Desktop crashes after resize

Latest response

Hi, All. Maybe, somebody already faced the following issue, or at least could reproduce and confirm my assumptions:

 

 when user doesn't use fullscreen and starts playing with size of virtual desktop window - two things happen:

1. Remote-viewer crashes

2. Virtual desktop crashes, stops, and needs to be started again.

 

In libvirt.log I see the following error (the name of virtual desktop machine is internet1):

In my test environment I use RHEV 6.3 as both  RHEV-Manager and KVM host;

I use CentOS as VDI OS, and users are using Win7 on their workstations. 

 

Any advice would be appreciated.
