Open Stack

I see the following related packages on my VM:

libguestfs.x86_64                      1:1.16.34-2.el6
python-libguestfs.x86_64               1:1.16.34-2.el6

But neither were able to be updated. Any other thoughts?

Thanks,
Mark

from the exception we know an argument is not supported by python guestfs ,, I tested this in ubuntu 13.10, it works well,

ii  libguestfs0:amd64                         1:1.22.4-1ubuntu1                                 amd64        guest disk image management system - shared library

you can try to upgrade the related packages.

Following up, when I attempt to launch a medium flavor image, here's the output in the nova scheduler log file:

Subject: [nova] No valid host found

Hi everyone,

Whenever I try to launch an image instance beyond 'micro' (anything that has more than 0 GB disk space) I get the "no valid host found" error, even though my disk has 100+ GB of space, even displayed in the dashboard.

The error in the nova scheduler says "Flavor's disk is too small for requested image." Any suggestions as to what I should try or what may be happening?

FYI I'm running a DevStack based install of OpenStack.

Thanks,
Mark
