I wonder why xen 4.2 unstabl does not upgrade it qemu to git://
git.qemu.org/qemu.git.
It attempted to compile arch linux package xen-4.2 and changed qemu and I
mode Makefile but I gt errors when qemu is configured.
Is anyone using newer qemu for better sound suport and etc.
There is patch for newer version of qemu. Makefile needs to be patchea as
xen-setup is missing.
