Works in QEMU with couple hiccups. Emulation speed is slow though.

I can vouch for armel, armhf, mips64el, ppc64el and arm64. And amd64,
but I don't use it that much.
These architectures work to a point of installing and using your typical
server software, and can be used for other OSes too. That's assuming
your typical x86-64 host.

Less popular arches (such as sparc64 or s390x) are more or less
broken. But that's QEMU, they break and fix things all the time.

Usually works as advertised, but setting things up can be hard. QEMU has
either bad or obsolete documentation, depending on who you ask.

Definitely a real package. It's of limited use for me as QXL is for
x86(-64) guests only.

An obsolete package. You need qemu-system metapackage.
