That's not really ideal for a virtualized environment. Think of a hosting
setup for example. You'd really like to have the "hoster" control dom0, but
have roles that allow a vm sysadmin to control his domain. Console and
power/reset only perhaps, but still some xend access.

I'm not arguing against that. I was just pointing out the difference in
roles needed. I think that will actually be orthagonal to protecting
xend itself. Make it secure first then carefully allow access for roles.
The tools will need to handle this permission I think.
