Hi All ,
I came across weird issue last week. I have two 2008 R2 Hyper V hosts. Each of the hosts have around 15 virtual machines running. One fine day , i found that virtual machines have stopped capture mouse pointer.
everything was running fine day before. I used to access the virtual machines from Hyper V manager. There was no changes nor any reboots. Suddenly virtual machines stopped capturing mouse pointer. Keyboard capture worked.
Say out of 15 virtual machines atleast 10 faced the similar issue. Most of the VM were 2008 R2 and few were 2003. It should be issue of Integration Services component as everything was working fine before.
Only way out for me was reset the virtual machines , which got there issue resolved. Luckily they were DR servers , so i could afford reboot. I also tried to RDP into those virtual servers , still no go.
I did check out the event viewer , especially the Hyper V logs , but couldnt find anything.
