Hi all,

My test environment

Host os=rhel6.1

Guest os = rhel6.1

Libvirt=0.9.8

Kvm hypervisor

I am creating a macvtap interface on host machine at eth0 interface

#ip link show macvtap0

51: macvtap0@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UNKNOWN qlen 500

link/ether 1e:aa:f7:43:7e:3d brd ff:ff:ff:ff:ff:ff

I have made this entry in guest xml file

<interface type='direct'>

<mac address=1e:aa:f7:43:7e:3d’/>

<source dev='eth0' mode='bridge'/>

<model type='virtio'/>

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

</interface>

Now when I start the guest

#virsh start guest

It gives following message

“Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization.

[FAILED]”

Guest eth interface does not create. what is the problem.

Please let me know what else we need to do to make macvtap work on kvm.
