Problems with a snappy tour

[Tom Vaughan]

Hi,

I followed the steps in the "Launch Snappy locally with KVM on Linux"
section on http://www.ubuntu.com/cloud/tools/snappy. Then I ran the
steps in the "A snappy tour of Ubuntu Core!" section on
http://www.ubuntu.com/cloud/tools/snappy. Sorry, I don't see a way to
link directly to these sections. I ran into a few problems. Please see
below.

kvm is running just fine, no errors.

This is on a 64-bit version of 14.10. I am running with LUKS encrypted
root partition and an ecryptfs encrypted home directory, if that's
relevant.

Thanks.

-Tom
