After a 'virsh blockpull', 'virsh snapshot-list --tree' o/p does not reflect reality
Hi (Eric?),
A couple of questions while using the 'virsh blockpull'
Summary:
1] Created snapshots this way: base<-snap1<-snap2<-snap3 (online, external snapshot
--disk-only)
2] I did a 'virsh blockpull' from snap2 into snap3
3] Next, did another 'virsh blockpull' from snap1 into snap3
- Here, 'qemu-img info /path/to/snap3' shows its backing file

Re: Problem Connecting to RBD images using Sys::Guestfs Perl Module
Hello Richard,
I'm using:

I honestly don't remember if the currently installed version is from the
tarball or pulled from the github source... Now that you mention it, I
think it could even be the version with my "hack" to fix virt-sysprep...
Which version are you building? I see there's a:

Re: ceph rbd pool and libvirt manageability (virt-install)
Hello everybody,

How do I create a ceph network disk with virt-install without having to
edit it?

Problem using virt-sysprep with RBD images
Hello,
I'm having a problem when trying to use virt-sysprep against vms that have
rbd disk images. When I run virt-sysprep I get the following error:

Re: Problem using virt-sysprep with RBD images
Hello Richard,
Thanks for the reply.
Indeed this behaviour exists in 1.25.6.
Grepping through the source [1], there are a number of files in
"./po/*.po[t]?" that contain this message, but I think it's ./src/drives.c
where the fail condition is actually detected / set.
On line 300 there is an if statement that checks the first character is a

Re: Problem using virt-sysprep with RBD images
Hello Richard,
Haha, ok, here's a good one: I commented that if statement out at line 300,
applied your patch (I see you updated the github of this code, perhaps
that's the best place to grab the code from), and when I run virt-sysprep,
I get the following parameter for my disk drive:

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:

Repetitive RBD disk definitions
Hi,
I'm using libvirt 5.0.0 on a Ceph cluster. The VM disks are all from
the same Ceph pool, so all my <disk> elements are basically the same:

<driver name="qemu" type="raw" cache="none"/>
<source protocol="rbd" name="vmdisks/VOLNAME">

While I realize you want to trivially clone VMs with some state at
random point in time, you might want to look into `virt-builder` about
cloning VMs. It has some sensible advice:
