Thanks Neo. Also wanted to tell that I downloaded libvirt xml for the guest to see number of queues and number of vcpus , I read in some posts that number of vcpus should be made equal to the number of queues , but I did nt find any mention of queue in the xml file for that guest.Below I have pasted the lines from xml file associating to vcpus :

Code:
<currentMemory unit='KiB'>6291456</currentMemory>
  <vcpu placement='static' current='4'>32</vcpu>

 </features>
  <cpu mode='custom' match='exact' check='partial'>
    <model fallback='allow'>Skylake-Server-IBRS</model>
    <topology sockets='16' cores='2' threads='1'/>
    <numa>
      <cell id='0' cpus='0-3' memory='6291456' unit='KiB'/>
    </numa>
  </cpu>
  <clock offset='variable' adjustment='0' basis='utc'>
    <timer name='rtc' tickpolicy='catchup'/>
    <timer name='pit' tickpolicy='delay'/>
    <timer name='hpet' present='no'/>

 <numa>
      <cell id='0' cpus='0-3' memory='6291456' unit='KiB'/>
    </numa>
  </cpu>
  <clock offset='variable' adjustment='0' basis='utc'>
    <timer name='rtc' tickpolicy='catchup'/>
    <timer name='pit' tickpolicy='delay'/>
    <timer name='hpet' present='no'/>
  </clock>

</cpu>
  <clock offset='variable' adjustment='0' basis='utc'>
    <timer name='rtc' tickpolicy='catchup'/>
    <timer name='pit' tickpolicy='delay'/>
    <timer name='hpet' present='no'/>
  </clock>
