CS 4.20.1 Urgent: Console not working after Upgrade from 4.20.0 to 4.20.1

[tatay188]

problem

After finishing the process and restarting the System VMs,

everything seems to be working fine, except the connectivity to the Console on proxy or any VM that was working before.

Additionally the latency increased after the migration - tested with pings only adding 200 ms - which is double than before - to the systemVMs compared to 4.20.0

versions

Cloudstack 4.20.1
Ceph storage primary
EMC Unity secondary
Guest VXLAN
Public VLAN

Pings are successful to internet and to management. However latency is higher.

The steps to reproduce the bug

1. Upgrade to 4.20.1
2. enable VMs
3. try to connect to console to proxy or to any VM, none works.
4. Restarted the SystemVMs again - still does not work.
   ...

What to do about it?

No response

can you destroy the system vms , and retry after new system vms are created ?

Thank you Wei, That worked on the second Attempt after I restarted the KVM agent again - first attempt did not work without the KVM restart - I did check all the logs, there are no warnings or errors.

The console died after the Hypervisor restarted, I restarted the SystemVMs, and did not work.
I restarted everything, and did not work.
At this time I have no console access.
