Does my CPU support Xen?

For a para-virtualized guest, your CPU only needs to support the PAE flag:

$ grep pae /proc/cpuinfo

For a fully-virtualized guest, your CPU must support either the “vmx” flag for an Intel processor, or the “svm” flag if your processor is from AMD. Run this command to find out:

grep ‘^flags.*(vmx|svm)’ /proc/cpuinfo
