Why does a virtualised "Windows XP" running under "Hyper-V Server 2008 R2" use only one of the four allotted virtual processors?
Posted on 2010-11-18
We used the disk2vhd tool to convert a running Windows XP Professional system with a quad-core processor, and attached the resulting image to a guest running under Hyper-V Server 2008 R2.
This VM has 4 virtual processors allotted to it. Everything seems to be normal ("new" hardware required drivers, etc.), but taskmgr shows only one of the allotted 4 uP being used; Device Manager lists all 4 uPs though. Has anybody else encountered this problem before? If so, how can this be resolved (the VM needs 4 uPs for our work).
Is this a potential licensing issue?
