Increased number of virtual machines supported in a cluster [Hyper-V R2]

  • Artykuł

When we released Windows Server 2008 R2 we stated that we would support up to 384 virtual machines running on a single instance of Hyper-V – but only up to 64 virtual machines running on a node of a cluster.

Last week we announced that we now support up to 384 virtual machines running on a node of a cluster – as long as the total number of running virtual machines in the cluster does not exceed 1000.

You can read more about this on the “Requirements and Limits” page on TechNet: https://technet.microsoft.com/en-us/library/ee405267(WS.10).aspx

Cheers,

    Sorry to be out of topic... But I've got a big question about memory in Virtual PC (version 2004/2007). Virtual PC 2004 doesn't run on Windows 64-bit host and Virtual PC 2007 for Windows 64-bit host is still a 32-bit program. Despite that fact, Virtual PC 2004 and Virtual PC 2007 are designed to handle 3.6 GB per virtual machines (see manual), even on 32-bit hosts without PAE support. But to my acknowledge, a 32-bit application cannot manage more than 2GB (or sometimes up to 3GB thanks to LARGEADDRESSAWARE). Because Virtual PC 2004 and 2007 are single-thread applications, I don't understand how they are able to handle more than 3GB for all virtual machines at the same time. How is it possible ? Thank you
