I'm sure someone has figured this out--how can I make zsh shell default for a given VM? The chsh tool requires I set a user password, then neither the password or shell change persist.

First of all, I have never used chsh. And havent tested this.
They dont persist because the files chsh tries to modify [1] are not persisted / readonly to the VM. If you are using a template based VM, the chsh command should be launched in the template, *but* it would change the shell to all VM's based in that template. To avoid that there are different options:
a) Using templates: Copy the default template into a new one, modify (chsh) the new template. Use the custom template in your VM
b) Use a standalone VM
IMHO it is good practice not messing with default templates, network VM, firewall VM could be affected otherwise. If you decide going tweaking default template, consider creating a backup first ;-)

I changed it in my template w/ chsh. Can't have too much zsh. Plus, if a file is needed to be run with #!/bin/bash it will be, so I don't expect any breakage. THANKS POSIX!!

That is indeed true in your use case, but I mentioned in case future modifications/customizations could break the system. I like leaving default template as-is and copying it before adding repositores (utrusted or untrusted), editing files, etc.
Example:
default template: As-is. netVM, firewallVM
LAN template: Added repositories, /etc/fstab edited to add entry to local network NAS (user data + backups, samba shares with different users)
- backup VM. Uses LAN template. Specific user 'backup' used in fstab mount via /rw file.
- nas VM: Uses LAN template. Specific user 'nas' used in fstab mount via /rw file.

want changes on just one AppVM, you could put a sed script in
/rw/config/rc.local to do the replacement at each boot.
Alternatively, you could have a fixed version of your /etc/passwd in
/rw and copy that over using the same mechanism.

Or, presumably, you could include the appropriate 'chsh' command in
rc.local to achieve the same thing. (Not tried this, but I'm
considering this approach for something similar.)

Yeah, chsh would be a much better solution. I didn't even know that

was a thing, I've always just edited /etc/passwd directly. Thanks for
