Thanks Jim, Looking at the logs for the working and non-working setups, the command line for QEMU is identical and the qmp commands almost the same: they both do "query-chardev" and "query-vnc" and the working setup does an additional "qmp_capabilities" which is likely not relevant. So I guess it must be in QEMU - I'll head over to the bug tracker. Thanks

It's QEMU 4.2.1-lp152.9.6.1. I've tried updating it from the Open Build Service repos but there's too many version conflicts.

Hi, I've recently been working on setting up a set of libvirt compute nodes that will be using a ceph rbd pool for storing vm disk image files. I've got a couple of issues I've run into. First, per the standard ceph documentation examples [1], the way to add a disk is to create a block in the VM definition XML that looks something like this: <disk type='network'

i will test it out and will update you.. Thankyou so much for your reply kind regards Shumaila Naeem Software Engineer , Ovex Technologies On Thu, Mar 13, 2014 at 5:15 PM, Richard W.M. Jones <rjones@redhat.com>wrote: > On Thu, Mar 13, 2014 at 03:06:17PM +0500, Shumaila Naeem wrote: > > >

Hi there, Since upgrading to openSUSE 15.2 (which includes libvirt 6.0.0) the virtual guests don't get their RBD disks made available to them. On openSUSE 15.1 (which includes libvirt 5.1.0) that worked fine. The XML is as follows: <domain type='xen' id='7'>   <name>mytwotel-a</name>   <uuid>a56daa5d-c095-49d5-ae1b-00b38353614e</uuid>  

I use "virsh pool-define rbd.xml" to create a rbd storage pool,but get this error virsh pool-define /tmp/rbd.xml error: Failed to define pool from /tmp/rbd.xml error: internal error: missing backend for pool type 8 rbd.xml <pool type="rbd"> <name>cloudstack</name> <source> <name>cloudstack</name> <host

Eric, Well, in case where several servers may start the same virtual machines after a reboot for exemple. http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-August/003887.html I've seen this hook here : http://www.wogri.at/en/linux/ceph-libvirt-locking/ But it's a hook... Yes, I may try to write a patch. My coding skills are surely not as good as yours but I 'd be glad to make

Hi, One short question : Is there any chance to see locks on rbd/images in the next release ? Thank you :)

You can use the new version without installing it. However you would need to be able to install a compiler and other dependencies, which may not be possible on a production

Hello everybody, virt-install --version 1.4.0 How do I create a ceph network disk with virt-install without having to edit it? <disk type='network' device='disk'> <driver name='qemu' type='raw'/> <auth username='libvirt'> <secret type='ceph' uuid='ec9be0c4-a60f-490e-af83-f0f27aaf48c9'/>

Hello everyone, To increase my odds of finding an answer I also wanted to ask here. This is my post from serverfault[1] in verbatim: While trying to get a cloned disk running from my OS snapshot I run into the problem that Libvirt cannot see existing images cloned from a snapshot. Created via: # rbd -p vmdisks clone vmdisks/coreos_2023@base vmdisks/coreos00.disk The base image has the one

Hi, I'm trying to build an active/active virtualization cluster using a Ceph RBD as backing for each libvirt-managed LXC. I know live migration for LXC isn't yet possible, but I'd like to build my infrastructure as if it were. That is, I would like to be sure proper locking is in place for live migrations to someday take place. In other words, I'm building things as if I were

Software in use: *Source hypervisor:* *Qemu:* stable-2.12 branch *Libvirt*: v3.2-maint branch *OS*: CentOS 6 *Destination hypervisor: **Qemu:* stable-2.12 branch *Libvirt*: v4.9-maint branch *OS*: CentOS 7 I'm experiencing an intermittent live migration hang of a virtual machine (KVM) with a ceph RBD volume attached. At the high level what I see is that when this does happen, the virtual

So, how likely is it possible to get this feature (two new events for the qemu hook)?

That's right, I need also that second hook event. For your information, for now I manage locks manually or via Ansible. To make hook manage locks, I still need to find out a secure way to run LVM commands from a non-root account, but this is another problem.
