[Hyper-V] hv_set_ifconfig fails due to new netplan configuration

[bogdan carpusor]

Issue description: hv_set_ifconfig does not work due to new netplan configuration

Platform: host independent
Distribution name and release: Ubuntu 18.04
Kernel version: 4.15+

The hv_set_ifconfig script does not take in consideration netplan config files. Consequently, the changes made by hv_set_ifconfig in /etc/network/interfaces are not affecting the final network configuration.

Status changed to 'Confirmed' because the bug affects multiple users.

Joseph Salisbury, can you please mark this for Bionic as well?
I see this remained for generic Ubuntu, but it affects all releases that use netplan.

[Joseph Salisbury (jsalisbury)]

Do we know if this is a regression?

Also, would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.20 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Is there any update on this? I am on Kernel 5.13.0-1022-azure and linux-cloud-tools-common 5.4.0-109.123 and the script hv_set_ifconfig is only able to manipulate /etc/network/interfaces.

Kind Regards

Hi!,

I was able to fix this by adding the ability to create the netplan yaml files from the hyperv-input.
In my case everything works fine. I tested it with 18.04 LTS and 20.04 LTS. It adds .bak the default 01-netcfg.yaml and any previous files for the same interface you want to edit. It creates a seperate yaml-File for each interface when you edit it via the hyperv-host or via scvmm.
