vm: Implement the VM interface for VMware Workstation

[rgerganov]

Use the "vmrun" utility to manage Workstation VMs. The syzkaller manager
creates temporary VMs (linked clones) from a base image, gets their IP
address and uses ssh to deploy and run programs (similar to the isolated
mode).

Nice!
I guess this can find some bugs in vmware as well. I would flip all possible device emulation, virtio transports, etc flags on and build vmware with ASAN/MSAN.

Yup, that's the exact same bug that I found when fuzzing locally. Syzbot is doing a great job!
How can I link the pending patch https://lore.kernel.org/lkml/20200825164522.412392-1-alex.dewar90@gmail.com/ with this syzbot report?

[dvyukov]

You need to reply to the syzbot report email with "#syz fix:" command:
https://github.com/google/syzkaller/blob/master/docs/syzbot.md#communication-with-syzbot

Have you received the report email? If not, I can do it.
Also possible to just send a email to the Reported-by address: syzbot+f58fe4bb535845237057@syzkaller.appspotmail.com

[rgerganov]

Done. Thanks!
