Re: Errors attaching RBD image to a running VM

O.k, I got you -;

> NO, debian 3.14.44-1-amd64, QEMU emulator version 2.3.0, openstack kilo, libvirt 1.2.9, ceph version 0.80.7

How about this?

> And please attach logs related to Ceph, qemu and livbirt.

NO, debian 3.14.44-1-amd64, QEMU emulator version 2.3.0, openstack kilo, libvirt 1.2.9, ceph version 0.80.7

I am to attach volume to nova instance if instance is in shutoff state. For that following steps I did.

I restarted libvirtd and libvirt-guests, after libvirt-guests restart vm went to shutoff state but nova is not updated instance state still it is in running state, now I did volume attach it went fine.
If I restart nova-compute instance state is updated with shutoff state, if I try to start instance the below error I am facing.
 
libvirtError: internal error: process exited while connecting to monitor: 2015-08-27T11:16:02.726265Z qemu-system-x86_64: -drive file=rbd:volumes/volume-ee7f6e3d-8269-4ffc-8d62-a881a0d7116f:id=cinder:key=AQCfEdxVUP13MBAAv4Oj7twFIxaF1BXyY1PkRQ==:auth_supported=cephx\;none:mon_host=192.168.245.2\:6789\;192.168.245.3\:6789\;192.168.245.4\:6789,if=none,id=drive-virtio-disk1,format=raw,serial=ee7f6e3d-8269-4ffc-8d62-a881a0d7116f,cache=none: Unknown protocol 'rbd'

Still this error "Errors attaching RBD image to a running VM" is there.

Thanks & Regards,

Hello,

My question from first look at is that, is it your environment?

> Currently running SL 6.3, OpenStack Folsom packages from EPEL, Libvirt 
> 0.9.10, QEMU 1.2.1 built from an epel-testing SRPM for RBD support, 
> and Ceph 0.54

If it's true, you have to upgrade SL and Ceph as much as you can.
Because, as you might notice, there have been a bunch of bug fixes.

And please attach logs related to Ceph, qemu and livbirt.
