service xencommons does not exist

Installed Alpine 2.6.3 sys to use it as a Xen host

Followed this wiki to install Xen Dom0 http://wiki.alpinelinux.org/wiki/Xen_Dom0
Everything works upto this part:

rc-update add xencommons

with error:

rc-update: service 'xencommons' does not exist

Searched around for xencommons - not sure exactly what this is. Tried:

apk add xencommon

ERROR: 1 unsatisfiable dependencies
world: xencommons

The boot loader already has en entry for Xen. After login it says:

OpenRC 0.11.8.73d56a6 is starting up Linux 3.10.5-1-grsec (x86_64) [XENU]

So I assume I am logged into a Xen kernel but can't load xl list

libxl: error: libxl.c:87:libxl_ctx_alloc: Is xenstore daemon running?

As a guees I tried xenstored but that gives error

xc: error: Could not obtain a handle or priveledged command interface (2 = No such file or directory): Internal error

Any ideas to get xl list and rc-update add xencommons working?

Finally I tried apk cache sync but that errors with ERROR: Package cache is not installed

Thankyou.
