The process has been documented on wiki.

I recommend to upgrade to 8.0.

One extra step is to disable PaX MPROTECT (tcg violates W^X):

This should be addressed in qemu with an extension flag to
mmap(2)/mremap(2). I still have this on my TODO list.

sysctl -w security.pax.mprotect.enabled=1

NetBSD 9.0 will be released sooner than later and soon after that
NetBSD-7.x will be EOL.
