I have no trouble switching to the monitor for a VM with a VNC head: alt-ctrl-2
works as expected in the VNC client.

You can configure qemu to expose the monitor console via any of the serial port
configuration types. That lets you make the monitor available at a udp or tcp port,
e.g.:
# qemu-system-x86_64 <other options> -monitor tcp::4444
The double colon is intended. There are lots of additional features beyond that
example.

That would be the "monitor" command line option then.
