Hi,
Are you using xl or xm?
I'm using xl on Xen 4.2 on Ubuntu 12.04 64-bit and am suffering from a similar issue (machine getting stuck at the "Will now reboot" line), except, if I shut all the guests down using "xl shutdown" the guests do terminate properly (after about 30 seconds). If I then do a reboot on the host, it completes cleanly.
If I don't shutdown the guests, I have observed some possibly strange behaviour during the host shutdown before it hangs. In the shutdown progress I see:
> Stopping xenconsoled
> WARNING not stopping xenstored as it cannot be restarted
> Shutting down Xen domains: Linuxguest1 (shut) Linuxguest1 (shut) Linuxguest2 (shut) Linuxguest2 (shut) Windowsguest (shut) SHUTDOWN_ALL * [done]
The things I think are strange are that the two Linux guests are listed twice in the shutdown line despite each only being running once and that it blows straight through the line saying "[done]" without waiting for the guests to terminate. It then unmounts the discs before all the guests have wrapped up so they never do terminate. If I leave it, I get repeated kernel warnings that the reboot process has been delayed for more than 120 seconds. I waited over 300 seconds (the time specified in XENDOMAINS_STOP_MAXWAIT) but it doesn't time out and recover.
My xendomains file contains:
XENDOMAINS_SYSRQ=""
XENDOMAINS_USLEEP=100000
XENDOMAINS_CREATE_USLEEP=5000000
XENDOMAINS_MIGRATE=""
XENDOMAINS_SAVE=
XENDOMAINS_SHUTDOWN="--halt --wait"
XENDOMAINS_SHUTDOWN_ALL="--all --halt --wait"
XENDOMAINS_RESTORE=false
XENDOMAINS_AUTO=/etc/xen/auto
XENDOMAINS_AUTO_ONLY=false
XENDOMAINS_STOP_MAXWAIT=300
I disabled the save and restore options because I am using PCI passthrough and trying to restore a saved VM caused the machine to crash at boot.
I'm wondering if these problems are something to do with me using xl as most of the examples and references to the settings mention xm.
Do you have any suggestions why this hanging or why the "--wait" in xendomains doesn't seem to be having any effect please?
Thanks,
Paul.

I installed signed pv drivers for all my windows hvm. When I issue xl reboot or shutdown I see windows shutdown and freeze on shutdown screen. Some
times it black screen with a cursor. The vnc worked months ago with unstable 4.2 but stable 4.2 does not work nor unstable 4.3
I had recompiled xen 4.3 with spice and that works perfectly I guess as bonus I can redirect usb devices.

My Windows HVM guest wouldn't shut down on command from the dom0 until I installed the open source PV drivers. It now sees ACPI power events when the host wants it to shut down.
If you do an "xl shutdown vm_name" (assuming you are using xl) while the VNC console is open, do you see Windows shut down?
I'm fighting a slightly different issue to do with shut downs. Do you have event handlers in the guest Config to destroy the guest if it or xend shut down?
