x86: Incorrect MSR_DEBUGCTL handling lets guests enable BTS

ISSUE DESCRIPTION The DEBUGCTL MSR contains several debugging features, some of which virtualise cleanly, but some do not. In particular, Branch Trace Store is not virtualised by the processor, and software has to be careful to configure it suitably not to lock up the core. As a result, it must...

Overcommitting pCPUs on individual XenServer VMs

Citrix recommends that you do not run a VM with more virtual CPUs vCPUs than the number physical CPUs pCPUs available on the XenServer host. The number of pCPUs available to XenServer can change even after the installation of VMs. For example, through actual hardware changes, changes in the BIOS...
