You have a dualprocessor virtual machine (vm)that has affinity set so that the virtual cpus are pinned to cpu 3 and 4 in virtualcenter. The vmalso has a reservation setting guaranteeing it 100% of available resources for those two cpus. Performance is poor in this vm, however performance for all other vms on this host is acceptable. What can you do to improve performance for this vm?
Change the cpu affinity setting to ensure that the virtual cpus are running on two separate physical cpus on the host.
Set cpuaffinity on all other vms prohibiting them from using cpu 3 and 4.
Change the cpu share allocation form "normal" to "high"
Remove the reservations on the cpus in order to allow the vmkernel to switch the virtual cpus between cpu 3 and 4 as needed.
