[Xen-devel] failed startup caused by unpriveledged domain device nodes not present in priviledged domain

I have a gentoo install running as Domain0 which uses a compaq smart array for it's disk storage (/dev/ida/c0d0) because of this, there are no device nodes present for /dev/sdX or /dev/hdX (aside from /dev/hdc for the cdrom). I'm trying to make my unpriviledged domains use lvm volumes with the following configuration:

disk = [ 'phy:fs/ns1,sda1,w', 'phy:fs/ns1_swap,sda2,w' ]

When I try and start the domain, I get the following output:

Using config file "/etc/xen/ns1".
Error: Error creating domain: vbd: Device not found: sda1

If I replace sda1 with hdc it works (except that it now complains about sda2).

This strikes me as odd behaviour, shouldn't the device nodes in the priviledged domains be largely irrelevant for the unpriviledged domains (in the case of vbds at any rate)?

Thanks in advance,
