Hi all, this is the long awaited patch series to add xen device model support in qemu; the main author is Anthony Perard. Developing this series we tried to come up with the cleanest possible solution from the qemu point of view, limiting the amount of changes to common code as much as possible. The end result still requires a couple of hooks in piix_pci but overall the impact should be very

This patch series makes suspend support in qemu alot more useful. Right now the guest can put itself into s3, but qemu will wakeup the guest instantly. With this patch series applied the guest will stay suspended instead and there are a few events which can kick the guest out of suspend state: A monitor command, ps/2 input, serial input, rtc. Not much yet, but it''s a start with the

The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/or parallel impls of the same concepts, and
