There is a race condition between domain_create_ring() and the removal of the do mU entry from xenstore. If the removal of the domU entry from xenstore comes lat er than the first xs_gather() call in domain_create_ring(), it will go on and bi nd the evtchn port to the dying domU, which will cause below error message: (XEN) (file=event_channel.c, line=144) EVTCHNOP failure: domain 0, error -22, li ne 144 Signed-off-by: Max Zhen <max.zhen@sun.com> diff -r c682ae7a1722 -r db465ec...

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
