Basically I have 2 virtuals on 2 different Hyper-V servers where I have allocated 4 processors however within the virtual the OS thinks it only has one processor. When I run HyperV_Mon it confirms that the virtual is only utilizing the 1st processor.
The Hyper-V server is running Server 2008 R2. Both servers are hosting about 10 virtual servers. The operating systems of the virtuals vary from Server 2003, 2008 and 2008R2. I am only having issues with virtuals running Server 2003 however not all my 2003 virtual servers have the issue.
The 2 virtuals with this issue are 32bit OSs and don’t seem to have any noticeable configuration differences from the 2003 virtuals that see all the allocated processors.
Both the virtuals with this issue (as with the working ones also) were created using the Sysinternals Disk2vhd tool v 126.96.36.199.
Any ideas as to why my virtual servers don’t see all 4 allocated processors?
