I got the panic again last night. This was running a 3.11 kernel for the
host, but of course the 1st and 2nd level guests were still running 3.10
as 3.11 is still in -proposed. So, although it's possible to get a test
run with (3.11, 3.10, 3.10) I really need to try running with (3.11,
3.11, 3.11)
Now that 3.11 is out of proposed, we're seeing a different kernel
failure, starting with
run-parts: executing /etc/kernel/postinst.d/zz-update-grub 3.11.0-2-generic

To recreate:
1) Follow instructions on internal wiki (page
InformationInfrastructure/IS/CanonicalOpenstack) to create a keypair.
2) Create an guest instance:

$ euca-run-instances -k $keyname -t m1.medium
Latest kernel panic (from 2nd-level guest) using following kernel
versions:

1st-level guest: 3.11.0-2-generic
2nd-level guest: 3.11.0-2-generic
** Attachment added: kvm.log
The latest advice for running on Canonistack (kvm guest instance where
nested=Y is to):
- Only run on a 64-bit Canonistack guest instance.
- Modify bin/prepare-testbed and bin/run-adt-test to start the autopkgtest VM
using 'qemu-system-x86_64 -enable-kvm'.
- Have the DEP8 test running inside the
'qemu -serial file:/tmp/kvm.log' Looks like an alternative to 'qemu
-nographic /tmp/kvm.log 21'.
