Thanks a lot for your suggestions , I guess it might be 2nd level
configuration issue ... will take more time on it , thanks


my 1st level host has following output when 'virsh capabilities'

<host>
    <uuid>c476d525-bba7-e211-98a9-9cd4d92d1300</uuid>
    <cpu>
      <arch>x86_64</arch>
      <model>SandyBridge</model>
      <vendor>Intel</vendor>
      <topology sockets='1' cores='4' threads='1'/>
      <feature name='erms'/>
      <feature name='smep'/>
      <feature name='fsgsbase'/>
      <feature name='rdrand'/>
      <feature name='f16c'/>
      <feature name='osxsave'/>
      <feature name='pcid'/>
      <feature name='pdcm'/>
      <feature name='xtpr'/>
      <feature name='tm2'/>
      <feature name='est'/>
      <feature name='smx'/>
      <feature name='vmx'/>
      <feature name='ds_cpl'/>
      <feature name='monitor'/>

      <feature name='ss'/>
      <feature name='acpi'/>
      <feature name='ds'/>
      <feature name='vme'/>
    </cpu>

while the output on 2nd level is

<host>
    <uuid>a1bb0066-80d2-f9db-aa4e-0520a0562875</uuid>
    <cpu>
      <arch>x86_64</arch>
      <topology sockets='1' cores='1' threads='1'/>
    </cpu>

cat /proc/cpuinfo
Make sure the cpu model and version is listed
on /usr/share/libvirt/cpu_map.xml

Hope this helps.

  Hi Kevin,
  Running devstack in a VM is perfectly doable.  Many developers use
  devstack inside a VM (I run mine inside a VM launched using libvirt
  on KVM).  I can't comment on the issue that you're encountering,
  but perhaps something wasn't configured correctly when you launched the
  VM?

  Solly Ross
