I just converted one of my xen domains running on an x86_64 from ext3 to
xen. That's one partition containing everything, system and data. I must
say, I am content with performance compared to ext3. What I've seen is
that an umount takes quite a while after having written tons of data
(like with bonnie++). With umount I mean: shutdown xen domain, mount
this partition, write data on it, and then umount it and wait up to 1
min for it to complete(!).
The only thing I had to care of around xenU was the xfs module, which
had to be pre-known via ramdisk, so I had no worries being able to boot
the xenU...
mkinitrd /boot/initrd-`uname -r`-xenU.img `uname -r` -v --fstab=/mnt/lvx04/etc/fstab
