Did you set the zpool's default "bootfs" property? If you didn't
(or you have multiple zfs boot filesystems on the pool),
you can also set it with the "bootfs" grub command, like this:
title Solaris Express Community Edition snv_66 X86 (b66, Xen dom0)
root (,0,g)
bootfs files/s11-root-xen
kernel$ /boot/$ISADIR/xen.gz
module$ /platform/i86xpv/kernel/$ISADIR/unix
/platform/i86xpv/kernel/$ISADIR/unix -B $ZFS-BOOTFS -vk
module$ /platform/i86pc/$ISADIR/boot_archive

What is the exact error message? Is it from grub, or
from the Solaris kernel?

Note that you need grub from snv_75 or newer, otherwise
you can't boot xen from a zfs filesystem; this is bug 6584697,
Synopsis: Can't boot Xen / Solaris dom0 if root is using ZFS
