disp-vms were great - if they worked.

[haaber]

The DispVM's make me crazy. Last week (with your generous help) finally
dispVM with debian template worked. Now --without any change that I am
aware of-- it does again not. I tried to start it within dom0 - that
way I get a max of error messages. ("the DVM savefile creation failed"
is kind of unspecific).

So, once again, it is libvirt / virsh. But what is it this time?? Sigh
of despair! Thank you for helping once more.

See if you already have a `debian-8-dvm` vm running (just with no
windows visible).

You can enable "View->Show/Hide Internal VMs" (internal, not just
inactive) in qubes-manager to see it if so.

(or use qvm-ls & qvm-shutdown)

[Nick Darren]

in 'dom0', you can check it using:

$ virsh -c xen:/// list

then 'undefine' the dvm template as shown above and try again after that.

$ virsh -c xen:/// undefine debian-8-dvm

Jean Quellets hint qvm-ls & qvm-shutdown was not applicable, nothing was
running that I could have shut down...

The list contained nothing important to mention here, but the undefine &
retry command worked. Thanks!

That is a strange command to memorise just to start a disp-vm :)) Bernhard
