Gotcha, I misinterpreted your statement. Yes we are in agreement.

Have you had any further failures after installing qemu-kvm?

Nested on Intel should be much improved in newer kernel versions
(especially with regard to nested ept as the original report seems to
indicate is in use.
So if the original emulation failure is reproducible, I'd suggest
testing on a newer kernel.

Answers to some of your questions:
Can you only get this on one particular host (i.e. hardware type)?
- No as I can repro in KVM
-Is there anything in syslog?
- Nothing relevant
Which packages (dpkg -l | grep qemu)
ii qemu-utils 2.0.0+dfsg-2ubuntu1.6 amd64

Title:

This is a package dependency issue and not a kernel issue. Once
davidpbritton installed 'qemu-kvm' he was able to install using virt-
install just fine.
So overall either the packages davidpbritton was installing weren't
sufficient to use qemu with KVM, or we have a dependency problem in the
apt history.log for packages installed on top of base system. Note that
only the last entry was done by me, the others were done in preparation
of the image:

Basically, I booted a curtain installed maas node with an amd64 trusty
image from maas. Logged in, ran
So I'm not completely sure virtinst should depend on qemu-kvm, since we
assume one can use it without --virt-type=kvm, so my thoughts would be
you should install additional package as necessary to use qemu w/ KVM.
I'll let hallyn comment as well.

I just added qemu-kvm as a dependency for the openstack installer. It is
probably correct in assuming that virtinst shouldn't depend on qemu-kvm
since you can do paravirtualized.

Also please show the results of:
dpkg -l | grep qemu
Does a reboot or a 'rmmod kvm_intel kvm; modprobe kvm kvm_intel' fix
it?
You said earlier (in irc) that 'sudo apt-get install qemu-kvm' fixes it.
Is that still the case?

So adding qemu-kvm fixed the issue with running nested KVM. I think
though the problem still exists on a non nested environment.
I'll get with the user who encountered this and see if I can get some
more logs.
Thanks

David,
Could you attach the collection of:
apport-collect 1387881
Also the output of:
dpkg -l |grep qemu
On the affected NUCs if the problem still persists?
