Greetings all,
I have a host machine that runs a router within a vm.
I want to allow a connection between the host and the guest so the host can connect to the lan provided by the router vm.
I've created a dummy interface with these commands:
$ ip link add ens99-dummy type dummy
$ ip link set ens99-dummy address 52:54:00:1f:d0:ff
this resulted with this output:
$ ifconfig ens99-dummy
ens99-dummy Link encap:Ethernet HWaddr 52:54:00:1F:D0:FF
inet6 addr: fe80::84b5:24ff:fe62:c16d/64 Scope:Link
UP BROADCAST RUNNING NOARP MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:899 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:321727 (314.1 KiB)
in my libvirt's xml file I have this entry:
<interface type='direct'>
<mac address='52:54:00:0c:cb:3e'/>
<source dev='ens99-dummy' mode='private'/>
<target dev='macvtap0'/>
<model type='e1000'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x02' slot='0x01' function='0x0'/>
</interface>
after the vm is up, I see the adapter in the vm and the host has one more entry:
$ ifconfig macvtap0
macvtap0 Link encap:Ethernet HWaddr 52:54:00:0C:CB:3E
inet6 addr: fe80::5054:ff:fe0c:cb3e/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:889 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:500
RX bytes:0 (0.0 B) TX bytes:320523 (313.0 KiB)
but when I try to request ip via dhcp from both macvtap0 and ens99-dummy I don't get any.
any idea why?
