How can I get Hyper V to detect my Ubuntu VM's IP Address

Question

I just installed a new ISO downloaded from Ubuntu.com today, just installed it to a new machine. Networking is working just fine, but the IP address isn't getting picked up by the Hyper-V manager. I am trying to make a base box for vagrant, so I need networking to actually report the IP address.

Console output for ping, ifconfig, and lsmod:

Answer 1

Ok, I figured this one out.

The tl;dr version:

sudo apt-get install "linux-cloud-tools-$(uname -r)"

Normally you'd install linux-cloud-tools-virtual to get the KVP daemon installed. Unfortunately, the kernel version that ships with Ubuntu 14.04.3 is 3.19.0-25-generic, whereas linux-cloud-tools-virtual installs the cloud tools for 3.13.0-65-generic. So obviously you need to install the cloud tools for your kernel's release version. To do that automatically you need to get your relase version using uname -r, as above.

Hope that helps somebody somewhere along the line.

Answer 2

seems like for 18.10 the sudo apt install linux-cloud-tools-virtual is what is needed again

Answer 3

For my Ubuntu 20.04, I followed this guide for Ubuntu 18.04. I can see from the lsmodoutput from the question, that he doesn't require the first steps, but I wanted to post a more complete guide.

First edit the modules file (using nano) to add additional modules:

    sudo nano /etc/initramfs-tools/modules

and add following lines:

    hv_vmbus
    hv_storvsc
    hv_blkvsc
    hv_netvsc

Now install the virtual tools, update the initramfs modules and reboot:

    sudo apt-get install linux-virtual linux-cloud-tools-virtual linux-tools-virtual
    sudo update-initramfs -u
    sudo reboot
