I have Xen 4.0 (released version), 2.6.32.13 pv_ops, commit 4dd582f,
with this config: http://pastebin.com/5L44xXQj
It works good enough for testing so far, but I haven't use it for
production purposes. There's a bug with blktap2 and xm
block-attach/detach, but it should be fine for normal usage.

Note that RHEL5 needs

CONFIG_SYSFS_DEPRECATED=y
CONFIG_SYSFS_DEPRECATED_V2=y

so I put it on my config. You  won't need it for newer distros.
It boots longer than usual due to /lib/udev/rename_device uses 100%
CPU, but it's still acceptable, and only happens on boot.

I use dom0_mem=2048M. That's mainly because I have a process on dom0
which needs lots of memory (zfs-fuse). I usually set it to around
768M. And no ballooning.
