( Posting again. Correct subject line now! )
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):

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.
For your information:
I'm new to building packages from Debian
sources, so I followed instructions from
https://wiki.debian.org/HowToPackageForDebian#Building_Debian_packages
$ apt-get -t wheezy-backports source libvirt
$ cd libvirt-0.9.12.3/
$ sudo apt-get build-dep libvirt
$ debuild -i -us -uc -b
So... yes, it works and builds without any errors.
Next step now is applying the changes mentioned.
But I'm confused because apparently debian/rules is
already the way it should be.

WITH_NETWORK = --without-network
WITH_QEMU = --without-qemu
WITH_LXC = --without-lxc
WITH_NUMA = --without-numactl
WITH_NETCF = --without-netcf
endif
I suppose that nothing has to be changed, correct? ... since the then
branch already has the change mentioned and the else
branch probably means that nothing related to networking would be
enabled anyway.
Am I missing something ?
Thoughts?
Thanks a lot :)
