Just forwarding this changelog from yesterday. xcs now uses Unix domain sockets in unstable. This was a hot thread a couple months back with strong opinions on both sides and no clear resolution on the list, so I thought some people might like to know the developers'' resolution. This should be good news for those seeking tighter dom0''s, particularly those who

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

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

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
