Проблемы с QEMU RVM, Libvirt?

Всем Привет!
Ситуация такая:

Есть выделенный сервер с СentOS 6.8
В ней виртуалка с Windows Server 2012R2 "wsvm"
Набор программ такой: Libvirt, QEMU, virt-manager.
Изначально задумывалось пробросить порты (80, 3389, 443) для WS2012R2 наружу

Но при настройке возникла проблема с сетью, при работе из-под Windows, через некоторое время пропадает сеть (No Access Internet)
Т.е DHCP (по умолчанию) по началу дал IP, и все работало.

P.S Извините за портянку такую

настройки таковы:

/etc/libvirt/qemu/wsvm.xml
