Good afternoon MG (heyrastamon),

Thanks for the feedback here.  I can confirm that I performed my upgrade
to 14.04 in a Hyper-V VM with 4 GB of RAM assigned.  When I tried the
new installation, I also chose 4 GB for the new VM so got the same
networking failure.

I saw the note that the 32-bit download is "for machines running 2GB or
less", but as you experienced with 12.04LTS I was also able to use a 4GB
VM for some recent versions of 32-bit Ubuntu.  Since the memory >2GB was
recognized in recent Ubuntu versions, I assumed PAE was in use and that
the 2GB constraint listed with the download was deprecated.

I'll go back down to 2 GB temporarily and see if it works, but it
definitely seems like there's a legit bug in here somewhere.

Title:
  networking fails in 32-bit 14.04 using HyperV on Win2012R2

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I was running Ubuntu 13.10 32-bit as a VM on a Windows Server 2012 R2
  machine with Hyper-V.  In 32-bit 13.10, networking worked properly at
  all times, from the first installation to normal usage.

  I ran the upgrade to 32-bit Ubuntu 14.04 and discovered that
  networking is no longer working.

  To eliminate the possibility that there was a botched upgrade, I tried
  a fresh install in another VM.

  I performed a fresh install of 32-bit Ubuntu 14.04 in Hyper-V from
  ubuntu-14.04-desktop-i386.iso, and I noticed that the network was not
  connecting during the first part of the installation before any files
  are copied to the disk.  After the installation completed, there was
  no eth0 device present.

  By comparison, I performed a fresh install of 64-bit Ubuntu 14.04 in
  Hyper-V from the ubuntu-14.04-desktop-amd64.iso, and networking worked
  properly at all times from the start of installation.

  To summarize, networking is failing in 32-bit Ubuntu 14.04 under
  Hyper-V in Windows Server 2012 R2.  Networking is working properly in
  32-bit Ubuntu 13.10 on the same machine.  Networking is working
  properly in 64-bit Ubuntu 14.04 on the same machine.

  Any suggestions on getting 32-bit Ubuntu 14.04 to work in my Hyper-V
  VM ?

  Thanks.
