Hey Anthony, I see this behaviour on Windows 2008 R2 VM's. I have turned off C state already but still seeing the same issue.
I honestly don’t recall seeing turbo mode in the bios but I'll take another look.

Can you provide more information about the VM? Or it may be caused by advanced cpu C state or turbo mode, you may need to turn off C state or limit it to C2 and turn off turbo mode in BIOS.

At first glance it looks like it's a Xenserver issue but I thought I would see if anyone has come across this before. Software = Xenserver 5.6 SP2 Host = HP DL360 G6 2x E5505 2.0Ghz 72GB RAM all the bios tweaks done.
