Thread-topic: [Xen-devel] crashes
It looked like everything was okay except for these messages in DOM0:
(file=main.c, line=270) Failed MMU update transferring to DOM1
(file=main.c, line=270) Failed MMU update transferring to DOM1
but then I tried to start another domain and got this:
Using config file /etc/xen/mail2
Error: Internal Server Error
so it looks like something is still wrong somewhere...

Well now, without making any changes I can't get it to break anymore. dammit.
I have done a recompile though, so maybe I had something out of whack.
it's been testing for 6 hours now with no errors. I'll leave it overnight and see what happens.

Strange -- I jsut tried this and it didn't ask me any questions:

iap10 > bk cset -x41051ec1NERNxLF017rAWe7ljBk92w

There's probably some clever way of doing it, but I'd just re
clone it with 'bk clone bk://xen.bkbits.net/xeno-unstable.bk'.
