[ubuntu] Xen hang on shutdown

view story

http://ubuntuforums.org – Hi, I'm having an issue with Xen 4.2 running on Ubuntu 12.04. The install is an Ubuntu 12.04-x64 host with two Ubuntu 12.04-x64 guests and one Windows server 2008 R2 guest with the signed PV drivers. I'm using the XL toolkit. I'm suffering an issue where the machine gets stuck at the "Will now reboot" line when the host is rebooted while the guests are still running. 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 (Hardware)
