Helping virtualize the datacenter…

Where’s my CPU Affinity??

leave a comment »

We were having a discussion today over a vendor that said they currently do not support virtualizing their server application because of the “real-time clock” issues with virtualization, but they were working on this.  This led me to go find the VMworld 2008 presentation on Real-Time Applications.  The solution in the presentation was to set CPU Affinity for the VM.  Well, for the next 15 minutes or so, we went looking for CPU affinity with no luck in finding it.  Finally, we stumbled across it….

CPU affinity is hidden in the preferences for the VM when the VM is actively part of a DRS cluster.  For VMs in the DRS cluster with DRS disabled, CPU affinity can be found under the Advanced CPU selection in the resources tab.
