As per my work experiance, XENServer is very much stable product. You will get very less issues if you done proper CPU/Memory/storage scaling for all VM's.

If you faced any issue related to VM like any VM get hanged in reboot or stuck at any state then you can run "xe-toolstack-restart" in xenserver console to resolve it. It is really good command which help to resolved many issues related to xenserver.

Below are the some command which will help you in monitoring.
