Re: [Devil-linux-develop] Assign network interface names.

[Serge L. <ser...@gm...>]

Hi,


OK, the brief update.  "--enable-rule_generator" works (adds persistent-net and 
  persistent-cd).

During the testing (in KVM) I found the following lines in 
persistent_net_generator which floored me:

# 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"

I have no idea why persistent_net should not work in virtualized environments. 
For me it looks like a bug/mistake.
I'd be happy if you share your opinion.

Serge
