Re: [Xen-users] More CCISS driver problems

Well, I figured out this problem.  Does this make sense?

The first command line option for the kernel appears to have been
eaten.  This is the option that specified the root filesystem.  Since
the root filesystem wasn't specified, the filesystem driver wasn't
loaded, hence the inability to mount.  If I specified the root
filesystem twice in a row, then the system boots both with and without
the hypervisor.

So, either due to grub-pc or my not understanding something about xen,
if the hypervisor boots, the first kernel argument appears to be
eaten, but if the kernel boots without the hypervisor, the first
argument is not eaten.  This was confirmed by looking at
/proc/cmdline.
