Does my dual core AMD Athlon 64 X2 4400+ support AMD-V?

  • 772

I am trying to setup some VM's on Citrix XenServer but can't enable Hardware Virtualization support. In the XenServer install it prompted me to enable this, and upon creating a VM I got a "HVM required" error.

I have a dual core AMD Athlon 64 X2 4400+ processor - does this have support for AMD-V?

How can I enable this to run this software/VM's?

If it helps I am running:

  • a Mach Speed MSNV-939 motherboard with 3 gigs of RAM.
  • Pheonix Technologies 6.0 BIOS

Edit: It looks like the chip can do it, but not with the 939 socket, I need the AM2 socket. Can anyone confirm this?

Thank you,

    AMD added hardware virtualization with the AM2 socket. Your current chip is made for socket 939 and does not support hardware virtualization.

  2. Yes, it have. You should look at svm flag in your /proc/cpuinfo.

    Here is the output from my system that uses this processor (two lines are for two cores):

    $ grep svm /proc/cpuinfo 
flags       : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow rep_good nopl pni cx16 lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch

  3. You can use SecurAble to determine if your processor has Hardware Virtualization support.

    If you can't use SecurAble then try looking in the BIOS as it can be disabled by default.

    This article says that your Athlon 64 X2 4400+ has HV.

  4. According to wiki "AMD-V capability is also available on Athlon 64 and Athlon 64 X2 family of processors with "F" or "G" stepping on socket AM2" so not all AM2 CPUs support AMD-V.

    You can make sure with of CPU stepping via AMDCompare.com website.
