Now (about 1 week testing) i have now issues. Memory hotplug work's fine
(i'm add xen dom0 support for that :)). Live migration does not have any
issues. Xenbus watch work's fine (in some e-mails i send message, that
xenbus wath does not work in my kernel module undex 2.6.32 from jeremy
and 2.6.36 from linus.

Now i have not tested second serial console...

My kernel config , xen section is
CONFIG_XEN=y
CONFIG_XEN_DOM0=y
CONFIG_XEN_PRIVILEGED_GUEST=y
CONFIG_XEN_PVHVM=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=128
CONFIG_XEN_SAVE_RESTORE=y
CONFIG_PCI_XEN=y
CONFIG_XEN_PCIDEV_FRONTEND=y
CONFIG_XEN_BLKDEV_FRONTEND=y
CONFIG_XEN_NETDEV_FRONTEND=y
CONFIG_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
CONFIG_XEN_FBDEV_FRONTEND=y
# Xen driver support
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
CONFIG_XEN_PLATFORM_PCI=y
CONFIG_SWIOTLB_XEN=y

Works fine under Exherbo linux (systemd based init system requires
>=2.6.36 kernel)
