Description of problem:

# virt-sysprep -d server-clone-test --firstboot firstboot.sh
>> Examining the guest ...
>> Fatal error: exception Guestfs.Error("rbd: image name must begin with a '/'")

The guest has rbd (Ceph) drives:

>>     <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>                                                                  

Note the name field does not begin with a / (even though this
is valid).  Replacing the <source/> element with:

>>       <source protocol='rbd' name='/libvirt-pool/server-clone-test'>         

fixes libguestfs but breaks the guest itself.

Version-Release number of selected component (if applicable):

libguestfs 1.22.4

Hello,

I can confirm this behavior in libguesstfs 1.24 from this build [1]

Comment 3 Richard W.M. Jones 2014-01-24 10:30:34 UTC 
These are upstream now in libguestfs >= 1.25.27.
