Actually our checking for unsupported parameters is too strict about
cpumask, vcpupin and NUMA parameters and in general wrong.
First of all, we do support cpumask and consequently we don't have to prevent
domain definition in case cpumask is specified. Also we should allow vcpupin
parameters if they don't contradict with common cpumask. NUMA checking was also
wrong because def->numa is always allocated. Here we check that its content is
not specified.
Maxim Nestratov (4):
parallels: cpumask support
parallels: don't forget to unlock domain in
parallelsDomainHasManagedSaveImage
parallels: prevent domain define only if NUMA is really specified
parallels: prevent domain define only if vcpupin is specified

No need to check dom here. It is guaranteed to be set at this point.
As it might set off our coverity checker I'll touch up the patch.

While this is still correct as the rest of the vcpupin array is filled
by the default cpu pinning mask, the rest of the cpus can be skipped.
ACK regardless.
