Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.16 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Title:
Kernel nested kvm support
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Before we go barking up the tree of the Ubuntu Touch emulator on bare
metal using MAAS and Juju, I wanted to make sure we tried nested kvm.
I heard rumors that this was known not to work well, and sure enough
if I run the touch emulator inside an i386 2G RAM trusty instance on
Canonistack, I get the occasional kernel panic or OOPS.
If it's not something we care to support, that's fine, but getting a
statement from the kernel team to this effect would be helpful.
