NIC interface names

[Boris Epstein]

Hello listmates,

I recently installed Fedora 16 as a guest VM under VirtualBox and instead
of the usual eth0/eth1 etc. names I got the following:

[root at ipa-test0 ~]# ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host

          RX packets:12 errors:0 dropped:0 overruns:0 frame:0
          TX packets:12 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:812 (812.0 b)  TX bytes:812 (812.0 b)

p2p1      Link encap:Ethernet  HWaddr 08:00:27:1C:C1:37
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

p7p1      Link encap:Ethernet  HWaddr 08:00:27:D2:29:56
          inet6 addr: fe80::a00:27ff:fed2:2956/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:43 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:13122 (12.8 KiB)

[root at ipa-test0 ~]#

Any idea where these strange names come from and what the significance of
them is?

Thanks.

Boris.
