is there possible to create a 802.1q vlan on top of a macvtap

["alias" <billyway@xxxxxxxxxxx>]

Hi all,

I am trying to set up a vlan between VM on two hosts, both RHEL-6.

I create macvtap on both host by :

ip link add link eth0 name macvt-v0 type macvtap mode vepa

ip link set macvt-v0 up

and then boot guest RHEL-6 VM with the above created macvtap nic, guest network functioning well.can ping each other.

But when I trying to setup vlan between two guests,things go bad...

inside guests:

modprobe 8021q

VM1:

ifconfig eth0.1 192.168.1.1 netmask 255.255.255.0

vconfig eth0.1 1

VM2:

ifconfig eth0.1 192.168.1.2 netmask 255.255.255.0

vconfig eth0.1 1

after the above cmd,

I ping VM2 from VM1,by 

ping 192.168.1.2 -I eth0.1 

nothing response,I am curious is there possible for macvtap to deal with 8021q vlan ?

Thanks for any reply

Best Regards,

Billy
