Hello,
I'm trying to use macvtap on Debian Wheezy.
Actually, I've installed a recent version of libvirt and qemu from
Jessie, using wheezy-backports.
$ virsh version
Compiled against library: libvirt 1.2.1
Using library: libvirt 1.2.1
Using API: QEMU 1.2.1
Running hypervisor: QEMU 1.7.0
I'm trying to configure a macvtap interface like this:
<interface type='direct'>
<mac address='52:54:00:7b:05:cd'/>
<source dev='eth1' mode='passthrough'/>
<model type='rtl8139'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08'
function='0x0'/>
</interface>
The interface eth1 is used exclusively by this VM, so as far as I
understand, mode 'passthrough' is enough since I'd like to "plug" the VM
straight onto a public static IP.
On my /etc/networks/interfaces, I have this:
# start :: define eth1
iface eth1 inet manual
# end :: define eth1
It does not matter whether eth1 is up or down, when I try to start the
VM, I get the following error:
Error starting domain: Cannot create macvlan devices on this
platform: Function not implemented
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 45,
in cb_wrapper
callback(asyncjob, *args, **kwargs)
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 66,
in tmpcb
callback(*args, **kwargs)
File "/usr/share/virt-manager/virtManager/domain.py", line 1114,
in startup
self._backend.create()
File "/usr/lib/python2.7/dist-packages/libvirt.py", line 866, in
create
if ret == -1: raise libvirtError ('virDomainCreate() failed',
dom=self)
libvirtError: Cannot create macvlan devices on this platform:
Function not implemented
Trying to solve the issue, I found this:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737097
I've tried to rebuild the package from Debian sources, but apparently,
macvtap is already defined, as I've reported to another mailing list.

So... yes, it works and builds without any errors.<br>
