A reversible VM isn't *quite* the same thing. (There was a reversible VM project for Linux based on UML, called ReVirt, but it was an academic project so it suffered the usual fate of such and died as soon as the funding went away. I keep wishing someone would bring one back again, but, admittedly, without ever actually doing anything toward that end myself.)

No, but VMware supports reverse *debugging*, with gdb.
You run gdb on the host, and debug the guest (either user process or kernel). When you say "reverse-continue" in gdb, VMware executes the guest backward until it hits a breakpoint or watchpoint.

i.e., a reversible VM (with the reversibility interface being GDB,
definitely a good decision.)
