Hi, good job, no more adding of useless options to virsh :)

I am just wondering about one thing:

This changes the password for the first graphics only, but how to
change it for particular one or all of them together?

[...]

I tried combining it with this ^^ example and I ended up with this
weird diff:

 python2 virt-xml ipa --edit --graphics all,password=foo --print-diff

What's the proper way to do that or is this supposed to work?  If the
latter is the case, I'll be happy to find the place and fix it, but I
rather ask at first ;)

And one off-topic question; since we have libvirt bindings for both
current major python versions, is anyone working on the transition (or
is it even worth it) to change to python3 or even to some compatible
mid-point between these two?

What would you say to a suggestion of changing our shebang in headers
from '/usr/bin/python' to '/usr/bin/env python2'?  Because if I have
python3 set as default, none of the commands work and it looks like
that's the last compatible thing to do for me to be able to stick with
python3 as default.

Have a nice day,
Martin
