Hello,
in my case, the workaround to limit "dom0-cpus=1" makes my dom0s stable. But i
can't migrate (--live) any domUs any more. Also shutdown/halt of a domU hangs
after shutdown/halt. This doesn't happen with dom0-cpus=0.
Can anyone tell where to find 2.6.26-20? Till now i didn't find this on

SA_NODELAY at some point in the past AFAIR) that controls i

Severity: normal
