Re: [Xen-users] supported distributions

[Mark Porter <mark@xxxxxxxxxxxxxxxx>]

If  you used the xen installer, it installed a kernel with very limited 
support for block devices. It looks like you are using at least a SCSI 
HBA or maybe even a RAID controller. The driver for this interface is 
probably not in the default kernel. Most distributions either install a 
kernel with the driver for your hardware built-in or  an initial ram 
disk image with the driver.
The easiest solution is to
   download the source, and expand the xen-2.0 directory
   cd to the xen-2.0 directory and run "make world"
   cd into the linux-2.6.11-xen0 directory and run "make ARCH=xen 
xconfig" (or menuconfig if you don't have X)
   build whatever drivers you need  for the hard drives into the 
kernel, make modules for everything else (usb support, other 
filesystems, network cards, etc)
   cd ../ to the xen-2.0 directory
   run "make install"
  
That should build and install your custom kernel.
Good luck,
Mark
