I was able to create windows instance and get it working, but the rdp connection to the instance gets disconencted once in while. I had similar issues in linux and it was resolved by turning off tso,gso and gro in the nic cards.

Has any one faced such issue , I have tried tweaking off checksum in windows nic but it was not worth it. Please update me if there is an thing I can try.

Update: I have also tried updating the VirtIO Drives

You can also try to adjust the MTU. Windows doesn't apply the MTU advertised by the DHCP. If you are running with neutron and GRE tunnels, it should be 1454 instead of 1500.

And also try to turn off gro by ethtool -K INTERFACE_NAME gro off. Replace INTERFACE_NAME with adapter, you are using with Openstack
