Here's an observation: Two out of the top three hottest [1] Mir bugs are 
Mir failing to start (USC/Unity8) due to insufficient graphics drivers:

Running in a VM:
https://bugs.launchpad.net/mir/+bug/1118903

Running with the Nvidia driver:
https://bugs.launchpad.net/mir/+bug/1553549

Not surprising really that people are trying to use Unity8 and the first 
hurdle they hit should amount to the most popular issues.

Hi,

> https://bugs.launchpad.net/mir/+bug/1118903

Is this really about running mir or unity8 in a VM? Both kvm and vmware
support enough of drm/kms to run mir.
I am not sure how far virtual box is with its drm/kms support. Two years
ago some parts were missing. Maybe
virtual box could also use qxl + spice for that purpose? But back to the
statement, I think there is a bigger problem
with running ubuntu on systems without shader support and lack of cpu to
use llvmpipe to compensate that. Those systems
are likely to have drm support.

regards
Andreas

Yes, bug 1118903 is the catch-all bug for anyone trying to use Mir in an 
unsupported VM, or on bare metal with an unsupported GPU and/or no DRM.

Indeed it seems people hitting bug 1118903 lately are trying to use Mir 
in VirtualBox (even VirtualBox on Windows).

As for KVM and VMware, it seems users of those are getting a bit further 
but also hitting this crash now:

The good news is that we are making some progress on the generic 
solution now though:
