How to run Wine on OpenBSD

Note: this is incomplete To run Wine on OpenBSD you need to emulate it within a VM. But it's not that bad since OpenBSD comes with a kernel level hypervisor called VMM that's quite good.

• Add the following to /etc/sysctl.conf: net.inet.ip.forwarding=1 then run sysctl -f /etc/sysctl.conf to apply the changes
• Next, append the following to /etc/pf.conf, (change dns-server)!

• dns-server = "1.1.1.1"
  match out on egress from 100.64.0.0/10 to any nat-to (egress)
  pass in proto { udp tcp } from 100.64.0.0/10 to any port domain \
    rdr-to $dns-server port domain
    

Reload pf with pfctl -f /etc/pf.conf

Virtualization on your CPU must be enabled. VMD will not work otherwise. Linux is supported, Alpine Linux is known to work best, but I think you can use anything.

• rcctl enable vmd
• rcctl start vmd
• Now create a disk: vmctl create -s 50G disk.qcow2 (Note: 50G is only the upper limit of the virtual disk's size, not its actual size)
• vmctl start -m 2G -L -i 1 -c -r <PATH TO ISO> -d disk.qcow2 <VM NAME>
• After installation finishes, vmctl stop <VM NAME>
• (Optional) Add a line to /etc/hosts with your VM's ip:

• 100.64.1.3      alpine.local
