I've cloned xen-unstable about 1.5 hr ago , by some reasons changes
had not been applied to  /usr/src/xen-unstable.hg/tools/ioemu-remote/hw/pass-through.c .

PV DomUs for F10,SNV_106,Interpid Server (via debootstrap),
OpenSuse 11.1 may be installed ( via remote VNC connection, even
utilizing vfb ) and work pretty stable at Xen Unstable Dom0 ( kernel 2.6.29-rc5  ).

HVM DomUs failed at startup . Nothing listen at localhost:5900.

No, it's just code cleanup for PCI passthrough, which is for passing
PCI devices through to guests. If you are not doing PCI passthrough -
ie, most ordinary HVM guests - then these changes will not affect you.

In this case, just now. All changes that we make to xen-unstable,
including the qemu-xen-unstable subsidiary tree, go through an
automated build-and-test. Only versions which pass the (fairly
rudimentary) tests make it through to the main trees.

The pre-testing trees (called `staging') are also available and
published but not the `usual' case.

Yes. You can change this by setting the CONFIG_QEMU make variable, eg
in a file `.config' in the xen-unstable.hg top level.

These messages are not very surprising. Is it working ?
