Since Ubuntu 11.10 use a new kernel, it's very difficult to have a decent support for virtualization.

VirtualBox doesn't support guest additions for ubuntu 11.10, so I can't copy to and from my ubuntu desktop and windows, which I absolutely require, plus FreeBSD seems not to be able to use DHCP without guest additions.

Virt-manager instead gives an error on launch:

Unable to open a connection to the libvirt management daemon.

Libvirt URI is: qemu:///system

Verify that:
 - The 'libvirt-bin' package is installed
 - The 'libvirtd' daemon has been started
 - You are member of the 'libvirtd' group

libvirtError: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Permission denied

The problem is solved by running virt-manager as root, but I don't like that. How do I change permissions to run Virt-Manager as user?

Is there a way to install guest additions on Ubuntu 11.10?
