Re: [libvirt-users] Cannot create macvlan devices on this platform

Hi,
libvirt (0.9.11) refuses to start KVM based virtual machines on my
system when changing the network connection from "host bridge" to
"direct" (macvtap/macvlan), neither in "bridge" nor in
"vepa" mode:
"Cannot create macvlan devices on this platform"
That's astonishing because I can easily setup working macvlan devices
using the "ip" command: "ip link add link eth0 type macvlan".
Would someone help me figure out the reason?
This error message occurs if macvtap support was missing when libvirt
was compiled. Based on the configure.ac check, whoever compiled your
libvirt package did not have new enough kernel headers to have the
following constants present
MACVLAN_MODE_BRIDGE
IFLA_VF_MAX
which should be in linux/rtnetlink.h
