I'm running a number of VMs that are RHEL 5.X 32 and 64 bit standard (i.e. non custom) kernels on ESX 3.5u4. I'm trying to figure out if/when I'd ever want to install the OSPs vs the rpm that comes thru ESX.
I do have some VMs which are running 5.X 32bit+PAE (which I understand is
not-supported under ESX due to high context switches) - the vmware tools will install into those, so even there I'm not sure when I'd use the OSPs. Of course, the plan is to migrate these to supported 64 bit OSs.
