Instant host reboot on game start in Windows guest

Hello
 
I am trying to start "Rust" game on vm. Once I start game my host instantly reboots (dom0 domu, everything). Xenserver logs are empty. crashreports are not generated too. This game is using EasyAntiCheat so I believe it has something to prevent running in vm.
 
I believe it is very important issue because:
1. it makes xen instant crash (ddos of xenserver host - system reboot).
2. this anti cheat product is very popular.
 
it is not expected behavior that domu is able to reboot whole server.
