Public bug reported:
Similarly to LP #341006 other hypervisor MAC address prefixes should be
added to the ignore list.
Currently (Oneiric), /lib/udev/rules.d/75-persistent-net-generator.rules
has:
# ignore KVM virtual interfaces
ENV{MATCHADDR}=="52:54:00:*", GOTO="persistent_net_generator_end"
# ignore VMWare virtual interfaces
ENV{MATCHADDR}=="00:0c:29:*|00:50:56:*", GOTO="persistent_net_generator_end"
# ignore Hyper-V virtual interfaces
ENV{MATCHADDR}=="00:15:5d:*", GOTO="persistent_net_generator_end"
# ignore Eucalyptus virtual interfaces
ENV{MATCHADDR}=="d0:0d:*", GOTO="persistent_net_generator_end"
this list should be expanded to include:
00:16:3e:* (xen, default range used in xen3)
(see, e.g.
http://www.coffer.com/mac_find/?string=00%3A16%3A3E
)
These are not caught by:
# ignore Xen virtual interfaces
SUBSYSTEMS=="xen", GOTO="persistent_net_generator_end"
when on HVM mode without PV drivers, as the device appears as "eth0".
Ideally this would be fixed from Lucid onwards, but should certainly be
fixed for Precise.
