[Xen-devel] Kernel panic - not syncing : Question from Xen newbie
Hi I''m new to Xen and just installed using the instructions from the website. I''m having Fedora Core Linux distribution. The CPU is a Intel P4 2.4 GHz processor. Xen installation on dom0 works properly. Then, I want to create a new domain using the simple example shown in the Xen documentation website. I''m getting a kernel panic error, and can''t figure out how to proceed. I''ve gone over the mailing list archive, but could''nt find a solution for this. Any pointer or help is greatly appreciated. Here''s the ouput when I try to create a new domain: ----BEGIN---- # xm create -c /etc/xen/xmexample1 vmid=1 Using config file "/etc/xen/xmexample1".
