Hello,

In performing some maintenance on a node, I tried to migrate a VM to another node in the cluster. I got a warning on the migrate dialog "Cannot migrate conntrack state, target node is lacking support. Active network connections might get dropped."

I saw another thread with maybe the same warning. Cheiss says it's a bug in the qemu-server code, fixed qemu-server 9.0.18.

My nodes are all running pve 9.0.10, which includes qemu-server 9.0.21.

Should I open a new bug on Bugzilla?

Could you please ensure that all the nodes have the same version of qemu-server (>9.0.18) and refresh the ui (ctrl+shift+r)?
 
Good morning,

Confirmed that all nodes in the cluster have qemu > 9.0.18.

Refreshed the UI with Ctrl-Shift-R and performed a migration with the same VM. The issue did not reoccur.

Thank you!
