Description Jeremy Katz 2007-04-17 13:19:49 EDT
We're just using the default (ne2k-pci) from qemu as the nic type...  this is
probably _not_ what we actually want, but I could see the argument that we
should just change the default nic model in qemu/kvm themselves rather than
having virt-manager specifying something.  If we go the route of changing the
default with qemu, then we also can get the improvement of switching to the
eepro sooner as well
Comment 1 Daniel Berrange 2007-04-17 14:47:06 EDT
Libvirt does not have a way to specify the NIC model in the virtual network
interface config, however, we can easily add such an attribute & thus let
virt-manager choose alternate NIC model. Quickest option is to just change
libvirt to force use of rtl8139 when spawning QEMU.
Comment 2 Jeremy Katz 2007-04-17 15:33:10 EDT
The question is does it really make sense to specify it?  It'll add more
dependencies that we need to check based on version of qemu to know the "best".

So being able to specify it is reasonable, but the more I think about it, the
more I think we should just change the defaults in qemu/kvm to be the
better/right thing.

FWIW, the patch to change the default is tiny and done for kvm-19-1.

Fixed in KVM per #3.
