i've installed 2009.06 as DomU on a openSUSE 11.1 x86_64 Dom0.  no
apparent glitches or errors -- with the pre-reboot, install step.

prior to the 1st step reboot, in Dom0, i've cp'd the zfs-aware
kernel/ramdisk from the just-installed guest,

        from, Guest: /tmp/root/platform/i86xpv/kernel/amd64/unix
        to, Dom0:    /home/xen/kernel.opensolaris

        from, Guest: /tmp/root/platform/i86pc/amd64/boot_archive
        to, Dom0:    /home/xen/ramdisk.opensolaris

the next-step, run-time xen config i'm attempting to use is,

cat osol.cfg
        name         = 'nas'
        kernel       = '/home/xen/kernel.opensolaris'
        ramdisk      = '/home/xen/ramdisk.opensolaris'
        extra        = '/platform/i86xpv/kernel/amd64/unix -B
zfs-bootfs=rpool/ROOT/opensolaris,bootpath=/xpvd/x...@51712:a'
        disk         = [ 'phy:/dev/vg01/vm_solaris,xvda,w' ]
        boot         = "cd"
        vif          = [ 'bridge=br05' ]
        memory       = 1024
        on_shutdown  = 'destroy'
        on_reboot    = 'destroy'
        on_crash     = 'destroy'

@

        xm create -c /home/xen/osol.cfg

it rerutns,

at naive glance, given the "Cannot mount root ...", it _looks_ like a
zfs-support issue ... ?

have i misconfigured, or is there a problem at hand ?

thanks.
