[PATCH] Use virtio-serial, remove other vmchannel methods.
by Richard W.M. Jones
Notes:
(1) Tis doesn't completely remove legacy serial ports yet. I couldn't
work out how to make the Linux kernel see the virtconsole, so that is
still using a serial port.
(2) The guest network is completely unavailable if you apply this
patch. We will need to add this back, possibly as an optional
feature.

[PATCH] Change to using ext2-based, cached supermin appliance.
by Richard W.M. Jones
This patch changes libguestfs to use the ext2-based appliance, cached
if possible.
I've tested this with the alpha version of febootstrap from here:
http://koji.fedoraproject.org/koji/buildinfo?buildID=191338
and it at least passes the tests.
There are some hacky bits right now:
(1) We add the root -drive option last on the command line, then (in
the initrd) reverse-search through the block devices, mounting the
first one we find. Dan pointed out that we could name the drive using
the qemu '-drive file=..,serial=LIBGUESTFSROOT' option, which would
allow unambiguous identification. However there are other issues with
this.
(2) We take steps to ignore the new device from the point of view of
the user, but I haven't rigorously gone through the whole API to check
that the device is truly hidden everywhere.

virt-p2v converts physical machines to virtual machines. Boot with a
live CD or over the network (PXE) and turn machines into Xen guests.

Proposed new file apis
by Matthew Booth
I've attached a patch to generator.ml for the proposed new file apis.
Note that hread, hpread, hwrite and hpwrite are slightly different to
the apis I proposed previously. I've also added hallocate for good measure.
