I'm running 3.4.2 xen with a 2.6.27 old-style dom0, and a 2.6.33.1 pv_ops 
guest. I'd like to get self-ballooning to work, but there is no balloon entry 
in /proc/xen.

I mounted the xenfs as /proc/xen (although I thought that the 
CONFIG_XEN_COMPAT_XENFS option was supposed to populate this directory 
automatically). All I have in there is capabilities and xenbus.

Here's my XEN related kernel config variables

CONFIG_XEN=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=32
CONFIG_XEN_SAVE_RESTORE=y
# CONFIG_XEN_DEBUG_FS is not set
CONFIG_XEN_BLKDEV_FRONTEND=y
CONFIG_NETXEN_NIC=m
CONFIG_XEN_NETDEV_FRONTEND=y
CONFIG_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
CONFIG_XEN_FBDEV_FRONTEND=y
CONFIG_XEN_BALLOON=y
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=y
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
