[Libguestfs] [libguestfs] 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: --firstboot firstboot.sh '/'") My Disk definition is as follows: I can resolve this error by changing the name of the libvirt-pool: But this causes an error when attempting to boot the vm: kvm binary is deprecated, please use qemu-system-x86_64 instead file=rbd:/libvirt-pool/server-clone-test:auth_supported=none:mon_host=192.168.0.40\:6789\;192.168.0.35\:6789\;192.168.0.2\:6789,if=none,id=drive-ide0-0-1: pool name too short file=rbd:/libvirt-pool/server-clone-test:auth_supported=none:mon_host=192.168.0.40\:6789\;192.168.0.35\:6789\;192.168.0.2\:6789,if=none,id=drive-ide0-0-1: could not open disk image rbd:/libvirt-pool/server-clone-test:auth_supported=none:mon_host=192.168.0.40\:6789\;192.168.0.35\:6789\;192.168.0.2\:6789: 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.
