Yes, thanks)

Engine complains about the bootproto , he is expecting dhcp, but you configured it manually with static.
Was it dhcp before the upgrade?

There is an option to change it back to dhcp, restart network service and this should be fixed. But i don't think that this is what you looking for as you may loose connectivity for few seconds.
I don't think there is another option to sync the network while a running VM using it, at least not that i'm aware of.

Maybe Dan or Yevgeny will have some insight.
 
Just to be clear, you upgraded both engine and vdsm?
I'm a bit confused from your ifcfg files, you said you created the ifcfg-ovirtmgmt manually after the upgrade, but it was generated by an older vdsm version  4.17.23.2-0.el7.centos, and the physical interface generated with a newer vdsm version 4.19.10.1-1.el7.centos.

I don't think we need the whole /vdsm , only the relevant vdsm log from the upgrade time, can you locate it?
and the supervdsm.log as well.

Thanks,

The version that I upgraded too:
oVirt Engine Version: 4.1.1.8-1.el7.centos

I dont recall the version I was on prior to the upgrade but I am sure it was at least v4.

Shall I just tar everying thing in /var/log/vdsm/  ?

Ok,

What is the exact property reported in the tooltip which is out of sync? it should be there.
It is possible to add this property to the ifcfg-ovirtmgmt file and then 'refresh caps' it may work.
As you created the ifcfg manually after the upgrade, maybe you missed a property, which engine expect to see.

- About the upgrade, it is very bad that the ifcfg-ovirtmgmt file has gone.
What are the versions involved here?
Maybe i can try and reproduce it, to insure we don't have bug here.

Can you provide us vdsm logs from the upgrade time?

Dan, Yevgeny, do you have any idea maybe?

Thanks,

Michael,

The tooltip says:
"host nework's configurations differ from DC"
It is possible that the out-of-sync is the reason for the network issue.
It's a real problem that your ifcfg-ovirtmgmt file was missing after upgrade, could it be that it wasn't persisted and saved on the host before running the upgrade?
I wish I had an answer for this.  It is possible?  The firs line is commented and says:
"# Generated by VDSM version 4.17.23.2-0.el7.centos"


- I tried refreshing capabilites, no change.
- It is possible to check or uncheck it.
-  this is not an option.
I mentioned in my first email that this is a single host that is used for development only.  That is why I ask if there is a why to perform the networksync via CLI, or perhaps manually?

- Can you please try to press the 'refresh caps' button?
- Does the 'save Network Configuration' button grayed out or it's possible to press it?
- Another option is to migrate the hosted-engine VM to another host in the cluster and then sync the network on the host.(as you can't sync a network being used by a running VM).

Hi Michael, thanks for the suggestion.  When I use the GUI I get the error

"Error while executing action HostSetupNetworks: Network is currently being used"

The network is in use by the engine, that is why I asked if there is a was to sync via the CLI.

This problem happened after I did the latest upgraded and the host had lost the /etc/sysconfig/netowrk-scripts/ifcfg-ovirtmgmt file.  So I recreated the file and I thought alll was well except I cannot open a from outside of the host and engine network (10.3.1.0/24).

source 10.3.5.0/24 cannot open console on at the destination 10.3.1.0/24.  The error I get is:

"Unable to connect to the graphic server /tmp/mozilla_digger0/console.vv
could not connect to 10.3.1.7:Socket I/O timed out"

I have already verified that the iptables rules are open and I have verified that ASA that is between the network is not blocking by doing both a packet-tracer and reviewing the logs.

I think the problem is this "out-of-sync" network issue?

Hello Alex,

- Have you tried to sync it using the 'Sync All Networks' button in the UI? 
It's located under 'Hosts' main tab > select the host > 'Network Interfaces' sub tab > 'Sync All Networks' button.

- Can you please go to the 'Setup Host Networks' dialog(located under the same path^^) and hoover on top of ovirtmgmt network? a tooltip should pop-up and it should let you know what is the reason that the network is being out-of-sync. Engine probably complaining about a difference between the configuration on the host and the DC.
- How did you end up with this situation? what happened before the network become out-of-sync? did it happened after the hosted-engine deploy was done?

Best regards,

Hi,

I upgraded to the latest version (users@ovirt.org) a few weeks ago and ever since then I cannot open a console unless I am on the local network (10.3.1.0/24).  I think it is related to the Ovirtmgmt interface being "out-of-sync".

If I try to fix it in the gui, I get an error:

"Error while executing action HostSetupNetworks: Network is currently being used"

This is because the hosted engine in on the ovirtmgmt network.

Is there a way I can fix this via cli?  This is a single host with a hosted engine.  I use it for development only.

Thank you.
