Hi guys On Centos 9 I get these in journal: ... libvirt version: 8.0.0, package: 1.el9 (builder@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
