Re: [libvirt-users] F20 Virt-Manager with MacVTap not working



The guest was setup through virt-manager. The machine is not configured much after a F20 install (I believe I didn't change any network things)

 Here is the network part:

   <interface type='direct'>
      <mac address='52:54:00:fe:b0:66'/>
      <source dev='em1' mode='bridge'/>
      <target dev='macvtap0'/>

      <alias name='net0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>


and the complete dump:

Hello,
I've setup a VM with default networking (NAT) and this works fine but hosts on my LAN can't get to the VM since it uses NAT.

When I try to set network to use MacVTap with either default or bridged I get no networking for the VM. 
Any hints around this? I would like to have the VM's on the same LAN as my host and other machines. I don't care if the VM host can't reach the guests.

It did work find in F19 but there I believe I had more MacVtap devices to choose from.

I am using macvtap on F20 with no problems. Which device are you selecting to connect the macvtap device to? You should use the physical device that your host uses for network communication. Please send the <interface> section of the output of "virsh $guestname dumpxml" (where $guestname is, of course, the name of the guest with non-working networking).
