    The fix from Khorém works (thanks!), but it has a very annoying side-effect for me: the VM does not use the MAC address it is supposed to use, but an arbitrary one. Since our environment only grants network access to registererd MAC addresses this is pretty bad. I now have to find out which MAC address is used and register it.

    Just landed here from Google with the same problem. I used the text version of Parallels for M1 and now have updated to the latest version. I had fully working Ubuntu and Windows 10 running. After the update of Parallels to the latest version Ubuntu has no network. Above fixes of changes to a 1 or 0 did not fix it. Windows VM works fine.

    I tried everything above to no avail. Got it working by additional steps. Listing all I did, maybe step 1 is not necessary.
    Big Sur 11.3.1, Parallels 16.1.2 on a custom hackintosh build.

    1. open mac System preferences - network. Select Parallels shared and press minus button to remove it. After it asks whether to reinstate network when it appears again, press yes. Then click APPLY. You must not forget to click apply.

    2. open Terminal, sudo su [enter], type password, [enter]. You are now root.

    3. list all running parallels services
    bash-5.1# ps -ef|grep [P]arall
    501 129 1 0 3:12PM ?? 0:00.95 /Applications/Parallels --start-services
    0 568 129 0 3:14PM ?? 0:00.01 /Applications/Parallels Service start
    0 570 568 0 3:14PM ?? 0:00.01 /bin/bash -s -- start /Applications/Parallels
    0 578 570 0 3:14PM ?? 0:09.04 /Applications/Parallels --pidfile /var/run/ --launchd-mode
    0 595 570 0 3:14PM ?? 0:00.54 /bin/bash /Applications/Parallels start 60 20 /Applications/Parallels start
    0 618 595 0 3:14PM ?? 0:00.43 /Applications/Parallels start

    As you see, there are still many running despite parallels is closed.

    4. Kill parallels services. Use PIDs from the second column, and use them in reversed order (last to first).
    kill -9 618 595 578 570 568 129
    Now parallels is dead dead, murdered, nuked. We can edit the file.

    5. Edit the /Library/Preferences/Parallels/network.desktop.xml
    Add <UseKextless>0</UseKextless> anywhere between lines <ParallelsNetworkConfig schemaVersion="1.0" dyn_lists="VirtualNetworks 1"> and <VirtualNetworks id="0" dyn_lists="VirtualNetwork 6">

    6. Start parallels services
    /Applications/Parallels\ --start-services &
    (press 2x enter after this command)

    7. Start parallels app and the VM.
