We’re mostly running XenServer 7.1 CU2 and use the XenServer 7.1.1327 and 7.2.1537 Management Agents (Drivers) in our VDI and RDS workloads.
We have been rolling out uberAgent 5.3.1 to 500+ VM’s with great results. With some of the recent improvements and features of version 6.0.0 (specifically network and GPU) we have been testing this and finding that it’s not happy when installed after the XenServer Management Agent has installed.
The install almost completes and then the VM seems to blue screen/restart when the service starts, which is related to the new drivers in version 6. I’m assuming there is an issue with the XenServer PV Network Device (xennet.sys) driver. We’re running both version 22.214.171.124 and 126.96.36.199 (https://support.citrix.com/article/CTX235403)
Refer to the following screen shot that may help demonstrate what I've tested.
If I modify the uberAgent-64.msi and remove the drivers from the Component table, it installs without blue screening, but obviously it’s not in a working state. I just did this to isolate the issue.
If I modify the uberAgent-64.msi and remove the ServiceControl row from the ServiceControl table, the install works without issue. No blue screens. If I then start the service it will blue screen. If I restart the VM and allow the service to automatically start, it will blue screen.
Happy to provide any further information for troubleshooting and debugging.
