failed to raise network interfaces

[rilakk...@gmail.com]

hi all
i tried the virtual machine version 4.7-ubuntu 16, but encountered "failed to raise network interfaces" during boot, it cannot automatically get an ip address by itself
i can only get an ip address by manually typing "dhclient ens3"

===

virtual machine version 4.6-ubuntu 14 has no such problem

===

i am using virtualisation station v2.2 on a qnap nas tvs-463 firmware v4.2

something different between ubuntu 16 vs 14?
any ideas?

Hello Rilakkuma,

We have no reports of such behavior but we only test on VMware vSphere.
May be this helps - https://docs.diladele.com/administrator_guide_4_7/virtual_appliance/addresses.html

Best regards,
Rafael

so i followed the link and setup static ip and it works
i also search around and came across this
http://www.itzgeek.com/how-tos/mini-howtos/change-default-network-name-ens33-to-old-eth0-on-ubuntu-16-04.html
this also works
but now if I have an ip address, reboot/shutdown just hangs, so I guess ubuntu 16 maybe not compatible with virtualisation station, or there is a bug somewhere
I'll try to dig deeper and figure it out, otherwise I'll just stick to v4.6 with ubuntu 14

Im having the same issue with 4.8.0.935B on VirtualBox...no damn network

Setting static hasnt worked so far....grrrrr

Tried the trick here: http://www.itzgeek.com/how-tos/mini-howtos/change-default-network-name-ens33-to-old-eth0-on-ubuntu-16-04.html

Ip address changed to static, but still cant connect to it....grrrrrr

Finally got the eth0 to stick, but still needed to use dhclient eth0 to get a valid ip, and connected...finally

This happens to me as I convert the VMware image to Hyper-V.  

I always have to do a "lshw -class network", view the Linux denomination for virtual network adapter (usually eth0 in HyperV). 

 Then "sudo nano /etc/network/interfaces"

Change the Vmware interface "encs160" or similar to "eth0" - press CTRL + X, press Y and ENTER.  You can then either reboot or issue the command "ifup eth0"
