Description

Multiple mouse clicks in VM console running on XenServer in PV mode results in console session disconnect with following text:
"Access is denied for the console session. Please close the window and retry again".
Problem could not be reproduced for VMs running in HVM mode and does not happen if mouse is not used for VMs running in PV mode.

Console System VM /var/log/cloud.log seems to indicate root cause of this issue:
