Citrix VM Tools - Lost connection with XenCenter


Bit-101

Question

A strange problem occurs when I installing XenServer Tools on VM in XenCenter.

The install begins and suddenly I lost connection with XenCenter console.

Reconnect to Host in XenCenter but slightly after that I lost connection again, reconnecting to host and the same

problem.

Then I forced a shut down VM and then the connection to that host is stable again in XenCenter.

 

Any idea what´s i causing the problem?

Really appreciate your answwer

(We dont use pools)
