Reproduced with following option 1. Without netdev and reproduced with above steps, the issue also occurs 2. Without dataplane and reproduced with above steps, the issue also occurs Does this problem also happen with other Windows server guests, or just Win2012 R2? Do we suspect this is a Windows guest issue or something on the host virt stack. It was filed against qemu-kvm-rhev, so it seems like QE thinks it's the virt stack. Please confirm. Thanks!
