Hi Rich

I'm able to solve the problem regarding PAPR in libguestfs on my powerpc
ubuntu.By default the libguestfs was configuring pseries machine and
afterwards I changed it to my original machine i.e ppce500 .The changes are
performed in ./src/guestfs-internal.h file.

However still my VM is stucking in spawning state.The compute node is not
able generate the xml file required for running the instances which I have
checked by comparing the nova-compute logs of controller node aw well as
compute node since I'm able to run VM on controller node.

Thanks for the help,I'll let you know if any further issues.
