Hi Everyone,
Okay, I'm again having problems with getting basic networking setup
with oVirt 4.1 Here is my situation. I have two servers I want to use
to create an oVirt cluster, with two different networks. My "public"
network is a 1G link on device em1 connected to my Internet feed, and my
"storage" network is a 10G link connected on device p5p1 to my file
server. Since I need to connect to my storage network in order to do
the install, I selected p5p1 has the ovirtmgmt interface when installing
the hosted engine. That worked fine, I got everything installed, so I
used some ssh-proxy magic to connect to the web console and completed
the install (setup a Storage domain and create a new network vmNet for
VM networking and added em1 to it.)
The problem was that when I added a second network device to the
HostedEngine VM (so that I can connect to it from my public network) it
would intermittently go down. I did some digging and found some IPV6
errors in the dmesg (IPv6: eth1: IPv6 duplicate address
2001:410:e000:902:21a:4aff:fe16:151 detected!) so I disabled IPv6 on
both eth0 and eth1 in the HostedEngine and rebooted it. The problem is
that when I restarted the VM, the eth1 device was missing.
So, my question is: Can I add a second NIC to the HostedEngine VM and
make it stick, or will it be deleted whenever the engine VM is
restarted? Is there a better way to do what I'm trying to do, ie,
should I setup ovirtmgmt on the public em1 interface, and then create
the "storage" network after the fact for connecting to the datastores
and such. Is that even possible, or required? I was thinking that it
would be better for migrations and other management functions to happen
on the faster 10G network, but if the HostedEngine doesn't need to be
able to connect to the storage network maybe it's not worth the effort?
Eventually I want to setup LACP on the storage network, but I had to
wipe the servers and reinstall from scratch the last time I tried to set
that up. I was thinking that it was because I setup the bonding before
installing oVirt, so I didn't do that this time.
Here are my /etc/sysconfig/network-scripts/ifcfg-* files in case I
did something wrong there (I'm more familiar with Debian/Ubuntu network
setup than CentOS)

Hello Charles,
First, can you give us more information regarding the duplicated IPv6
addresses? Since you are going to reinstall the hosted engine, could you
make sure that NetworkManager is disabled before adding the second vNIC
(and perhaps even disable IPv6 and reboot as well, so we have a solid base
and see what makes the difference)?
What kind of documentation did you follow to install the hosted engine? Was
it this page? https://www.ovirt.org/documentation/how-to/hosted-engine/ If
so, could you file a bug against VDSM networking and attach
/var/log/vdsm/vdsm.log and supervdsm.log, and make sure they include the
time period from adding the second vNIC to rebooting?
Second, even the vNIC going missing after reboot looks like a bug to me.
Even though eth1 does not exist in the VM, can you see it defined for the
VM in the engine web GUI?
The steps you took to install the hosted engine with regards to networking
look good to me, but I believe Sandro (CC'ed) would be able to give more
advice.
Sandro, since we want to configure bonding, would you recommend to install
the engine physically first, move it to a VM, according to the following
method, and only then reconfigure networking?

When you change something in the HE Vm using the web ui, it has to be saved
also on the OVF_STORE to make it permanent for further reboot.
Martin can you please elaborate here?

Then when the network dropped I started getting these:

The network on eth1 would go down for a few seconds then come back up,
but networking stays solid on eth0. I disabled NetworkManager on the HE
VM as well to see if that makes a difference. I also disabled IPv6 with
sysctl to see if that helps. I'll install a Ubuntu VM on the cluster
later today and see if it has a similar issue.
What kind of documentation did you follow to install the hosted
engine? Was it this page?
https://www.ovirt.org/documentation/how-to/hosted-engine/
<https://www.ovirt.org/documentation/how-to/hosted-engine/> If so,
could you file a bug against VDSM networking and attach
/var/log/vdsm/vdsm.log and supervdsm.log, and make sure they
include the time period from adding the second vNIC to rebooting?
Second, even the vNIC going missing after reboot looks like a bug
to me. Even though eth1 does not exist in the VM, can you see it
defined for the VM in the engine web GUI?
If the HE vm configuration wasn't flushed to the OVF_STORE yet, it
make sense it disappeared on restart.
The docs I used were
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/...
which someone on the list pointed me to last week as being more
up-to-date than what was on the website (the docs on the website don't
seem to mention that you need to put the HE on it's own datastore and
look to be more geared towards bare-metal engine rather than the VM self
hosted option.)
When I went back into the GUI and looked at the hosted engine config the
second NIC was listed there, but it wasn't showing up in lspci on the
VM. I removed the NIC in the GUI and re-added it, and the device
appeared again on the VM. What is the proper way to "save" the state of
the VM so that the OVF_STORE gets updated? When I do anything on the HE
VM that I want to test I just type "reboot", but that powers down the
VM. I then login to my host and run "hosted-engine --vm-start" which
restarts it, but of course the last time I did that it restarted without
the second NIC.
The steps you took to install the hosted engine with regards to
networking look good to me, but I believe Sandro (CC'ed) would be
able to give more advice.
Sandro, since we want to configure bonding, would you recommend to
install the engine physically first, move it to a VM, according to
the following method, and only then reconfigure networking?

The network on eth1 would go down for a few seconds then come back

on the HE VM as well to see if that makes a difference. I also
disabled IPv6 with sysctl to see if that helps. I'll install a
Ubuntu VM on the cluster later today and see if it has a similar
issue.<br>

<br>
Okay, I'm again having problems with getting
basic networking setup with oVirt 4.1 Here is
my situation. I have two servers I want to use
to create an oVirt cluster, with two different
networks. My "public" network is a 1G link on
device em1 connected to my Internet feed, and my
"storage" network is a 10G link connected on
device p5p1 to my file server. Since I need to
connect to my storage network in order to do the
install, I selected p5p1 has the ovirtmgmt
interface when installing the hosted engine.
That worked fine, I got everything installed, so
I used some ssh-proxy magic to connect to the
web console and completed the install (setup a
Storage domain and create a new network vmNet
for VM networking and added em1 to it.)<br>
<br>
The problem was that when I added a second
network device to the HostedEngine VM (so that I
can connect to it from my public network) it
would intermittently go down. I did some
digging and found some IPV6 errors in the dmesg
(IPv6: eth1: IPv6 duplicate address
2001:410:e000:902:21a:4aff:fe1<wbr>6:151
detected!) so I disabled IPv6 on both eth0 and
eth1 in the HostedEngine and rebooted it. The
problem is that when I restarted the VM, the
eth1 device was missing.<br>
<br>
So, my question is: Can I add a second NIC to
the HostedEngine VM and make it stick, or will
it be deleted whenever the engine VM is
restarted? </blockquote>

<div>When you change something in the HE Vm using the web

ovirtmgmt on the public em1 interface, and then

even possible, or required? I was thinking that
it would be better for migrations and other
management functions to happen on the faster 10G
network, but if the HostedEngine doesn't need to
be able to connect to the storage network maybe
it's not worth the effort?<br>
<br>
Eventually I want to setup LACP on the storage
network, but I had to wipe the servers and
reinstall from scratch the last time I tried to
set that up. I was thinking that it was because
I setup the bonding before installing oVirt, so
I didn't do that this time.<br>

Hi Everyone,
Just an update, I installed a new Ubuntu guest VM and it was doing
the same thing regarding the network going down, then I disabled IPv6
and it's been fine for the past 10-15 minutes. So the issue seems to be
IPv6 related, and I don't need IPv6 so I can just turn it off. The eth1
NIC disappearing is still worrisome though.

I disabled NetworkManager on the hosts (systemctl disable
NetworkManager ; service NetworkManager stop) before doing the oVirt
setup and rebooted to make sure that it didn't come back up. Or are
you referring to on the hosted engine VM? I just removed and re-added
the eth1 NIC in the hosted engine, and this is what showed up in dmesg:

<p>Hi Everyone,</p>
<p> Just an update, I installed a new Ubuntu guest VM and it was
doing the same thing regarding the network going down, then I
disabled IPv6 and it's been fine for the past 10-15 minutes. So
the issue seems to be IPv6 related, and I don't need IPv6 so I can
just turn it off. The eth1 NIC disappearing is still worrisome
though.<br>

<div>Hello Charles,<br>
<br>
</div>
<div>First, can you give us more information regarding
the duplicated IPv6 addresses? Since you are going
to reinstall the hosted engine, could you make sure
that NetworkManager is disabled before adding the
second vNIC (and perhaps even disable IPv6 and
reboot as well, so we have a solid base and see what
makes the difference)?<br>

I disabled NetworkManager on the hosts (systemctl disable
NetworkManager ; service NetworkManager stop) before doing the
oVirt setup and rebooted to make sure that it didn't come back
up. Or are you referring to on the hosted engine VM? I just
removed and re-added the eth1 NIC in the hosted engine, and this
is what showed up in dmesg:<br>

The network on eth1 would go down for a few seconds then come back
up, but networking stays solid on eth0. I disabled NetworkManager
on the HE VM as well to see if that makes a difference. I also
disabled IPv6 with sysctl to see if that helps. I'll install a
Ubuntu VM on the cluster later today and see if it has a similar
issue.<br>

The docs I used were
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="https://access.redhat.com/documentation/en-us/red_hat_virtuali...
which someone on the list pointed me to last week as being more
up-to-date than what was on the website (the docs on the website
don't seem to mention that you need to put the HE on it's own
datastore and look to be more geared towards bare-metal engine
rather than the VM self hosted option.)<br>
<br>
When I went back into the GUI and looked at the hosted engine
config the second NIC was listed there, but it wasn't showing up
in lspci on the VM. I removed the NIC in the GUI and re-added it,
and the device appeared again on the VM. What is the proper way
to "save" the state of the VM so that the OVF_STORE gets updated?
When I do anything on the HE VM that I want to test I just type
"reboot", but that powers down the VM. I then login to my host
and run "hosted-engine --vm-start" which restarts it, but of
course the last time I did that it restarted without the second
NIC.<br>

<br>
Okay, I'm again having problems with getting
basic networking setup with oVirt 4.1 Here is
my situation. I have two servers I want to
use to create an oVirt cluster, with two
different networks. My "public" network is a
1G link on device em1 connected to my Internet
feed, and my "storage" network is a 10G link
connected on device p5p1 to my file server.
Since I need to connect to my storage network
in order to do the install, I selected p5p1
has the ovirtmgmt interface when installing
the hosted engine. That worked fine, I got
everything installed, so I used some ssh-proxy
magic to connect to the web console and
completed the install (setup a Storage domain
and create a new network vmNet for VM
networking and added em1 to it.)<br>
<br>
The problem was that when I added a second
network device to the HostedEngine VM (so that
I can connect to it from my public network) it
would intermittently go down. I did some
digging and found some IPV6 errors in the
dmesg (IPv6: eth1: IPv6 duplicate address
2001:410:e000:902:21a:4aff:fe1<wbr>6:151
detected!) so I disabled IPv6 on both eth0 and
eth1 in the HostedEngine and rebooted it. The
problem is that when I restarted the VM, the
eth1 device was missing.<br>
<br>
So, my question is: Can I add a second NIC
to the HostedEngine VM and make it stick, or
will it be deleted whenever the engine VM is
restarted? </blockquote>

<div>When you change something in the HE Vm using the web

was thinking that it would be better for
migrations and other management functions to

Eventually I want to setup LACP on the

Ah, spoke to soon. 30 seconds later the network went down with IPv6
disabled. So it does appear to be a host forwarding problem, not a VM
problem. I have an oVirt 4.0 cluster on the same network that doesn't
have these issues, so it must be a configuration issue somewhere. Here
is a dump of my ip config on the host:

<p>Ah, spoke to soon. 30 seconds later the network went down with
IPv6 disabled. So it does appear to be a host forwarding problem,
not a VM problem. I have an oVirt 4.0 cluster on the same network
that doesn't have these issues, so it must be a configuration
issue somewhere. Here is a dump of my ip config on the host:</p>

<div>First, can you give us more information
regarding the duplicated IPv6 addresses? Since you

you make sure that NetworkManager is disabled

I disabled NetworkManager on the hosts (systemctl disable
NetworkManager ; service NetworkManager stop) before doing the
oVirt setup and rebooted to make sure that it didn't come back
up. Or are you referring to on the hosted engine VM? I just
removed and re-added the eth1 NIC in the hosted engine, and this
is what showed up in dmesg:<br>

The network on eth1 would go down for a few seconds then come
back up, but networking stays solid on eth0. I disabled
NetworkManager on the HE VM as well to see if that makes a
difference. I also disabled IPv6 with sysctl to see if that
helps. I'll install a Ubuntu VM on the cluster later today and
see if it has a similar issue.<br>

The docs I used were <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="https://access.redhat.com/documentation/en-us/red_hat_virtuali...
which someone on the list pointed me to last week as being more
up-to-date than what was on the website (the docs on the website
don't seem to mention that you need to put the HE on it's own
datastore and look to be more geared towards bare-metal engine
rather than the VM self hosted option.)<br>
<br>
When I went back into the GUI and looked at the hosted engine
config the second NIC was listed there, but it wasn't showing up
in lspci on the VM. I removed the NIC in the GUI and re-added
it, and the device appeared again on the VM. What is the proper
way to "save" the state of the VM so that the OVF_STORE gets
updated? When I do anything on the HE VM that I want to test I
just type "reboot", but that powers down the VM. I then login
to my host and run "hosted-engine --vm-start" which restarts it,
but of course the last time I did that it restarted without the
second NIC.<br>

<br>
Okay, I'm again having problems with
getting basic networking setup with oVirt
4.1 Here is my situation. I have two
servers I want to use to create an oVirt
cluster, with two different networks. My
"public" network is a 1G link on device em1
connected to my Internet feed, and my
"storage" network is a 10G link connected on
device p5p1 to my file server. Since I need
to connect to my storage network in order to
do the install, I selected p5p1 has the
ovirtmgmt interface when installing the
hosted engine. That worked fine, I got
everything installed, so I used some
ssh-proxy magic to connect to the web
console and completed the install (setup a
Storage domain and create a new network
vmNet for VM networking and added em1 to
it.)<br>
<br>
The problem was that when I added a second
network device to the HostedEngine VM (so
that I can connect to it from my public
network) it would intermittently go down. I
did some digging and found some IPV6 errors
in the dmesg (IPv6: eth1: IPv6 duplicate
address 2001:410:e000:902:21a:4aff:fe1<wbr>6:151
detected!) so I disabled IPv6 on both eth0
and eth1 in the HostedEngine and rebooted
it. The problem is that when I restarted
the VM, the eth1 device was missing.<br>
<br>
So, my question is: Can I add a second NIC
to the HostedEngine VM and make it stick, or
will it be deleted whenever the engine VM is
restarted? </blockquote>

<div><br>
</div>
<div>When you change something in the HE Vm using the
web ui, it has to be saved also on the OVF_STORE to
make it permanent for further reboot.</div>
<div>Martin can you please elaborate here?</div>

better way to do what I'm trying to do, ie,
should I setup ovirtmgmt on the public em1
interface, and then create the "storage"
network after the fact for connecting to the
datastores and such. Is that even possible,
or required? I was thinking that it would
be better for migrations and other
management functions to happen on the faster
10G network, but if the HostedEngine doesn't
need to be able to connect to the storage
network maybe it's not worth the effort?<br>
<br>
Eventually I want to setup LACP on the
storage network, but I had to wipe the
servers and reinstall from scratch the last
time I tried to set that up. I was thinking
that it was because I setup the bonding
before installing oVirt, so I didn't do that
this time.<br>

Ah, spoke to soon. 30 seconds later the network went down with IPv6
disabled. So it does appear to be a host forwarding problem, not a VM
problem. I have an oVirt 4.0 cluster on the same network that doesn't
have these issues, so it must be a configuration issue somewhere.
Here is a dump of my ip config on the host:
