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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1338185 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.
