Thanks Daviey. confirmed, with quantal-proposed I get crw-rw---- 1 root kvm 10, 232 May 17 15:43 /dev/kvm
** Description changed: When qemu-system gets installed, the newly installed udev rule causes /dev/kvm to gets chgrpd to kvm and its mode to get set to g+rw. However, because /dev/kvm was tagged with ACL previously, there is a group:: acl on /dev/kvm which does not get removed. Therefore /dev/kvm is g+rw in the file mode, but the acl denies group read/write access. After a reboot all is fine. I have not seen a clean way to have udev remove that acl, and there is no reason for it. So please update the 70-udev-acl.rules file to set MODE=0660 on /dev/kvm ================ SRU Justification 1. Impact: when qemu-kvm is first installed, /dev/kvm is not owned by group kvm (until subsequent reboot). This prevents libvirt from using kvm until a reboot. 2. Development fix: add group kvm during preinst. (this was done in precise, but accidentally dropped in a merge from debian in quantal) 3. Stable fix: same as development fix - 4. Test case: Create a new quantal vm. sudo apt-get install qemu-kvm. ls -l /dev/kvm, check that it is owned by group kvm. + 4. Test case: Create a new quantal vm. sudo apt-get install qemu-kvm. ls -l /dev/kvm, check that it is owned by group kvm. Note if you've install qemu-kvm previously, purging it is not enough before retesting - you must also remove the kvm group entry. 5.
