libvirt failure when hard rebooting instance

[Dan Prince]

Using the latest version of Nova Folsom (Git Hash b1b0936) I'm seeing this error when trying to soft reboot an instance:

Looks like libvirt-python 0.9.6 (Fedora 16) is too old to use with the latest Folsom libvirt changes.

Only the latest Fedora 17 libvirt has the required virDomain.reset() function.

I'm also facing the same problem on Ubuntu 11.10 (GNU/Linux 3.0.0-12-server x86_64)

When I tried to upgrade I got the following message

libvirt-bin is already the newest version.
libvirt0 is already the newest version.
python-libvirt is already the newest version.

I confirmed that I indeed have latest package : https://launchpad.net/ubuntu/oneiric/amd64/python-libvirt

$ dpkg -l | grep virt
ii libvirt-bin 0.9.2-4ubuntu15.2 the programs for the libvirt library
ii libvirt0 0.9.2-4ubuntu15.2 library for interfacing with different virtualization systems
ii python-libvirt 0.9.2-4ubuntu15.2 libvirt Python bindings

Does that mean Folsom won't support Ubuntu 11.10 ?
