XenServer tools do not work
The xe-guest-utilties package does not work with 3.9.2. The package does not correctly detect Alpine as the distro.
# service xe-guest-utilities start
* Detecting Linux distribution version ... [ !! ]
* Starting xe-daemon ... [ ok ]
Although in previous xe-guest-utilties package versions /usr/sbin/xe-linux-distribution had methods to detect Alpine, they have been removed. Patching /usr/sbin/xe-linux-distribution with the old methods allows the script to detect Alpine, but XenServer 7.6 does not see that guest utilities are installed.
