cpuset.mems - Device or resource busy

[lejeczek]

Hi guys

On Centos 9 I get these in journal:

...

libvirt version: 8.0.0, package: 1.el9 (builder at centos.org, 
2022-01-14-15:00:06, )
hostname: dzien.mine.private
Unable to write to 
'/sys/fs/cgroup/machine.slice/machine-qemu\x2d4\x2dubusrv2.scope/libvirt/cpuset.mems': 
Device or resource busy

...

each time I do:

-> virt-admin daemon-log-outputs

There is more VMs running on the host but it's only these Ubuntu VMs 
Libvirt is not happy about.

Any and all suggestions very appreciated.

many thanks, L
