[libvirt-users] vms doesn't coomunicate via network

[daggs]

Greetings,

I have two vms, one is a router and the other one is a client, for some reason, the client vm is unable get ip via dhcp from the router vm.
here are outputs:
vm1.xml:
    <interface type='bridge'>
      <mac address='52:54:00:54:78:be'/>
      <source bridge='virbr0'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/>
    </interface>

router.xml:
    <interface type='bridge'>
      <mac address='52:54:00:f9:bd:fb'/>
      <source bridge='virbr0'/>
      <target dev='vnet1'/>
      <model type='virtio'/>
      <alias name='net1'/>
      <address type='pci' domain='0x0000' bus='0x0a' slot='0x00' function='0x0'/>
    </interface>
