I'm attempting to run Arch Linux as a guest/domu on my Xen Dom0. When I try to install Arch doesn't see any hardrives.. though I have a virtual hard disk mounted to the guest. Any one had this problem or know how I might get Arch Linux to see my vbd?

If you boot the Arch installer and change to a free terminal what does 'fdisk -l' show and what does and 'dmesg' say?

I'll respond to this proper as soon as I get home from work. LONG HOURS today! Thanks for the response.

Blarg .. having a weird problem where if i reboot the system from within the console on the install it blows up the vm and wont even see the iso as a bootable drive until i delete / recreate the vm. The only thing I've managed to find is that the last 2 entries of fdisk-l are
Disk/mapper/arch_lib-modules: 100MB, ..... Disk identifier: 0x00000
Disk /dev/mapper/arch)lib-modules doesn't contain a valid partition table

Disk/mapper/arch_usr-share: 100MB, ..... Disk identifier: 0x00000
Disk /dev/mapper/arch_usr-share doesn't contain a valid partition table

I tried using |more to see the rest of the entires but no luck.

I believe I found the issue. I need to install some modules on Xen .. or so it says on the ArchWiki.. Says I need xen-blkback for I/O pass through or Arch wont see my disk. Also says I need xen-netback. I'm guessing these are additions to the kernel. I'm trying to figure out how to get them installed.
