qemu smb share guest<->host

I'm having trouble reaching the qemu smb share from Win10 guest per the instructions https://wiki.archlinux.org/index.php/QEMU#QEMU's_built-in_SMB_server despite enabling WINS for NetBIOS, disabling the firewall, and changing the group policy for guest access. I don't use the same IP address on my guest NIC as in the wiki so my host is reachable differently but I can ping the host at on the virtual NIC or directly to my actual IP of host NIC, so network connectivity is not the issue, but can't reach qemu share to either of them.

The samba log files either at /var/log/samba or /var/qemu-smb.8ABCD0/log.smbd don't exist.

How do I resolve this?

(Also tried alternative virtFS option but maybe it's only for linux guest<->linux host as was unsuccessful.)

EDIT:

QEMU's documentation says it has a "built-in" SMB server, but actually it just starts up Samba on the host with an automatically generated smb.conf file located in /tmp/qemu-smb.random_string and makes it accessible to the guest ...

So I should see a sambad process on the host, but I don't. Is qemu's "in-built" smb server dependent on the installation of a specific version of samba on the host? Maybe samba process on the host can't start through qemu because of a permission issue? I added my $USER to the qemu.conf to ensure that qemu could connect to pulseaudio socket since pulseaudio only accepts socket connections from same user as $USER. Maybe I don't have appropriate permissions to start samba.
