Hello! We tried to move Windows 2003 VM with e1000 driver from Centos 7 which runs qemu-kvm-0.12.1.2-2.491.el6_8.7.x86_64 to Centos 7 with qemu-kvm-ev-2.6.0-28.el7_3.6.1.x86_64 and we got problems- tcp sessions, namely smb connections, randomly drops. We didn't test previous qemu-rhev with this VM, so we don't know how it works in them. Could you tell me is this known problem? Any workaround except switching to virtio? Thank you!
