As for as I know, "running multiple instances of QEMU at the same time" is
feasible for user-mode emulation, namely emulting CPU, according to
https://en.wikipedia.org/wiki/QEMU.
Wikipedia says
"Virtualization solutions that use QEMU are able to execute multiple
virtual CPUs in parallel. QEMU is also able to run multiple threads in
user-mode emulation mode.
For full system emulation, QEMU uses a single thread to emulate all the
virtual CPUs and hardware. "
However, what I need is system emulation, an ARM processor with various
periphrals.
I think Peter is right.
