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:

Invalid argument
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.
Thanks,
Jon A
