Just to update this thread... I installed 18 on an M1 Ultra the day that it came out and still have the same issues. I cannot resolve networking issues, cut, copy, paste into the VM. Drag files into the VM, auto mount a local folder to get files into the VM or set any other configuration for Disk Size, CPU count or Memory. Since this is for work I can connect 1 File Server but not others and somebody was kind enough to give me a folder for file transfers. Which take forever. 45 minutes to transfer out and back. This should be close to immediate since the files are local. In short the Mac VM while snappy locally is next to useless since I can't work reasonably with it. Is there any ETA on this being fixed? Oh if this was for home I wouldn't have a work around. No file servers @ home.
