    Intel Xeon W3520 and hvm support

      I have Dell T3500 workstations.  I'm running centos 5.5 (xen kernel) on a box.  I have one pvm machine running already.  I need to import another virtual machine that was created using hvm support.

       

      The T3500 has an Intel(R) Xeon(R) CPU W3520  @ 2.67GHz chip.  However, when I check this chip to see if it can support hardware virtualization, it appears it can't:

       

      [rootXen]#  cat /proc/cpuinfo |grep vmx
      [rootXen]#  cat /proc/cpuinfo |grep svm
      [rootXen]#

       

      Can this chip be updated to enable hvm?

       

      thanks

          It appears the WS3520 chip does support hardware virtualization.

          The following tables list Intel and AMD CPUs that support hardware virtualization:

          So....... I've been in the bios and I've turnd on virtualization but still hvm appears not to work.

            The following is the solution to this issue.  Although xen was installed on the initial system when the host system was being built, apparently some

            necessary items/packages were omitted.

             

            After doing the following on the host system:

             

              572   yum install libvir*
              573   yum groupinstall xen

             

             

            I rebooted the system and checked the cpu info again.

             

            [root@atoz ~]#  cat /proc/cpuinfo |grep svm
            [root@atoz ~]# cat /proc/cpuinfo |grep vmx
            flags           : fpu tsc msr pae cx8 apic mtrr cmov pat clflush acpi mmx fxsr sse sse2 ss ht nx constant_tsc ida nonstop_tsc pni vmx est ssse3 sse4_1 sse4_2 popcnt [8]

             

            It seems hardware virtualization (vmx) is now available.
