Offhand, I like it.  However,

We have virDomainDefineXML with no flags, but we have virDomainCreateXML
with flags; maybe the better approach is to add a new creation flag that
says that in addition to starting the domain, we also make it persistent
at the same time.

But if we do that, it would argue that 'virsh create --persistent
blah.xml' is nicer than 'virsh define --start blah.xml', at least in
that the former needs only 1 API call for new libvirt (but falls back to
2 API calls when talking to older libvirt), while the latter always
needs 2 API calls.

Or maybe it means we need to add virDomainDefineXMLFlags().

Anyone else want to throw some paint on the bikeshed on how best to make
the user experience nicer?
