[Bug 1301019] Re: hyper-v: ifdown command not working due to bad ifstate

 

@apw the python script is assuming that the NIC is configured via
/etc/network/interfaces. Over a year ago we changed Cloud Images from
using /etc/network/interfaces with the primary configuration to using
/etc/network/interfaces.d/<INT>.cfg and using /etc/network/interface to
source them. Bare metal installations

I have confirmed that our version of hv_set_ifconfig does not handle
this change. Bare metal installations from media should be using
/etc/network/interfaces, so the installed script should continue to work
just fine.

Title:
  hyper-v: ifdown command not working due to bad ifstate

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  It appears that ifdown command is not working because
  “/run/network/ifstate" does not contain eth0=eth0.

  This in turn causes hyper-v's script hv_set_ifconfig.sh to fail as
  follows:

  root@ubuntu:~# ./hv_set_ifconfig.sh /var/lib/hyperv/ifcfg-eth0
  ifdown: interface eth0 not configured
  RTNETLINK answers: File exists
  Failed to bring up eth0.

  It appears that something is wrong with your core networking files for trusty. Please could you help fix?
  Thanks,
  Abhishek
