This may, or may not, be useful to the sort of work you do, but I also
used it to run a Debian install for a different CPU, in my case an Arm
Debian install running on my x86 PC. I found that getting a PC to
emulate an Arm CPU was a lot quicker and more convenient than doing it
on the Arm single board computers I had. In such a setup, whilst the PC
is having to do lot's of extra works to emulate Arm instructions
for running user code, you are still using the PC's kernel, so disk i/o
is likely an order of magnitude or more faster, and you have available
all the PC's RAM, which is probably a lot more than the ARM board's.

If I remember correct, getting such a setup working was quite straight
forward. To be able to run foreign binaries I think you just need to
install package qemu-user-static and it's recommendation
binfmt-support, and after a quick google just now [1], there is
probably an emulation binary from that which needs copying into the Arm
chroot.
