Virtualization hardware requirements?

The Host Server is the physical computer that will host your virtual machines. The host server can be a machine you’ve rented from one of our partners or one of your own in-house machines. This guide shows how to use one of your own machines as a host server.


  • 64 bit x86 processor with Intel® VT or AMD-V™ technology.

  • CD/DVD-ROM reader or USB port.

  • Minimum 1 GB of RAM.

  • Hard drive (min 20 GB) or NFS storage.




Does your cpu supports virtualization?

This is how you check it

egrep '(vmx|svm)' --color=always /proc/cpuinfo

If you get vmx (intel) or svm – (amd) it does.

root@digitalwhores:/home# grep --color vmx /proc/cpuinfo
flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm rep_good nopl pni vmx cx16 popcnt hypervisor lahf_lm

XEN kernel? try

cat /sys/hypervisor/properties/capabilities


My PowerEdge doesn’t?! f*ck!



VT-x, shows in /proc/cpuinfo as the vmx flag. (grep vmx /proc/cpuinfo)

AKA Vanderpool

See Wikipedia’s article on x86 virtualization, for a list of processors that include it.
