Applied the latest pushed updated to production, no major issues.
The only thing to note is my backup XCP config failed Sunday, some time post the patches being applied. The error was the Body Timeout Error. This morning the backup ran without issues. Not sure why, but it wasn't a big deal and it working now. So not sure tied in with patching or not.
I figured out how to get serial and GPU PCIe devices added.
Serial must be done via CLI at the server console. When you access the VM properties with Orchestra you'll see the graphics card has been detached. You can add it back via Attach PCI then both devices will show up as attached.
