Open Stack

Hi RIch

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.

Also in the file driver.py at the path /opt/stack/nova/nova/virt/libvirt in
the below section,











*uuid = dom.UUIDString()        if event ==
libvirt.VIR_DOMAIN_EVENT_STOPPED:            transition =
virtevent.EVENT_LIFECYCLE_STOPPED        elif event ==
libvirt.VIR_DOMAIN_EVENT_STARTED:            transition =
virtevent.EVENT_LIFECYCLE_STARTED        elif event ==
libvirt.VIR_DOMAIN_EVENT_SUSPENDED:            transition =
virtevent.EVENT_LIFECYCLE_PAUSED        elif event ==
libvirt.VIR_DOMAIN_EVENT_RESUMED:            transition =
virtevent.EVENT_LIFECYCLE_RESUMED*
the compute node should go in the second part i.e in

*libvirt.VIR_DOMAIN_EVENT_STARTED ,which it it missing.*
The output of brctl show is follows on the ubuntu compute node--

brctl show
bridge name    bridge id        STP enabled    interfaces
qbr06865952-4f        8000.6654b7d239b7    no        qvb06865952-4f
qbr9cbe0875-42        8000.da3180e79619    no        qvb9cbe0875-42
qbrb61ecf20-cf        8000.e24a1b9d71c0    no        qvbb61ecf20-cf
qbrda8485b3-73        8000.f602a0f09835    no        qvbda8485b3-73

The main problem is that the tap interface is not able to come up.Below are
the nova-compute logs..
