Xen Server 5.6 Sp2 The VM is Windows Server 2008 R2 Standard 4 vCPUs have been allocated
The machine has been rebooted and has correct version of xen tools installed.
In the device manager I see 4 cpus but in the task manager I only see one. In the performance monitor for xen I only see one cpu being utilized.
I have read that this issue could be attributed to single vs multi processor mode in windows but that seems to only be the case for 2003?
