There must be log entries about what stops the systems to restart the VM's. Can you post your logs?
I wasn't sure which logs you needed when I exported the system logs, so I posted the var\log directory. I did a fresh restart before taking the logs so you shouldn't have to scroll around too much. I'm not sure where to even start when exploring all the log files. Please let me know what you find.
Thanks,
Chase

From the logs it looks like you are running the host in a cluster!?
From http://www.vmware.com/pdf/vsphere4/r40/vsp_40_availability.pdf (page 21)
NOTE The Virtual Machine Startup and Shutdown (automatic startup) feature is disabled for all virtual
machines residing on hosts that are in (or moved into) a VMware HA cluster. Automatic startup is not
supported when used with VMware HA.

Please check this :-
If your VM is failing to start, and libvirt isn't returning a helpful error message, you can find more info in the log files. For qemu/kvm, this is /var/log/libvirt/qemu/$your-vm-name.log. This will show generated qemu command line, and any error output qemu throws. Certain versions of libvirt weren't good at returning this info to the user, so there may be a fixable error here, like a missing storage file.
If you can't determine anything to fix, please report a bug
Or else please refer to the links below :- http://support.citrix.com/proddocs/topic/xenapp6-w2k8/xenapp6-w2k8-readme.html

Unfortunately, reporting a bug right now isn't much of an option for me right now. From the logs I posted do they show anything? I'm still having a lot of trouble getting to the root of this.
