Setting a private IP address does not work

[remilapeyre]

Configuring static IP addresses for the private_network using the configuration given at https://parallels.github.io/vagrant-parallels/docs/networking/private_network.html does not work.

Vagrant version:

$ vagrant version
Installed Version: 2.4.0
Latest Version: 2.4.0

You're running an up-to-date version of Vagrant!

Vagrant parallels plugin version:

$ vagrant plugin list

Parallels Desktop version:

$ prlctl --version
prlctl version 19.1.1 (54734)

end

Running vagrant up:

But the IP address is wrong:

$ vagrant ssh -- ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

The IP address 10.37.132.10 differs from 10.37.130.6. I think the private network is still using DHCP.

Running into the same issue, it sets the private IP address on a new interface eth1 leaving eth0.

For any passers-by:

As of Vagrant 2.4.3, this is still an issue but it's specific to Fedora 36 and newer boxes. Upstream issue hashicorp/vagrant#12762 covers the issue in detail, but TL;DR Fedora no longer supports how Vagrant tries to configure static interface via ifcfg-rh files, instead it should be using NetworkManager keyfiles. Appropriate workaround pending a fix in the upstream would be to manually configure the additional interface it creates with the desired address with nmcli.

You probably don't want to fiddle with the eth0 interface since that's attached to the shared network and is what Vagrant/Parallels is using to provide SSH access and general WAN access.
