CLOUDSTACK-143 vcpu hotplug is used whenever the number of vcpus are increased or decreased while the vm is online. so far this is never done in CloudStack for system vms. Also, no evidence that this file is copied to /etc/udev/rules.d where it would be needed

CLOUDSTACK-144 xe-linux-distribution.init is used to communicate the distribution information to the xe toolset in dom0. No evidence that this file is copied to /etc/init.d where it would be needed. The right way to do it would be to install the xe-guest-utilities deb package from the xs-tools ISO distributed by Citrix XenServer
