I have my Ubuntu 18.10 host and a Windows 7 guest on VMware Workstation Pro 15.0.3.
I was in the guest and some how I froze it, then the guest freezes VMware and I got trapped: I wasn't able to get out of the VM because VMware was capturing all of my inputs (EVEN MY POWER BUTTON!!!) and it was freezing, and because of that I couldn't click or type, or hot keys, tty keys or ANYTHING. Although the host wasn't freeze but my input was bricked then it was like my host is bricked. I had to hard reset and lost all of my work, even though I was able to save them.
VMware freezes on my host, most of the time when my VM freezes of when executing tasks.
I don't know why but VMware is having so many probelm on my Linux host. I can't update VMware tools, VMware system is buggy and traps me many times. I never have this kind of problems on Windows and... I really don't want to say this but switching VMware from Windows to Linux is like WTF.
