** Description changed: + ====================================== + impact: qemu-kvm cannot be installed if modprobe of kvm will fail + test case: create a precise container; rm /bin/running-in-container; ln -s /bin/false /bin/running-in-container; apt-get install qemu-kvm + regression potential: if the modprobe failures were due to real errors, kvm may fail later on + ====================================== + Iso 172, 180, 183 Ubuntu (guest) 12.04.04 qemu-kvm fails to install because upstart wont pass. root@node-2:~# apt-get install -f Reading package lists...

It appears that guest might have been passed bad CPU flags and qemu-kvm in host might not be allowing kvm acceleration to load.
