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 slash: if (exportname[0] != '/') { error (g, _("rbd: image name must begin with a '/'")); return NULL; } I tried to comment this out and recompile guestfs, but I get an error: make[2]: Entering directory `/root/libguestfs-1.25.6/builder' ocamlfind ocamlopt -g -warn-error CDEFLMPSUVYZX -package str,unix -I ../src/.libs -I ../ocaml -I ../mllib -package gettext-stub -c builder.ml -o builder.cmx File "builder.ml", line 53, characters 4-14: Error: Unbound value List.iteri make[2]: *** [builder.cmx] Error 2 make[2]: Leaving directory `/root/libguestfs-1.25.6/builder' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/libguestfs-1.25.6' make: *** [all] Error 2 Can you provide some assistance resolving this compile error please? Is there perhaps a better place to pull the source from? Thanks, Jon A [1] http://libguestfs.org/download/1.25-development/libguestfs-1.25.6.tar.gz On Tue, Nov 5, 2013 at 2:01 AM, Richard W.M.

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:
root@kitt:~/libguestfs-1.22.4# virt-sysprep -d server-clone-test --firstboot firstboot.sh Examining the guest ... Fatal error: exception Guestfs.Error("rbd: image name must begin with a '/'")
My Disk definition is as follows:
<disk type='network' device='disk'> <driver name='qemu'/> <source protocol='rbd' name='libvirt-pool/server-clone-test'> <host name='192.168.0.40' port='6789'/> <host name='192.168.0.35' port='6789'/> <host name='192.168.0.2' port='6789'/> </source> <target dev='hdb' bus='ide'/> <address type='drive' controller='0' bus='0' target='0'
unit='1'/>
</disk>
I can resolve this error by changing the name of the libvirt-pool:
<source protocol='rbd' name='/libvirt-pool/server-clone-test'>
But this causes an error when attempting to boot the vm:
root@kitt:~/libguestfs-1.22.4# virsh start server-clone-test error: Failed to start domain server-clone-test error: internal error: process exited while connecting to monitor: W: kvm binary is deprecated, please use qemu-system-x86_64 instead char device redirected to /dev/pts/5 (label charserial0) qemu-system-x86_64: -drive

I'm currently using libguestfs-1.22.4 and I did run into a known bug [1] that I was able to patch, but I don't think that's related to the issues with disk naming.
Is there a way to give virt-sysprep a rbd with the -a flag, or is there a better way to sysprep vms? I would like to avoid having to edit the vm config if possible.
This is a bug basically. I have filed a bug report here:
https://bugzilla.redhat.com/show_bug.cgi?id=1026688
It would be helpful to try with a newer version of libguestfs. Ubuntu has just pushed the 1.24.0 package. I don't know if it'll help or not, but it would be useful to know if the behaviour changes.
