I have been experimenting with starting qemu manually with the same 
commandline that libvirt would use, and I have found that if I leave out the
"-nodefaults" parameter, the VM will start up reliably again.

What are the reasons for libvirt to use that parameter in the first place?

What bad things might happen if I just leave it out all the time (or patch my 
local copy of libvirt that way)?
