Title:
Kernel nested kvm support
Status in “linux” package in Ubuntu:
Confirmed
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.
