figure out an issue for a very long time. That issue relates to the ethernet and 10gb fc links that I have on my cluster being disabled any time a migration occurs.

I believe this is because I need to have STP turned on in order to participate with the switch. However, there does not seem to be any way to tell oVirt to stop turning it off! Very frustrating.

After entering a cronjob that enables stp on all bridges every 1 minute, the migration issue disappears....

Is there any way at all to do without this cronjob and set STP to be ON without having to resort to such a silly solution?

Vdsm exposes a per bridge STP knob that you can use for this. By default it is set to false, which is probably why you had to use this shenanigan.

You can, for instance:

Seems like the STP options are so common and necessary that it would be a priority over seldom-used bridge_opts. I know what STP is and I'm not even a networking guy - never even heard of half of the bridge_opts that have switches in the UI.

Anyway. I wanted to try the openvswitches, so I reinstalled all of my nodes and used "openvswitch (Technology Preview)" as the engine-setup option for the first host. I made a new Cluster for my nodes, added them all to the new cluster, created a new "logical network" for the internal network and attached it to the internal network ports.

Now, when I go to create a new VM, I don't even have either the ovirtmgmt switch OR the internal switch as an option. The drop-down is empy as if I don't have any vnic-profiles.

openvswitch clusters are limited to ovn networks. You can create one like described in https://www.ovirt.org/documentation/admin-guide/chap-External_Providers.html...

Hello. I have been trying to figure out an issue for a very long

time.

...

...

That issue relates to the ethernet and 10gb fc links that I have on my cluster being disabled any time a migration occurs.

I believe this is because I need to have STP turned on in order to participate with the switch. However, there does not seem to be any way to tell oVirt to stop turning it off! Very frustrating.

After entering a cronjob that enables stp on all bridges every 1 minute, the migration issue disappears....

Is there any way at all to do without this cronjob and set STP to be ON without having to resort to such a silly solution?

Vdsm exposes a per bridge STP knob that you can use for this. By default it is set to false, which is probably why you had to use this shenanigan.

You can, for instance:

Sorry to dead bump this, but I'm beginning to suspect that maybe it's not STP that's the problem. 2 of my hosts just went down when a few VMs tried to migrate. Do any of you have any idea what might be going on here? I don't even know where to start. I'm going to include the dmesg in case it helps. This happens on both of the hosts whenever any migration attempts to start.

Seems like the STP options are so common and necessary that it would be a priority over seldom-used bridge_opts. I know what STP is and I'm not even a networking guy - never even heard of half of the bridge_opts that have switches in the UI.

Anyway. I wanted to try the openvswitches, so I reinstalled all of my nodes and used "openvswitch (Technology Preview)" as the engine-setup option for the first host. I made a new Cluster for my nodes, added them all to the new cluster, created a new "logical network" for the internal network and attached it to the internal network ports.

Now, when I go to create a new VM, I don't even have either the ovirtmgmt switch OR the internal switch as an option. The drop-down is empy as if I don't have any vnic-profiles.

openvswitch clusters are limited to ovn networks. You can create one like described in https://www.ovirt.org/documentation/admin-guide/chap-External_Providers.html...

Vdsm exposes a per bridge STP knob that you can use for this. By default it is set to false, which is probably why you had to use this shenanigan.

You can, for instance:

I don't think this STP parameter is exposed via engine UI; @Dominik Holler , could you confirm ? What are our plans for it ?

STP is only available via REST-API, see http://ovirt.github.io/ovirt-engine-api-model/4.3/#types/network please find an example how to enable STP in https://gist.github.com/dominikholler/4e70c9ef9929d93b6807f56d43a70b95

We have no plans to add STP to the web ui, but new feature requests are always welcome on https://bugzilla.redhat.com/enter_bug.cgi?product=ovirt-engine

Sorry to dead bump this, but I'm beginning to suspect that maybe it's not STP that's the problem.

2 of my hosts just went down when a few VMs tried to migrate.

Do any of you have any idea what might be going on here? I don't even know where to start. I'm going to include the dmesg in case it helps. This happens on both of the hosts whenever any migration attempts to start.

Seems like the STP options are so common and necessary that it would be a priority over seldom-used bridge_opts. I know what STP is and I'm not even a networking guy - never even heard of half of the bridge_opts that have switches in the UI.

Anyway. I wanted to try the openvswitches, so I reinstalled all of my nodes and used "openvswitch (Technology Preview)" as the engine-setup option for the first host. I made a new Cluster for my nodes, added them all to the new cluster, created a new "logical network" for the internal network and attached it to the internal network ports.

Now, when I go to create a new VM, I don't even have either the ovirtmgmt switch OR the internal switch as an option. The drop-down is empy as if I don't have any vnic-profiles.

openvswitch clusters are limited to ovn networks. You can create one like described in https://www.ovirt.org/documentation/admin-guide/chap-External_Providers.html...

Hi Dominik, would you mind sharing the use case for stp via API Only? I am keen to know this. Thanks

Also, if it helps, the hosts will sit there, quietly, for hours or days before anything happens. They're up and working just fine. But then, when I manually migrate a VM from one host to another, they become completely inaccessible.

Can you share some details about your storage? Maybe there is a feature used during live migration, which triggers the issue.

These are vanilla-as-possible CentOS7 nodes. Very basic ovirt install and configuration.

Hey Dominik,

Thanks for helping. I really want to try to use ovirt.

When these events happen, I cannot even SSH to the nodes due to the link being down. After a little while, the hosts come back...

Is you storage connected via NFS? Can you manually access the storage on the host?

Sorry to dead bump this, but I'm beginning to suspect that maybe it's not STP that's the problem.

2 of my hosts just went down when a few VMs tried to migrate.

Do any of you have any idea what might be going on here? I don't even know where to start. I'm going to include the dmesg in case it helps. This happens on both of the hosts whenever any migration attempts to

start.

openvswitch clusters are limited to ovn networks. You can create one like described in

Sure! Right now, I only have a 500gb partition on each node shared over NFS, added as storage domains. This is on each node - so, currently 3.

How can the storage cause a node to drop out?

Thanks, I got it. All three links go down on load, which causes NFS to fail. Can you check in the switch port configuration if there is some kind of Ethernet flow control enabled? Can you try to modify the behavior by changing the settings of your host interfaces, e.g. ethtool -A em1 autoneg off rx off tx off or ethtool -A em1 autoneg on rx on tx on ?

Also, if it helps, the hosts will sit there, quietly, for hours or days before anything happens. They're up and working just fine. But then, when I manually migrate a VM from one host to another, they become completely inaccessible.

Can you share some details about your storage? Maybe there is a feature used during live migration, which triggers the issue.

These are vanilla-as-possible CentOS7 nodes. Very basic ovirt install and configuration.

Hey Dominik,

Thanks for helping. I really want to try to use ovirt.

When these events happen, I cannot even SSH to the nodes due to the link being down. After a little while, the hosts come back...

Is you storage connected via NFS? Can you manually access the storage on the host?

not STP that's the problem.

2 of my hosts just went down when a few VMs tried to migrate.

Do any of you have any idea what might be going on here? I don't even know where to start. I'm going to include the dmesg in case it helps. This happens on both of the hosts whenever any migration attempts to start.

Unfortunately, I can't check on the switch. Trust me, I've tried. These servers are in a Co-Lo and I've put 5 tickets in asking about the port configuration. They just get ignored - but that's par for the coarse for IT here. Only about 2 out of 10 of our tickets get any response and usually the response doesn't help. Then the system they use auto-closes the ticket. That was why I was suspecting STP before.

I can do ethtool. I do have root on these servers, though. Are you trying to get me to turn off link-speed auto-negotiation? Would you like me to try that?

It is just a suspicion, that the reason is pause frames. Let's start on a NIC which is not used for ovirtmgmt, I guess em1. Does 'ethtool -S em1 | grep pause' show something? Does 'ethtool em1 | grep pause' indicates support for pause? The current config is shown by 'ethtool -a em1'. '-A autoneg' "Specifies whether pause autonegotiation should be enabled." according to ethtool doc. Assuming flow control is enabled by default, I would try to disable it via 'ethtool -A em1 autoneg off rx off tx off' and check if it is applied via 'ethtool -a em1' and check if the behavior under load changes.

Sure! Right now, I only have a 500gb partition on each node shared over

NFS, added as storage domains. This is on each node - so, currently 3.

...

How can the storage cause a node to drop out?

Thanks, I got it. All three links go down on load, which causes NFS to fail.

Can you check in the switch port configuration if there is some kind of Ethernet flow control enabled? Can you try to modify the behavior by changing the settings of your host interfaces, e.g.

ethtool -A em1 autoneg off rx off tx off

So, I went ahead and used your ethtool commands to disable pause frames on both interfaces of each server. I then, chose a few VMs to migrate around at random.

swm-02 and swm-03 both went out again. Unreachable. Can't ping, can't ssh, and the SSH session that I had open was unresponsive.

Any other ideas?

Sorry, no. Looks like two different NICs with different drivers and frimware goes down together. This is a strong indication that the root cause is related to the switch. Maybe you can get some information about the switch config by 'lldptool get-tlv -n -i em1'

Unfortunately, I can't check on the switch. Trust me, I've tried. These servers are in a Co-Lo and I've put 5 tickets in asking about the port configuration. They just get ignored - but that's par for the coarse for IT here. Only about 2 out of 10 of our tickets get any response and usually the response doesn't help. Then the system they use auto-closes the ticket. That was why I was suspecting STP before.

I can do ethtool. I do have root on these servers, though. Are you trying to get me to turn off link-speed auto-negotiation? Would you like me to try that?

It is just a suspicion, that the reason is pause frames. Let's start on a NIC which is not used for ovirtmgmt, I guess em1. Does 'ethtool -S em1 | grep pause' show something? Does 'ethtool em1 | grep pause' indicates support for pause? The current config is shown by 'ethtool -a em1'. '-A autoneg' "Specifies whether pause autonegotiation should be enabled." according to ethtool doc. Assuming flow control is enabled by default, I would try to disable it via 'ethtool -A em1 autoneg off rx off tx off' and check if it is applied via 'ethtool -a em1' and check if the behavior under load changes.

Sure! Right now, I only have a 500gb partition on each node shared

over NFS, added as storage domains. This is on each node - so, currently 3.

...

How can the storage cause a node to drop out?

Thanks, I got it. All three links go down on load, which causes NFS to fail.

Can you check in the switch port configuration if there is some kind of Ethernet flow control enabled? Can you try to modify the behavior by changing the settings of your host interfaces, e.g.

ethtool -A em1 autoneg off rx off tx off

or ethtool -A em1 autoneg on rx on tx on ?

It took a while for my servers to come back on the network this time. I think it's due to ovirt continuing to try to migrate the VMs around like I requested. The 3 servers' names are "swm-01, swm-02 and swm-03". Eventually (about 2-3 minutes ago) they all came back online. So I disabled and stopped the lldpad service. Nope. Started some more migrations and swm-02 and swm-03 disappeared again. No ping, SSH hung, same as before - almost as soon as the migration started. If you wall have any ideas what switch-level setting might be enabled, let me know, cause I'm stumped. I can add it to the ticket that's requesting the port configurations. I've already added the port numbers and switch name that I got from CDP. Thanks again, I really appreciate the help! cecjr On Fri, Aug 23, 2019 at 3:28 PM Dominik Holler <dholler@redhat.com> wrote:

This little cluster isn't in production or anything like that yet.

So, I went ahead and used your ethtool commands to disable pause frames on both interfaces of each server. I then, chose a few VMs to migrate around at random.

swm-02 and swm-03 both went out again. Unreachable. Can't ping, can't ssh, and the SSH session that I had open was unresponsive.

Any other ideas?

Sorry, no. Looks like two different NICs with different drivers and frimware goes down together. This is a strong indication that the root cause is related to the switch. Maybe you can get some information about the switch config by 'lldptool get-tlv -n -i em1'

Another guess: After the optional 'lldptool get-tlv -n -i em1' 'systemctl stop lldpad' another try to migrate.

Unfortunately, I can't check on the switch. Trust me, I've tried. These servers are in a Co-Lo and I've put 5 tickets in asking about the port configuration. They just get ignored - but that's par for the coarse for IT here. Only about 2 out of 10 of our tickets get any response and usually the response doesn't help. Then the system they use auto-closes the ticket. That was why I was suspecting STP before.

I can do ethtool. I do have root on these servers, though. Are you trying to get me to turn off link-speed auto-negotiation? Would you like me to try that?

It is just a suspicion, that the reason is pause frames. Let's start on a NIC which is not used for ovirtmgmt, I guess em1. Does 'ethtool -S em1 | grep pause' show something? Does 'ethtool em1 | grep pause' indicates support for pause? The current config is shown by 'ethtool -a em1'. '-A autoneg' "Specifies whether pause autonegotiation should be enabled." according to ethtool doc. Assuming flow control is enabled by default, I would try to disable it via 'ethtool -A em1 autoneg off rx off tx off' and check if it is applied via 'ethtool -a em1' and check if the behavior under load changes.

Thanks, I got it. All three links go down on load, which causes NFS to fail.

Can you check in the switch port configuration if there is some kind of Ethernet flow control enabled? Can you try to modify the behavior by changing the settings of your host interfaces, e.g.

ethtool -A em1 autoneg off rx off tx off

or ethtool -A em1 autoneg on rx on tx on ?

Is the nic to the network staying up or going down for a period?

Which nic? The one on the pserver or the virtual machine? For clarity, I've only ever referred to the one on the pserver. I can't even reach the VM when the pserver becomes unresponse during a migration, so I can't reach the console for the VM even if the proxy is not involved in the link down event.

I'm just thinking, if the network has been configured to block unknown unicast traffic, I think the VM would need to send a layer 2 frame to the network before the network would send any frames to that switch port destined for the VM.

Please, any and all ideas are welcome, and I'll try all of them. I love this product, and I want to see it working well. I don't know that it's configured to block unknown unicast traffic, I don't know that it isn't - NOC doesn't tell me squat. Just inductively, I can, maybe, think that if the switch somehow recognizes a mac on more than one port, it shuts them both down - but that's just speculation on a good day; I have no evidence of that. I can test again to be sure, but I believe that both the sending and receiving migration server go down during this event. Even more curious is that it happens over the 10g FC link as well as the 1g copper, TP port. Would it be a good test of your theory to set up an indefinite ping on a VM when I can reach it and then migrate it to see if the outage happens with the VM migrating?

After migration, could you use the VM console to send a packet and then see if you can SSH in? Is the default Gateway for the VM on the network side? A ping to the Gateway should be good enough in that case.

During times when it's up after it's thrown its little fit, I can change the migration network to either the 1g or 10g networks. So I could set up a ping and let it go like I was saying before. It's worth a shot....

It took a while for my servers to come back on the network this time. I think it's due to ovirt continuing to try to migrate the VMs around like I requested. The 3 servers' names are "swm-01, swm-02 and swm-03". Eventually (about 2-3 minutes ago) they all came back online.

So I disabled and stopped the lldpad service.

Nope. Started some more migrations and swm-02 and swm-03 disappeared again. No ping, SSH hung, same as before - almost as soon as the migration started.

If you wall have any ideas what switch-level setting might be enabled, let me know, cause I'm stumped. I can add it to the ticket that's requesting the port configurations. I've already added the port numbers and switch name that I got from CDP.

Thanks again, I really appreciate the help! cecjr

This little cluster isn't in production or anything like that yet.

So, I went ahead and used your ethtool commands to disable pause frames on both interfaces of each server. I then, chose a few VMs to migrate around at random.

swm-02 and swm-03 both went out again. Unreachable. Can't ping, can't ssh, and the SSH session that I had open was unresponsive.

Any other ideas?

Sorry, no. Looks like two different NICs with different drivers and frimware goes down together. This is a strong indication that the root cause is related to the switch. Maybe you can get some information about the switch config by 'lldptool get-tlv -n -i em1'

Another guess: After the optional 'lldptool get-tlv -n -i em1' 'systemctl stop lldpad' another try to migrate.

It is just a suspicion, that the reason is pause frames. Let's start on a NIC which is not used for ovirtmgmt, I guess em1. Does 'ethtool -S em1 | grep pause' show something? Does 'ethtool em1 | grep pause' indicates support for pause? The current config is shown by 'ethtool -a em1'. '-A autoneg' "Specifies whether pause autonegotiation should be enabled." according to ethtool doc. Assuming flow control is enabled by default, I would try to disable it via 'ethtool -A em1 autoneg off rx off tx off' and check if it is applied via 'ethtool -a em1' and check if the behavior under load changes.
