You need a fairly recent processor: I think anything multicore from AMD
has support, whereas Intel chips may or may not have it depending on how
Intel feels.
http://fedoraproject.org/wiki/Docs/Fedora8VirtQuickStart#Fully-virtualized_guests_.28HVM.2FIntel-VT.2FAMD-V.29 says:
To run fully virtualized guests in Xen or KVM, host CPU support is
needed. This is typically referred to as Intel VT, or AMD-V. To
check for Intel VT support look for the ‘vmx’ flag, or for AMD-V
support check for ‘svm’ flag:
....For Intel....
grep vmx /proc/cpuinfo
flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall nx lm constant_tsc pni monitor ds_cpl vmx est tm2 cx16 xtpr lahf_lm
....For AMD....
grep svm /proc/cpuinfo
flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm cr8_legacy
If both those commands return nothing, you don't have hardware
virtualisation support.
Hope this helps,
James.
