Bug#689861: Issues with Xen when all CPUs are available to dom0
Package: linux-image-2.6.32-5-xen-amd64
Version: 2.6.32-45
I am experiencing issues with Xen once all CPUs are available to dom0.
There is high "steal time" shown once I do not set one CPU available for
dom0 (doesn't matter what way is used - xend-config, Linux or Xen
hypervisor boot argument).
If all CPUs are available to dom0 all tries to start domU fail with
timeouts. More detailed description is in xen-utils bugreport opened by
me in July 2012 [1] with no response till today. It is reproducible on
two different servers running Xen (one Intel Xeon and second AMD Opteron).
Please consider if it is related to kernel or not.
Anyway - we just jump into situation where no dynamic domU's
configuration change is possible and this is causing us serious
manageability and serviceability issues.
