I'm finally getting to play with Xen, and my plan is to stick all my PCI

Hi Sten,
what I would do is put the domU kernel straight into the boot
loader (grub) and test wether it works without xen.
Sincerely,
Jan.
Attempting to boot my xenU kernel straight from GRUB results in a
"unsupported or invalid executable" message; this occurs with both XenU
and Xen0 kernels, and I assume it's expected behavior since the kernels
are compiled for the Xen architecture rather than i386. Feel free to
beat me with a trout if I'm wrong on this.
I went back and tried using my XenU kernel as dom0, which promptly
failed with "not syncing: VFS". I built an initrd image for the XenU
kernel, and then I was able to boot with the XenU kernel as dom0; I got
to a command prompt and could log in. I bounced back into my original
Xen0 kernel, added a "ramdisk = " line to my xenu config file, re-ran xm
create -c myfile, and, again, it sat and did nothing.
Maybe the problem isn't the kernel after all; I've tried two types of
VBDs, file-backed and LVM. I created an LVM image with debootstrap, and
created the file-backed VBD by dd'ing the contents of my LV into a file.
I also tried using the process for creating a file-backed VBD in the Xen
user guide verbatim, and same result. Is there a more foolproof way of
creating a VBD I could try?
Thanks!
