Now that I look closer at this patch, I realize I accidentally squashed
together two changes: the XEN removal was supposed to be its own patch. I'll
respin after review comes in

Did your follow-up comment mean to imply this would be done separately
too or just the qemu_command.c change?

I guess I see video default'ing to VIR_DOMAIN_VIDEO_TYPE_CIRRUS and
changing based on the presence of various qualifiers, but this seems to
force a specific type based on virtType for virtType == VIRT_XEN that
would seemingly be lost. What is actually on the command line I didn't
chase down...

Still the qemu_parse_command code isn't exactly highly used and I think
as long as it can be explained why there's not need to special case
VIRT_XEN any more perhaps in the commit message, then you've got my:

Thanks for the review and sorry for the delayed response. I split out the xen
changes into their own commit with this message:

    qemu: Remove remnants of xenner support

    Both of these are dead code: qemu_command.c explicitly rejects
    VIRT_XEN earlier in the call chain, and qemu_parse_command.c
    will never set VIRT_XEN anymore

I pushed it along with patch 1, 2, and 4, since patch 3 is independent and has
some comments

Thanks,
Cole
