# xe-guest-utilities-git

###Purpose
xe-guest-utilities is an add-on package for the [Xen](https://xenproject.org/developers/teams/xen-hypervisor/) and [xcp-ng](https://xcp-ng.org/) hypervisors. As per [documentation](https://xenproject.org/developers/teams/xen-hypervisor/) these tools:
  - Report extra VM info (that only the Operating system can know, not your underlying hypervisor), like VM IP address, kernel version etc.
  - Communicate with the OS in case of quiesce snapshots (Windows and its VSS)
  - Allow sending signals to the OS (clean reboot, hotplug hardware etc.)
This package provides a service file which can be activated/enabled by systemd to provide these features to your VM running with Xen/xcp-ng.

###Source Code
xe-guest-utilities pulls its sourcecode from the [Xenserver](https://github.com/xenserver/xe-guest-utilities) github repository. The source code requires a [Go development environment](https://golang.org/doc/install) in order to successfully compile the code. This script should automatically download the go-pie package, compile and install the script.
