Launching vpn image issue

Hello,
I built cloudpipe image using base oneiric ubuntu iso and uploaded it to glance as a raw image.
(glance add is_public=true disk_format=raw container_format=ovf name="cloudpipe image" < cloudpipeimage.img)
I am trying to launch it using nova api(cloudpipe-create). It does not launch correctly. Though euca-describe-instances status says "running", I cannot vnc into that vm.
I see the following errors in nova-compute.log
guestmount command not found error and other erros following it. (Detailed log below)

I am running essex released version on oneiric. I could not find any package that has guestmount.
Is there any package that I am missing?
Thanks,
-Vijay

Re: Launching vpn image issue [In reply to]

hi

I found guestmount in libguestfs-tools-c package.
and I had such issue with guestmount in centos.

in ubuntu I thought by default nova-compute would use nbd . if you did not
change img_handlers flag.

By default loop,nbd,libguestfs injection methods are tried in that order.
You may need to ensure the nbd module is loaded for that method to work.

If you do need the extra capabilities of libguestfs, then...

According to http://packages.ubuntu.com/, there
is a guestmount package available for precise.
However there may be issues with that:
https://www.redhat.com/archives/libguestfs/2012-April/thread.html#00028

There are also oneric versions available independently:
http://libguestfs.org/download/binaries/ubuntu1004-packages/

For the record, the Fedora and the EPEL (for use with centos etc.)
openstack packages, auto install the libguestfs-mount package.

cheers,
Pádraig.

Re: Launching vpn image issue [In reply to]

Thank you all for the responses. There was a problem with my cloudpipe image. So, I recreated it. Now cloudpipe instance launches fine.
However, when I configure, /etc/network/interfaces with br0 as provided in the documentation, I cannot ping or ssh to cloudpipe instance.

http://nova.openstack.org/devref/cloudpipe.html

Any help is appreciated.
Thanks once again,
-vj
