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:

According to this social.technet.microsoft.com/Forums/en-US/… it seems to have something to do with the kvp daemon in linux-cloud-tools-virtual. – Featherweight

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.

This worked perfectly for me in 16.04, but not in 17.10 – Asseverate

This worked for me in Ubuntu 18.04.1 LTS guest on Windows 10 Enterprise Host. Without the "quotes". sudo apt-get install linux-cloud-tools-$(uname -r) – Champlain

It worked for me, Deepin linux.Finally I can ssh into my vm without connect in and ifconfig to check the ip.Thanks! – Twibill

If you install the package for your exact kernel version, is there a risk of it going stale when the kernel is updated, or will apt keep them both up to date going forwards? – Transfer

Answer 2

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

Lakeshialakey

this package name is valid as of 20.04 – Kenzi

This worked for me in 22.04 after a reboot. – Transfer

Answer 3

Ubuntu 20.04

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

Ubuntu 24.04

As suggested by other people's comments, for my most recent installation of an Ubuntu 24.04, executing the apt-get install and the sudo reboot commands was sufficient

Threedimensional

In 20.04, it was enough for me to do the apt install and reboot. – Transfer

Answer 4

On Ubuntu 22.04 Server, (similar to @mwfearnley)'s comment on https://mcmap.net/q/651114/-how-can-i-get-hyper-v-to-detect-my-ubuntu-vm-39-s-ip-address, I only had to:

sudo apt install -y \
  linux-virtual \
  linux-cloud-tools-virtual \
  linux-tools-virtual

sudo reboot now

This did NOT work for me in Ubuntu Studio 22.04 LTS. I've tried literally everything, and can't get the IP address of the guest VM to show in the Hyper-V manager, or via Get-VMNetworkAdapter in PowerShell. I'm ripping my hair out at this point. – Utterance

Answer 5

On Ubuntu 22.04 if you installed the kernel from HWE then you need to install

linux-cloud-tools-virtual-hwe-22.04

After you reboot it should work. At least this is what I have done.
