Mount qcow2 to Ubuntu host:

Temporally create qemu-nbd mount points by:

sudo modprobe nbd

sudo qemu-nbd  -c /dev/nbd0 -f qcow2 *.qcow2
sudo qemu-nbd -d /dev/nbd0
*Also eject the partition to fully remove.

To unmount nbd driver from system:
Option 1: Run #sudo modprobe -r nbd
Option 2: Reboot host to clear all /dev/nbdX drives.

Update (July 23rd, 2024): (Figured out how to un-mount nbd driver).

Update (May 16th 2025):
I just realized you can mount vmdk files with qemu too, instead of relying on VMware's unstable mounting option by:
sudo qemu-nbd -c /dev/nbd0 -f vmdk *.vmdk
