I'm having this issue with Parallels version 17.1.0 (51516) on Monterey 12.0.1 (21A559) with Apple M1 Max processor and Ubuntu 20.04 aarch64 guest. The workarounds earlier in this thread don't work: using Realtek adaptor - no options in advanced networking to change this. Boot flags, no effect.
Hi please send a problem report (menu help->send technical data) and post here its number. Attach to the problem report the screenshots of how you discovered the issue with MAC or describe it here.
Hi, exactly the same thing happens to me. MacBook Pro (Parallels version 17.1.0 (51516) on Monterey 12.0.1 (21A559)) with Apple M1 Pro processor and Windows 11 guest.
