no Internet connectivity on Parallels 19 running macOS 14

[MHWill]

Hello. I recently upgraded from Parallels Desktop 18 to v19, running on a Mac Studio with an Apple M1 Max chip. While still on v18, I had previously installed Windows 11 and macOS 13 Ventura. Once on v19, I installed a new instance of macOS 14 Sonoma (not upgrading/overwriting over macOS 13).

My macOS 14 VM has no ethernet internet connectivity (DHCP with an IP of 169.254.143.151).

However my macOS 13 VM connects just fine (DHCP with an IP of 192.168.64.26).

I have tried manually configuring macOS 14 using the same router, subnet and DNS addresses that work on macOS 13, but to no avail. (I can connect to my host Mac, naturally.)

Any ideas?

Hello,
Kindly try performing the steps below as a workaround for the issue with the lack of network access inside a macOS Sonoma VM and share with me if it works for you:
1. Open Terminal.
2. Execute the command below (once done, it'll ask you for the Ma administrator password; please enter it and hit Enter to execute the command):
sudo nano /Library/Preferences/Parallels/network.desktop.xml
3. Locate the following string:
<SystemFlags></SystemFlags>
and paste the devices.net.use_naptd_for_macvm=0 value to make it look like this:
<SystemFlags>devices.net.use_naptd_for_macvm=0</SystemFlags>
Note: use arrow buttons on your keyboard to navigate.
4. Press Control and O buttons on the keyboard to save the changes and then hit Enter.
5. Press Command and Q shortcut to quit the Terminal.
Check if the issue remains. If it does, kindly reproduce the issue, and collect a technical report (right-click Parallels icon in Dock > Help > Send technical data > check "Attach screenshots..." > press Send Report) and provide us with the report's 9-digit ID in reply to this post.

This worked for me after following the steps and restarting my mac.
Thanks!
