Greetings all, I have a problem of attaching volume to vm,
After attaching a volume to a vm, there are no error display on horizon(but no success either), and I found the following error in the /var/log/nova/compute.log, ============================================ 2013-02-21 09:06:52 1588 TRACE nova.compute.manager [instance: 95763834-a8c4-4d53-bc46-2937379855a4] libvirtError: internal error unable to execute QEMU command '__com.redhat_drive_add': Device 'drive-virtio-disk1' could not be initialized .... 2013-02-21 09:06:52 1588 TRACE nova.openstack.common.rpc.amqp rv = meth(*args,**kwargs) 2013-02-21 09:06:52 1588 TRACE nova.openstack.common.rpc.amqp File "/usr/lib64/python2.6/site-packages/libvirt.py", line 419, in attachDeviceFlags 2013-02-21 09:06:52 1588 TRACE nova.openstack.common.rpc.amqp if ret == -1: raise libvirtError ('virDomainAttachDeviceFlags() failed', dom=self) 2013-02-21 09:06:52 1588 TRACE nova.openstack.common.rpc.amqp libvirtError: internal error unable to execute QEMU command '__com.redhat_drive_add': Device 'drive-virtio-disk1' could not be initialized ============================================== It looks like something problem happened by libvirtd? Did anyone have a similar problem like this before? Please give me a hint, Thanks, Jeff
