Issue while connecting VDI Desktop via Spice Client through RHEV 3.0

Dear Team,

We have implemented RHEV 3.0 in our environment. Also, Virtual Desktop has been installed with Ubuntu as a OS. When I am trying to connect via spice client installed on my windows desktop machine, i am unable to connect. It gives below errors on hyper visor.

Could you please help me in resolving the issue. Also, let me know whether the procedure followed is correct.

Would appreciate your valuable guidance on the same.

Regards,

Taher Soni
