[Fedora-xen] DomU always failed: sda1 frontend doesn''t find backend
Hi,
I''ve try many guest image to run side by side with Dom0 (FC6), even the
last
FC6-xen image from jailtime.org but no one succeed.
Note: I manage the xen''s cfg file to point to this kernel:
/boot/vmlinuz-2.6.18-1.2798.fc6xen
Here is a part of what I have in /var/log/xen/xend..log:
