Mount a Windows host's folder on a QEMU Linux guest

qemu_vm_mount_windows_local_folder.sh

#! /bin/bash

# The Windows folder needs to be shared appropriately
WINDOWS_DIR_PATH="//10.0.2.2/workdir"
MNTPOINT="/workdir_local"

if [ ! -d "$MNTPOINT" ]; then
  mkdir $MNTPOINT
fi

if [ -z "$WIN_USERNAME" ]; then
  echo "Please set WIN_USERNAME in .bashrc"
  exit 1
fi

umount $MNTPOINT > /dev/null 2>&1
echo "Use your Windows password to mount $WINDOWS_DIR_PATH at $MNTPOINT"
mount -t cifs -o user="$WIN_USERNAME",uid=501,gid=501 "$WINDOWS_DIR_PATH" "$MNTPOINT"

Here is my solution to mount a Windows host shared folder on Ubuntu guest

On Windows host, a shared folder need to be setup, right click a folder, Properties -> Sharing, e.g shared_windows_folder

On Ubuntu guest, do the following

sudo apt install cifs-utils
sudo mount.cifs -o user=$WINDOWS_USER,uid=1000,gid=1000 //10.0.2.2/shared_windows_folder /mnt

You will see shared_windows_folder content on /mnt.
