<div dir="ltr"><div><div><div>Hi Rich<br><br></div>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.<br>
<br></div>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.<br>

</div>The most common reason is that nested virt is broken. libguestfs is the canary<br>
in the mine here, not the cause of the problem.<br>
