Xen DomU hanging at "Checking for hardware changes"? Check your xenconsoled in your Dom0.

Dear self,
This is the second time this has happened to me, so I'm writing to you, my future self, a quick note so you don't have to relearn this a second time.

If when restarting a DomU, the DomU hangs at "Checking for hardware changes", check on the Dom0 to see if your xenconsoled has died. If so, restart it (ie. /usr/sbin/xenconsoled) and it should immediately fix the hanging DomUs.

This guy has a blog post with same issue, but I don't think he ever figured it out because he took a scorched-earth route to fix the problem. However, it does have a nice screen shot of what the hung DomU looks like.

Yours truely,
