Open Stack

Arindam,

If you don’t want to see the error in the logs you can configure /etc/nova/nova.conf to

[libvirt]
inject_partition = -2

The guest can then inject files and metadata after it starts up, which is more preferable.

Hi,

It will be very helpful if you can share your procedure. My libguestfs version is libguestfs-1.16.34-2.el6.x86_64

I've been done. The guestfs's python file has a bug.
Bug I forget what is version of the guestfs. If you can't deal the problem, I can find out what I have done.

Thanking a lot for helping me.

The guestfs error is due to a misconfiguration of guestfs and will only result in not having files injected before booting. Usually this is harmless as cloud-init like software will fix it after booting.

Glad the VM booted :)

changing /etc/libvirt/qemu.conf helped [Image removed by sender. Image removed by sender. Emoji] . clear_emulator_capabilities=0 was already set.

VM boots up, but it still has the same error in log.

If that doesn’t work try setting clear_emulator_capabilities=0

Try setting user and group to root in /etc/libvirt/qemu.conf
