[Bug 1540586] Re: Hyper-V] Netmask value is not parsed by hv_set_ifconfig - IP injection

 

Parsed ifcg-eth0 file that is going to be converted to a network
interface config on the guest

** Description changed:

  This bug is a continuation to bug ID 1506521 - the refreshed
  hv_set_ifconfig script in Python3.
  
  On a Wily system with the new script, doing an IP injection does change the IP on the VM, however the netmask value is not parsed and gets ignored.
  It gets set to a default of 255.0.0.0.
  
  Kernel: 4.2.0-23-generic
  
  Generated ifcfg-eth0 file:
  /var/lib/hyperv/ifcfg-eth0
  
  Sample contents:
  HWADDR=00:15:5D:XX:XX:XX
  DEVICE=eth0
  BOOTPROTO=none
  IPADDR0=10.123.120.12
  NETMASK0=255.255.254.0
  GATEWAY=10.123.119.1
  DNS1=anything
+ 
+ syslog doesn't record any related events to the netmask, and also
+ manually executing hv_set_ifconfig against the generated ifcfg works
+ with no errors.
+ 
+ The interfaces files gets modified to this:
+ iface eth0 inet static
+         address 10.123.120.199
+         gateway 10.123.119.1
+         dns-nameservers anything_changed
+ 
+ #End of hv_set_ifconfig stanzas
