Hi Everybody,
I had a strange incident today.. One of my nodes restarted (Still busy
investigating why), but my VMs powered own and moved to different nodes,
the only issue is, it seemed to have changed the vlan ID on the NICs?
Which VLANs changed during the reboot of the host?
Just the VLANs on the hosts NICs, in a way the VMs are still connected to
the correct VLANs?
Has anybody seen this before?
It is possible to run a network configuration, which does not persist and
is reverted during reboot this way.
Please find more details in
http://ovirt.github.io/ovirt-engine-api-model/master/#services/host/metho...
or the
"Save network configuration" checkbox in the "Setup Host Networks"
dialog.
In recent oVirt versions this checkbox cannot be unselected anymore to
avoid unexpected situations.
I am just trying to establish if this was changed on the node
networking
side, or inside of the VM.
If a virtual NIC is connected to a logical network with a VLAN tag, there
is no intended way for the VM to modify this tag.
Thank you
