Restarting a guest from the UIVM causes the VM to shutdown.
1. Start a guest
2. Go to the UIVM, details of guest, then click on the Reboot Icon.
With guest tools installed and the guests in legacy mode, restart appears to work properly for Win 10 1809 and 1803
Reboot icon doesn't appear for guests without tools installed so the non-tools case is void. UEFI guests with tools experience https://openxt.atlassian.net/browse/OXT-1572, so that's not really testable either. I also can't repro for legacy Win10 guests with tools installed.

Rebooting works as intended with guest tools installed. Verified that issue was only when trying to reboot a guest without tools installed after manually activating the reboot button from within the guest details.
