Re: [Xen-devel] Crashing DomU
After removing some things from my .config (of witch PCI support) xen
now seems to boot.
Good
day,
I'm experiencing a crashing domU kernel (during bootup)
A person on IRC redirected me to the devel mailing list as it might
well be a bug.
Below you can find the information about the crash, and versions used.
(Used .config for domU is attached.)
If you have any questions, feel free to ask.
Greetings,
Killian
