17.6. Verifying virtualization extensions
Use this section to determine whether your system has the hardware virtualization extensions. Virtualization extensions (Intel VT or AMD-V) are required for full virtualization.
Can I use virtualization without the virtualization extensions?
If hardware virtualization extensions are not present you can use Xen para-virtualization with the fedora kernel-xen package.
Run the following command to verify the CPU virtualization extensions are available:
$ grep -E 'svm|vmx' /proc/cpuinfo
The following output contains a vmx entry indicating an Intel processor with the Intel VT extensions:
flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush
dts acpi mmx fxsr sse sse2 ss ht tm syscall lm constant_tsc pni monitor ds_cpl
vmx est tm2 cx16 xtpr lahf_lm
The following output contains an svm entry indicating an AMD processor with the AMD-V extensions:
flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush
mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni cx16
lahf_lm cmp_legacy svm cr8legacy ts fid vid ttp tm stc
The "flags:" content may appear multiple times for each hyperthread, core or CPU on in the system.
