Hi.
I guess the best way to proceed here is to explain a little bit how do you
want your networking setup. You csn have a subnet for VM's and Hypervisor,
you can have NAT, you can have bridge. Do you want to leave IP addresses
and routes to Operating System or do you prefer to leave it to KVM?
Regards.

Hi,****
** **
If I have these fragments in a domain definition, the guest will start
with "eth0"****
assigned by dhcp to an address on my lan. Things seem to work according
to the documentation****
I can find.****
** **
<network>****
<name>direct-macvtap</name>****
<forward mode='bridge'>****
<interface dev='eth0' />****
</forward>****
</network>****
<devices>****
<interface type='direct'>****
<mac address='00:15:17:A6:BC:C9' />****
<source dev='eth0' mode='bridge' /> ****
<model type='virtio' />****
</interface>****
</devices>****
** **
I don't understand the <network> part here. It doesn't seem to be
documented. I inherited these pieces****
so I do not know why they are as they are.****
** **
If, instead, I have the following, the guest comes up with no network
interface at all****
(except lo). On the host, interfaces vnet0 and virbr0 exist and virbr0 is
192.168.122.1.****
** **
<devices>****
<interface type='network'>****
<source network='default'/> ****
</interface>****
</devices>****
** **
Adding in****
** **
<model type='virtio' />****
** **
makes it start with "eth0", but no address has been assigned. I can
manually do that and then****
I can communicate with the host but it's kind of a pain to add the address
and routing manually.****
Oddly enough, though, ping from host to guest works normally, but ping
guest to host seems to succeed once****
then hang (with no timeout).****
** **
It is not at all obvious to me how virtio magically creates eth0.****
** **
Am I doing something wrong, here? And, if anyone could advise how to use
openvswitch****
I'd appreciate it. I've seen adding****
** **
<virtualport type='openvswitch/>****
** **
might be enough, presumably with an appropriate name for the source
network.****
