vSphere 4.0 introduced virtual hardware version 7, which added hot plug support for virtual devices and hot add support for memory and virtual CPUs.  Finding the operating systems that could be used with hot add was a somewhat difficult process, and there wasn't a readily available "official" resource that could be used for reference.  With the release of v 2.0 of the VMware Compatibility Guide, finding this information just got a lot easier.  So, what operating systems can be used with hot add memory and vCPU?






There are many!  Rather than posting large tables that would require constant updating, I posted the direct link to the VMware Compatibility Guide.  This way the results shown will always be current.


Thanks for reading.
