I am setting up Xen for the first time and have run into a problem.
My system was initially setup with Fedora Core 4.
I was able to successfully create a File-backed VBD.
When I boot the domain,I get an error message that is listed at the end of
the below boot messages. I suspect the problem is casued by my fstab.
However,
I am not sure how it should be configured. Fstab listed also.
Any pointers will be greately appreciated.
xm create -c dommain2 vmid=2
Using config file "/etc/xen/dommain2".
