To answer this part separately... A prerequisite for root-on-ZFS is that the boot loader loads both the kernel and two kernel modules (zfs and solaris) and passes the right info to the kernel to tell it the modules are loaded (this is via bootinfo for x86 EFI and BIOS booting). I'm not familiar enough with the Xen boot process to know if this is possible. Also my current work is EFI only as I had some funny memory allocation issues with the BIOS boot loader. This is hopefully just a simple bug... Cheers, Simon.
