I'm having some trouble creating KVM domains with RBD block devices using virsh. I've managed to get virsh to define the domain, but it gives an error when trying to start the domain: error: Failed to start domain test0 error: internal error process exited while connecting to monitor: char device redirected to /dev/pts/3 kvm: -drive file=rbd:rbd/t...

Hello, I would like to use RBD Format 2 images so I can take advantage of layering. However, when I use "qemu-img create -f rbd rbd:data/foo 10G", I get format 1 RBD images. (Actually, when I use the "-f rbd" flag, qemu-img core dumps, but it looks like that feature may have been deprecated [1]) Is there an...

Hello, I'm having trouble connecting to rbd images. It seems like somewhere the name is getting chewed up. I wonder if this is related to my previous troubles [1] [2] with rbd images. I'm trying to add an rbd image, but when I launch the guestfs object I get an error: >> libguestfs: trace: launch = -1 (error) I'm adding a s...

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' device='dis...

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>   <description>my...

Hello, I'm having a problem when trying to use virt-sysprep against vms that have rbd disk images.

...7th year or so and seen the awesome development around visualization going on and want to thank everybody for there contributions. I seen presentations from oVirt, OpenStack and quite a few great Redhat people, just like the last previous years. I personally been supporting Linux-HA (pacemaker) DRBD/iSCSI/KVM platform for years now and last year I started supporting Ceph RBD clusters with KVM hosts. But I keep hitting some ?pains? and I been wondering why they have not been solved and how I can best request help around this? Tools that don't seem to fully work with Ceph RBD yet: - virsh...

how to use python-guestfs to access rbd device? The function i found is g.add_drive_opts, but i dono know how it receive ceph's configuration. I found this link http://rwmj.wordpress.com/2013/03/12/accessing-ceph-rbd-sheepdog-etc-using-libguestfs/ Is that the only way i should use to access ceph rbd? Can we use python-guestfs to g...

I am running some qemu-kvm virtual machines via libvirt using Ceph RBD as the back-end storage. Today I was testing an update to libvirt-1.0.6 on one of my hosts and discovered that it includes this change: [libvirt] [PATCH] Forbid use of ':' in RBD pool names ...People are known to be abusing the lack of escaping in current libvirt to pass arbitrary args t...

Miscellaneous fixes to: - Handling of Ceph drives now works end-to-end (RHBZ#1026688). - In particular, you can now use rbd:/// URIs in guestfish (and they work). - Parse Ceph & NBD network drives from libvirt XML correctly, so that existing domains with Ceph/NBD drives can be added (eg. using guestfish -d option). - Add more testing of the above.

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 snapshot 'base' and is protected. The cloned disk is created just fine: # rbd -p vmdisks info coreos00.disk rbd image 'coreos00.disk': size 8.49GiB in 2174 objects order 22 (...

Hi, I'm trying to run virt-sysprep against a disk in Ceph RBD storage but I appear to be unable to do so. The commands (bold) and outputs I've had are: On Ceph node: *virt-sysprep -a rbd://localhost/libvirt-pool/ubuntu-12-04-beanstalk001* libguestfs: new guestfs handle 0x113b060 rbd://localhost/libvirt-pool/ubuntu-12-04-beanstalk001: No such file or d...
