Libvirt pool cannot see or create rbd clones
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

Re: ceph rbd pool and libvirt manageability (virt-install)
Hello everybody,
virt-install --version
1.4.0
How do I create a ceph network disk with virt-install without having to
edit it?

Hello everybody,
I created a rbd pool and activated it, but I can't seem to create
volumes in it with virsh or virt-install?

couple of ceph/rbd questions
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:

RBD snapshots
Dear libvirt users, I'm stuck on this subject and would appreciate a
working example as this looks a supported feature :)
After many tries and packages backports, here is my current setup:

Here is the relevent domain xml parts:

Re: Problem using virt-sysprep with RBD images
Hello Rich,
Interesting. Thanks for the explanation.
When you specify an rbd on the command line for virt-sysprep, do you expect
the path to include the monitor address?
e.g.:
>> virt-sysprep -a rbd://host-name/pool-name/device-name
If I understand correctly, libvirt is able to understand the ceph
configuration, so when I create a device with qemu-img I only specify the
protocol and

Using libvirt to access Ceph RBDs with Xen
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

Problem Connecting to RBD images using Sys::Guestfs Perl Module
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:

Create RBD Format 2 disk images with qemu-image
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
