I've installed a KVM host on Ubuntu 14.04. I've added a networking bridge as br0 and also added the p4p1 network adapter to it.
My problem is now that only the "pcnet" networking guest driver is working well. All the others "e1000", "ne2k_pci", "rtl8139" and "virtio" doens't work. With these drivers I have no network connection and also no PXE boot (Timeout).
But I want to use the virtio driver for performance reasons.
Installed packages: apt-get install qemu-system-x86 qemu-kvm virt-manager lvm2
My bridge configuration:
#brctl show bridge name bridge id STP enabled interfaces br0 8000.002590d4ef56 no p4p1 vnet0 virbr0 8000.000000000000 yes
The vnet0 interface was added by kvm automatically.
My /etc/networking/interfaces File looks like:
auto lo iface lo inet loopback auto br0 iface br0 inet static address 5.101.XXX.XX netmask 255.255.255.0 gateway 5.101.XXX.1 bridge_ports p4p1
Maybe you guys have an good idea :)
Thank you very much.
