How, in general, does one determine if a PC supports hardware virtualization? I use VirtualPC to set up parallel test environments and I\'d enjoy a bit of a speed boost.
Try cpu-z or SecurAble on windows or on linux, cat /proc/cpuinfo
and look for the flags: vmx (Intel) or svm (AMD)
All of those will tell you if the hardware supports it, but as others said it must be enabled in the BIOS. (But checking first will avoid an unnecessary reboot...)
