2019/08/09: VMware has pushed out an update that mitigates the issue when your VM is encrypted. More details by VMware employee ksc (at the bottom). Note that this does not yet fix all issues!
2019/08/02: There’s an update from VMware .. see at the end of the post.
The latest update from apple for macOS 10.14 (and macOS 10.15) changed something in such a way that Virtual Machines running under VMware Fusion 11 now suffer serious performance problems. So much so that using those VMs becomes very hard to impossible.
This thread describes the problems you bump into if you try to upgrade a macOS Mojave VM to the new beta macOS Catalina. Basically if you run the upgrade then your VM will hang on reboot. If you then try to reboot it in verbose mode, so that you can see what happens, you’ll get the following screen.
Now that the dust is slightly starting to settle It became clear to me that there’s an enormous amount of information and confusion out there. I have read a lot of websites in order to get a clear picture and being able to get all of my hosts and Virtual Machines patched. While not completely done yet, here’s my collection of links and some answers on questions that I see asked often. This is a live document and will be updated with notes relevant for patching.

With the new Workstation 14 and Fusion 10 there is also a new requirement for your CPU’s. This unfortunately has not been clearly communicated about by VMware. When you try to start a VM and get the error:
This host does not support virtualizing real mode. The intel “VMX unrestricted Guest” feature is necessary to run this virtual machine on an Intel processor.
Module ‘CPUIDEarly’ power on failed
Failed to start the virtual machine
You’re one of those lucky ones with a CPU that is too old.
As of VMware Workstation 12.0 unity support for Linux has been removed. Whereas unity support for Windows 10 is one of the few areas where there is actually additional support for Windows 10, that same feature has been ripped out for Linux hosts and guests.
As you might or might not know, you can change your VMs nowadays to boot via EFI instead of the Plain Old BIOS.
This is great as you can now experiment with EFI without messing up your physical environment or having to reboot on metal.
There’s ongoing work on VMware Fusion and Workstation to improve UEFI support. In VMware Workstation 10, this was unsupported, but it worked.
Workstation 11 now has a option for this under VM Settings -> Options -> Advanced -> Boot with EFI instead of BIOS. With Fusion 7 you either have to edit the config file by hand or change it to another guest OS that uses EFI.
For quite a while now (years) there had been reports of users having problems with the Shared Folders feature in VMware Fusion and a newer version of Windows (Windows Vista / Windows 7 / Windows 8). After clicking around on a shared folder in the tree of Windows Explorer the CPU would go to 100% and lock your VM up for a minute or more.
