Hi RIch Thanks for the reply.The libguestfs is working fine here and there are no issues regarding that on the ubuntu compute node.From the nova-compute logs on the compute node,it appears that the tap interface is not coming up on the compute node.

Hi Rich
Can you help me regarding the possible cause for VM stucking at spawning
state on ubuntu powerpc compute node in openstack using devstack.

Re: [openstack-dev] nova-compute vfsguestfs
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.

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

Re: [openstack-dev] nova-compute vfsguestfs
Hi Daniel
Thanks for the help.
The end result of my setup is that the VM is stucking at Spawning state on
my compute node whereas it is working fine on the controller node.
Therefore I'm comparing nova-compute logs of both compute node as well as
controller node and trying to proceed step by step.
I'm having all the above packages enabled
Do you have any idea regarding reason for VM stucking at spawning state.

VFSGuestFS requires the libguestfs python module & corresponding native
package to be present, and only works with KVM/QEMU enabled hosts.
VFSLocalFS requires loopback module, nbd module, qemu-nbd, kpartx and
a few other misc host tools
Neither of these should cause a VM getting stuck in the spawning
state, even if stuff they need is missing.

Daniel

[openstack-dev] nova-compute vfsguestfs
Hi
Below is the code to which I'm going to reffer to..
vim /opt/stack/nova/nova/virt/disk/vfs/api.py
#
try:
LOG.debug(_("Trying to import guestfs"))
importutils.import_module("guestfs")
hasGuestfs = True
except Exception:
pass
if hasGuestfs:
LOG.debug(_("Using primary VFSGuestFS"))
return importutils.import_object(
"nova.virt.disk.vfs.guestfs.VFSGuestFS",
imgfile, imgfmt, partition)
else:
LOG.debug(_("Falling back to VFSLocalFS"))
return importutils.import_object(
"nova.virt.disk.vfs.localfs.VFSLocalFS",
imgfile, imgfmt, partition)
###
When I'm launching VM from the controller node onto compute node,the
nova compute logs on the compute node displays...Falling back to
VFSLocalFS and the result is that the VM is stuck in spawning state.
However When I'm trying to launch a VM onto controller node form the
controller node itself,the nova compute logs on the controller node
dislpays ...Using primary VFSGuestFS and I'm able to launch VM on
controller node.
Is there any module in the kernel or any package that i need to
enable.Please help regarding this.
Thanks
Abhishek Jain
