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 any way to have qemu-img create RBD Format 2 images or am I better off

Hello everybody, This is a cross post to libvirt-users, libguestfs and ceph-users. I came back from FOSDEM 2016 and this was my 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

Hey Hilko, >> I'm guessing that you're using Ubuntu, am I right? Pretty good guess. :) For the time being I'm using 13.10. I know I've said it previously, but your right, I should include that info so I don't make people have to go digging. How do you normally deal with that warning? I typically rename the kvm binary, then link qemu-system-x86_64 but my concern is

Hello, I'm trying to using virsh update-device to update the CDROM from type='file' to ceph rbd iso with type='network'. But I always get error: Failed to update device from disk error: internal error: unable to execute QEMU command 'change': error connecting: Operation not supported I'm using libvirt-libs-3.10.0-1.el7.x86_64 with centos7.4 my original cdrom xml:

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

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'

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 get the same effect? Thanks

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, I am doing some experimentation with xen and Ceph and have a problem booting my guest when my disk = [] uses an alternate block script. Installation from a .iso was ok since the boot device was a file but now trying to boot from the rbd neither the hvmbuilder or pygrub can start as they treat the first value after target= as the /dev node to try and use. My disk parameter looks like: disk =
