libvirt version - 8.0.0-1ubuntu7.10 I see in libvirt log the following messages that may be relevant (at least they started approximately at time of problem start) ``` Failed to connect socket to '/var/run/libvirt/virtlxcd-sock': No such file or directory End of file while reading data: Input/output error ``` Also I see repeating CloudStack agent errors when the problem starts (at least in some of hosts) ``` 2025-01-14 13:51:37,619 WARN [kvm.resource.LibvirtConnection] (agentRequest-Handler-2:[]) (logid:60e624f6) Can not find a connection for Instance i-2-2157-VM.

Opening a new one ``` After libvirt restart, CloudStack agent managed to connect to libvirt, and logs started looking regular. Seems that's the issue. But we had no issue with our KVM hosts without CloudStack. Please advise.
