After a suspend to RAM the libvirtd is pinned to a single cpu which results in all kvm instances using all the same core.

I found this bug in the RH bugzilla which describes the same problem: https://bugzilla.redhat.com/show_bug.cgi?id=714271

It also mentions that this is a kernel bug. Pointing to http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=8f2f... which should fix the issue.

Yes, 8f2f748b is tagged for stable, so this bug should be self-resolving. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Since systemd is responsible for mounting the cpuset cgroups, the RH libvirt folks opened a bug on systemd to include it there, without success afaict https://bugzilla.redhat.com/show_bug.cgi?id=813228 Main reason not to include it is that a proper kernel fix is making progress, and working around it in userspace is "futile". -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Mainline d35be8ba should fix it up properly, right?

Opps, sorry I missed the NEEDINFO... Yes, afaict, that commit should fix the issue, but I haven't tried e.g. on 12.3. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
