Issue Report

XenServer Tools is unable to report CoreOS' VM IP address to the XenServer host: Permission Denied.

Bug

CoreOS VM's XenServer Tools agent fails to register itself with host XenServer.
This means there is no IP address shown in Networking tab, resulting in inability to enable Docker management (along with any other functionality, when a connection from XenServer to VM is required), due to XenServer being unable to connect to host VM.

Container Linux Version

NAME="Container Linux by CoreOS"
ID=coreos
VERSION=2079.6.0
VERSION_ID=2079.6.0
BUILD_ID=2019-06-11-0821
PRETTY_NAME="Container Linux by CoreOS 2079.6.0 (Rhyolite)"
ANSI_COLOR="38;5;75"
HOME_URL="https://coreos.com/"
BUG_REPORT_URL="https://issues.coreos.com"
COREOS_BOARD="amd64-usr"

Environment

Xenserver 7.2
Updates to E017
Container Management 1.0

Expected Behavior

CoreOS boots
XenServer Tools agent starts - no errors
XenCenter shows 'Virtualization state: Optimized (version 7.2 installed)' in VM's General tab
XenCenter shows IP address(es) related to VM in Networking tab
XenCenter is able to turn on Docker management via an SSH connection

Actual Behavior

CoreOS boots
XenServer Tools agent starts - no errors
XenCenter shows 'Virtualization state: Optimized (version 7.1 installed)' in VM's General tab
XenCenter missing IP address(es) related to VM in Networking tab
XenCenter is not able to turn on Docker management via an SSH connection. Failing due to missing IP address.

Reproduction Steps

1.Boot CoreOS from ISO image with a default cloud-config
2.Open XenCenter, navigate to VM's Networking tab

Is this new with that release or does it also affect older versions?
