vm disappear after migration
Hi all,
we have an installation of cloudstack 4.5 on Ubuntu 16.04 with KVM as
hypervisor.
We have one zone only and an advanced network configuration with some
isolated networks.
Since a few days we have a problem while migrating some VMs from any
hypervisor to any other one, but the problem does not affect all VMs.
Some VMs migrate from an host to another but disappear from the network.
I can enter via proxy-console but it seems they are disconnected from
the network, the router is not pingable in both directions (router to vm
and vice versa). Other VMs and routers of the isolated network continue
to work.
In some cases the VMs return visible if I migrate them back to the
original host, in some other cases I have to stop and restart them.
Note that this problem has only appeared recently, we did not make
changes to network topology, the same VMs that cause problems now didn't
before.
Cloudstack doesn't log any problem...
Any ideas?

Hi Boris,

Also, log onto your hypervisor hosts and run "virsh list" and see if you can find the actual VM. Are you running VRs in redundant mode?
