Re: [Xen-devel] [PATCH] CPU affinity reset during save/restore

[Jiri Denemark <jdenemar@xxxxxxxxxx>]

Hi,

This is an improved patch for restoring CPU affinity on domain resume.

I've added a try-except around self._setCPUAffinity() in resum() so that the
domain can be resumed on different HW, where CPUs mentioned in the 'cpus' list
are not available. In that case, the affinity is just ignored. Without this
improvement, such domain would fail to resume with invalid argument.
