Re: [Libvir] [PATCH] Allow selection of the NIC model in QEMU/KVM



Quoting "Richard W.M. Jones" <rjones redhat com>:

This patch allows selection of the NIC model for QEMU/KVM domains.
The selection is done by adding a <model/> element to the XML, as in
this example:

    <interface type='user'>
      <mac address='00:16:3e:33:b8:d3'/>
      <model type='ne2k_pci'/>
    </interface>

The model type string is only checked to make sure it's a short
alpha-numeric + underscore, since it seems impractical to extract the
actual list of supported models.

I've found how to get the list of supported models:

pgquiles pravetz:~$ kvm -net nic,model=? -hda ''
Warning: vlan 0 is not connected to host network
qemu: Supported ISA NICs: ne2k_isa
qemu: Supported PCI NICs: i82551 i82557b i82559er ne2k_pci pcnet rtl8139 e1000 virtio


If you choose a supported model then QEMU starts up with this extra
-nic parameter:

  /usr/bin/qemu-kvm -M pc -m 500 -smp 1 -monitor pty \
    -boot c -hda /var/lib/xen/images/rhel51x32kvm.img \
-net nic,macaddr=00:16:3e:33:b8:d3,vlan=0,model=ne2k_pci -net user,vlan=0 \
    -usb -vnc 127.0.0.1:0

If you choose a non-existant model then you get the error:

  libvir: QEMU error : internal error QEMU quit during monitor startup
