Thanks for catching it Lucia. The pending resources should have been taken more carefully.
When there is no host found where the VM can run, the following message is displayed: The host ABC did not satisfy internal filter CpuPinning because... It makes sense to continue with "it" after that. Also, in case of manual and resize and pin pinning, we should mention also the possibility that some cores have been exclusively pinned.
…pinnings In CpuPinningPolicyUnit, we need to apply the pending vds cpu resources also for manual and resize and pin policies. Otherwise we may end up with both, manual (or resize and pin) and dedicated vCPU pinned to a single pCPU.
In VdsCpuUnitPinningHelper::previewPinOfPendingExclusiveCpus, the CPU topology has been updated with an incorrect CPU pinning policy (the current VM's instead of the pending one). This may have caused that after the migration of a VM group with mixed exclusive and manual pinnings, some CPUs might end up to be pinned to both, manual and exclusive CPUs at once.

During the migration of a VM group with mixed exclusive and manual pinnings, some pCPUs might have ended up to be pinned to both, manual and exclusive vCPUs at once. This was caused by the fact that the pending vds cpu unit resources have not been applied for non exclusively pinned CPUs and that the application of the pending resources has not been correct (the current VM's cpu pinning policy was used instead of the pending one).
