Attached is an updated patch providing some support for HVM guests.
I
have tested listing info on running guests and creating guests. cdrom
support for HVM guests still needs some work, as does graphics options.
Guests using graphics type 'sdl' still need some work. Using type 'vnc'
is functional, but you must then manually use e.g. "vncviewer
localhost:<dom_id>" to view.
Okay, I have been looking at it in the last couple of days
I have changed the XML description slightly in the os part:
- instead stating that hvmloader is a kernel, well I used a
<loader>/usr/lib/xen/boot/hvmloader</loader>
loader tag intead, contrary to the non HVM version the kernel
doesn't point to a kernel file, so better rename to what it actually is
- second the device_model is really a device emulator, better placed
in the <devices> section so it is moved there as
<emulator>/usr/lib/xen/bin/qemu-dm</emulator>
I have made changes to the XML conversion code to reflect this, I will commit
whithin one hour or two. Attached is one example of the XML for HVM.
I've also included a patch that backs out some optimizations done
xend_internal.c. There is a bug in xend (from testing - I think Anthony
fixed it and patch got applied to unstable) that does not close the
connection after initial create op causing libvirt to block
indefinitely. Backing out the optimizations allowed me to use the hvm
patch on _testing branch of xen. I've included it for anyone else that
may want to experiment with the hvm patch on _testing xen.
Okay I applied it, it is clearly identified and we can revert it later,
more likely this current code will die slowly when converted to XML-RPC.
Finally, the attached archive contains: 1. a sample xml input file
for
hvm guest, 2. corresponding s-expr sent to xend, and 3. s-expr returned
from xend when getting info on the running guest.
Thanks, that helped a lot :-)
