I tried reproducing this while using trusty on the host and was unable to do so. I also could not reproduce with the trusty kernel (currently 3.12) running with saucy userspace on the host. So as far as I can tell the issue is fixed in 3.12. I took a stab at trying to bisect, but something

As it seemed that starting a 64bit hypervisor (qemu-system-x86_64) from a 32bit user-space running on another 64bit hypervisor has different issues which seem to go back even further, I concentrated on bisecting the case of host running 64bit user-space on a 64bit CPU and the first level guest

Btw, James, this means there is a simple but not very helpful work- around for Saucy: use AMD CPU based hosts. Did not check for 32bit user- space on 1rst level but with 64bit and had no issues. Not very surprising as the regression seems to be in the nested VMX code. But also not very useful when

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

They can be even together. The -nographic removes any emulated graphics card. I am not sure in detail how the cloud images work, but I believe serial line as a console is always on. Depending on which release (in that case I think it is the qemu user-space) the used setup would not work even.

I saw a similar crash when running the prepare script with a Saucy64 host, a Saucy32 1rst and Saucy32 2nd level guest. The 1rst level guest cpu set to core2duo and I also had to replace the qemu-system-x86_64 by qemu (which maps to the same arch). Otherwise the 2nd level guest was not started at

Using a 64bit 1rst level guest seemed better on manual runs but running in loops seemed to have locked up on the third run. Though completely without any messages. I have to look into that next week. I need to run again with qmp enabled. At least this allows to check for the instruction pointer of

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)

Per comment #13, it sounds like this issue is resolved in the 3.11 kernel, which is what Saucy will be rebased to. Does this issue only exist in Saucy, or should the bug be targeted to other releases as well? ** Also affects: linux (Ubuntu Saucy) Importance: High Status: Incomplete **
