<div dir="ltr"><div><div><div><div>Hi RIch<br><br></div>Thanks for the reply.The libguestfs is working fine here and there are no issues regarding that on the ubuntu compute node.From the nova-compute logs on the compute node,it appears that the tap interface is not coming up on the compute node.<br>
<br></div>Also in the file driver.py at the path /opt/stack/nova/nova/virt/libvirt in the below section,<br><br><b>uuid = dom.UUIDString()<br> if event == libvirt.VIR_DOMAIN_EVENT_STOPPED:<br> transition = virtevent.EVENT_LIFECYCLE_STOPPED<br>

elif event == libvirt.VIR_DOMAIN_EVENT_RESUMED:<br> transition = virtevent.EVENT_LIFECYCLE_RESUMED<br><br></b></div>the compute node should go in the second part i.e in <b>libvirt.VIR_DOMAIN_EVENT_STARTED ,which it it missing.<br>
