Most guests generate this on first boot. I haven't looked into how newer versions of ubuntu handle this though I noticed in 14.04 this file doesn't exist anymore but I figure it's doing it somewhere else. Aaron On Wed, Aug 13, 2014 at 9:03 PM, Jian Wen wenjia...@gmail.com wrote: Ordering of

Ordering of vNICs is not 100% guaranteed for the cloud images which are not shipped with /etc/udev/rules.d/70-persistent-net.rules. e.g. attaching a port and deattaching another port, then reboot the instance. 2014-08-12 15:52 GMT+08:00 Aaron Rosen aaronoro...@gmail.com: This bug was true in

2014-08-08 Thread CARVER, PAUL
I'm hearing friend of a friend that people have looked at the code and determined that the order of networks on a VM is not guaranteed. Can anyone confirm whether this is true? If it is true, is there any reason why this is not considered a bug? I've never seen it happen myself. To elaborate,
