Hi,
Can you precise what is the difference between using an "e1000" NIC and "e1000e". Because we have network problems with Windows Server 2008. We test KVM under VMware Player with nested virtualization and it's works, but KVM under ESXi 5.1, only Windows Server 2003 and XP works without networking problem, but all new versions of Windows ( We tested 2008 R2 and 2012 ).
We are using KVM with bridging network card.
Regards.
