As of recently without any change to libvirt config it started misbehaving. If i use cpu pinning (<cputune> in xml) i cant start VM any more. Error: > Unable to write to > '/sys/fs/cgroup/cpuset/machine.slice/machine-qemu\x2dwin.scope/vcpu0/cpuset.cpus': > Permission denied Permissions on relevant dir: > % ls -lah /sys/fs/cgroup/cpuset/machine.slice > total 0 > drwxr-xr-x 2 root root 0 Kov 2 18:32 . > drwxr-xr-x 5 root root 0 Kov 2 18:30 .. > -rw-r--r-- 1 root root 0 Kov 2 18:30 cgroup.clone_children > -rw-r--r-- 1 root root 0 Kov 2 18:30 cgroup.procs > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.cpu_exclusive > -rw-r--r-- 1 root root 0 Kov 2 16:29 cpuset.cpus > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.effective_cpus > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.effective_mems > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.mem_exclusive > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.mem_hardwall > -rw-r--r-- 1 root root 0 Kov 2 16:29 cpuset.memory_migrate > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.memory_pressure > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.memory_spread_page > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.memory_spread_slab > -rw-r--r-- 1 root root 0 Kov 2 16:29 cpuset.mems > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.sched_load_balance > -rw-r--r-- 1 root root 0 Kov 2 18:30 cpuset.sched_relax_domain_level > -rw-r--r-- 1 root root 0 Kov 2 18:30 notify_on_release > -rw-r--r-- 1 root root 0 Kov 2 18:30 tasks Any idea why this would be? libvirtd runs as root. Should work. I didnt update libvirt when this appeared.
P.S. hope its not too offtopic, if it is - sorry _______________________________________________ vfio-users mailing list vfio-users@redhat.com https://www.redhat.com/mailman/listinfo/vfio-users
