Title:
kvm_intel (nested) module will not load [Input/output error]
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have 2 different systems, both are kvm instances themselves, both running
vivid.
One of them has /dev/kvm and kvm working fine (well, fine-ish bug 1413540).
The other will not load the kvm_intel module.
