Here is the vmware.log. Mind you that this is a failed attempt to start Windows 7 VM. It took minutes to get into the "background page of Windows start" and then, after another several minutes, there was still no login page for Windows 7.

As stated before, all the other VMs, Win10 and Win7, fresh or old, give a similar issue on Ubuntu 20.04.1 Host. Windows 10 Host works fine in all cases.

Message to add more swap to Linux, I have ignored. RAM is 16 GB and should be enough for everything. Perhaps there is some memory allocation problem in VMware, but I don't know how to solve that. VM is NOT allocated to take too much or too little memory (perhaps under 10 GB currently).

If this is a memory allocation problem, I need advice. I have used VMware Workstation Pro (or Player) for 15+ years on Windows and Ubuntu, and used easily over 100-200 DIFFERENT VMware computers and never had something like this. So this is new to me. I was even able to run a 3D CAD-application with SQL Server on VM on a 1 GB Asus/Linux minicomputer in VMware - it is the only one that was equally slow, but it did work. This, I'm not sure if it even works.

EDIT: In case you are wondering, I did rename username and diskname in the vmware.log.
