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.

Doesn't matter, this was sitting on my back burner while other stuff cooked too, and meanwhile the bug resolved itself. Good job bug ;-)

Yeah, it landed in 12.[23] and SLE11 via stable. This issue is clearly history, so we can close this one again. -- 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.
