( 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): 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.
