Unable to create KVM machines.

Whenever I try to create a KVM machine I receive the following error:

Creating machine: machine creation finished Machine creation failed: KVM, got exception You have specified /var/lib/libvirt/images/bionic-server-cloudimg-amd64.img as image which does not exist

However the file clearly exists, and should be world-readable.

➜  mist l /var/lib/libvirt/images
total 880M
drwxrwxrwx 2 root     root     4.0K Jan 27 03:26 .

I can also report this show stopper is still around! - OH Wait! I finally figured out I could use the MIST.io Machine [ Shell >] command button to do a test and I still got the SUDOer password request. So a search discovered this document which made it clearer… https://phpraxis.wordpress.com/2016/09/27/enable-sudo-without-password-in-ubuntudebian/ That the mod to /etc/sudoers file {username} ALL=(ALL) NOPASSWD:ALL

Replace {username} with the account username you set up for your CLOUD object key of course.

It is important to add this line at the end of the file so that the other permissions do not override this directive since they are processed in order

Another 2 symptoms which cleared up as soon as I fixed this were:

1. the server images did not show then did
2. the monitoring auto-install failed many times then just worked

v4.3.0 includes many improvements regarding KVM support.
