[PVE-User] Proxmox VE 4.2-2, 10Gbit Fibre, No LAN Connection in VM

Hey there,

I'm running Proxmox VE 4.2-2 on a HP DL380 G8.
Yesterday I installed a new 10Gbit HP 560SFP+ Dual Port Fibre NIC.
Which lead me to this bug [0], [1].

But since the card is displayed in my Proxmox Webinterface, I think it
should work at least.


So I configured my KVM Container and installed Windows Server 2012 R2 VM
according to the best practices wiki [2].

After Installation however the NIC in the VM does not receive an IP.
The DL 380 host is directly attached to our coreswitch via fibre channel.

To make sure DHCP is working on the coreswitch port I plugged in some
old 1 GBit SFP modules. Connected it to an equally old 24 port Switch.
And plugged my notebook in the RJ45 port. DHCP works fine there.

So in theory it should work in my VM as well. But for some reason it
doesn't. See screenshot [3]
See my Proxmox Host and VM Setup. [4] & [5].

I tried using OVS Bridge instead of Linux Bridge as suggested in [0]#20,
but that didn't work either.

I'm thankful for any tip or advice you can give me.
