Which version of Xen are you using? I've just tried with xen-unstable
and it works perfectly:

/dev/xvda1 on / type ext4 (rw,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)

And I don't see any relevant commits between 4.1 and current that have
touched pygrub ext4 support. The commit that added ext4 support to
pygrub is this:

http://xenbits.xensource.com/hg/xen-unstable.hg/rev/c6ee21dca848

And it's already present in 3.4, so unless you are using 3.3, you should
be fine.
