Installation

OpenBSD can be downloaded from the official page. After installation you should manually configure package repository. Read more about package management on OpenBSD. GCC and Clang are both distributed through the packages.

OpenBSD does not support multilib configuration so you cannot build and run x86 binaries on x64 machine.

qemu-system-x86_64 -m 2048 -M pc -smp cpus=2,sockets=1,cores=2,threads=1 \
  -drive media=cdrom,if=none \
  -drive file=openbsd.qcow2 \
  -nic user,model=rtl8139,hostfwd=tcp::10022-:22
