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

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'

Hi everybody, my background: I'm doing Xen since 10++ years, many years with DRBD for high availability, since some time I'm using preferable GlusterFS with FUSE as replicated storage, where I place the image-files for the vms. In my current project we started (successfully) with Xen/GlusterFS too, but because the provider, where we placed the servers, uses widely CEPH, we decided to

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.

Hi, A bit of explanation of what I''m trying to achieve : We have a bunch of homogeneous nodes that have CPU + RAM + Storage and we want to use that as some generic cluster. The idea is to have Xen on all of these and run Ceph OSD in a domU on each to "export" the local storage space to the entire cluster. And then use RBD to store / access VM images from any of the machines.

Hi, I''ve been working on getting a working blktap driver allowing to access ceph RBD block devices without relying on the RBD kernel driver and it finally got to a point where, it works and is testable. Some of the advantages are: - Easier to update to newer RBD version - Allows functionality only available in the userspace RBD library (write cache, layering, ...) - Less issue when

TLDR: Why is virsh migrate --persistent --live domain qemu+ssh://root@host/system --xml domain.ceph.xml not persistent and what could i do about it? Hi, after years of beeing pleased with local storage and migrating the complete storage from one host to another, it was time for ceph. After setting up a cluster and testing it, its time now for moving a lot of VMs on that type of storage, without

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

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 directory libguestfs: trace: close

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

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 to QEMU.
