Hi,
I have installed Xen-4.1.2 on Fedora8 and it works well.
However, it doesn't work recently. The verbose error information and xend
log is provided. I compiled the Xen, but it doesn't work.
Any suggestion on this error is appreciated. Thank you very much in advance.

Please use a more recent version of Fedora and Xen. Say Fedora 19.

Thank you for your reply.
Maybe it works for Xen-4.1.2 on recent version of Fedora. However, I did
some work on the network backend driver on Dom0(2.6.18.8-linux-xen, it's
compiled on fedora8) based on Xen-4.1.2. It's different to port the to
recent version of Fedora.
Thank you all the same.
