TLDR

vmctl create -s 50G disk.qcow2
vmctl start -m 1G -i 1 -b /bsd -d disk.qcow2 myvm
vmctl show #will show mywm
vmctl console myvm
vmctl stop myvm

WORKING OS

back_to_top

OpenBSD, centos, archlinux, opensuse.

SERIAL CONSOLE

back_to_top

Some linux distributions may not have the serial console enabled by default, the following is an example for Slackware lilo.

On the boot loader press tab.
type:
huge.s serial 0 115200, console=ttyS0,115200
to disconnect from the console but keep the vm running: [ENTER] ~^d

: This has been tested on slackware, centos, archlinux, opensuse.

INTERNET ACCESS

back_to_top

host

allow forwarding.
sysctl net.inet.ip.forwarding=1
vm.conf:
```
vm "vm_name" {
	...
	local interface
}
```

pf.conf : this provides the vm with a dns.

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 192.168.1.1 port domain

reload pf.conf: after this the vm will have internet access.
pfctl -f /etc/pf.conf

PORT FORWARDING

back_to_top

The vm can be accessed through ssh from the host using the local interface:

ssh 100.64.1.3

For external access, follow these steps:

allow external access (pc other than the host) using pf.
pass in on egress proto tcp from any to any port [EXTERNAL_PORT] rdr-to [VM_IP] port [VM_PORT]
reload pf.conf: after this the vm will be accessible by other machines in the network.
pfctl -f /etc/pf.conf

example

example	: ssh
host ip	: 192.168.1.10
guest	: 100.64.1.3

pf.conf (on the host):
pass in on egress proto tcp from any to any port 10122 rdr-to 100.64.1.3 port 22
Reload pf.conf:
pfctl -f /etc/pf.conf
ssh command:
ssh -p 10122 192.168.1.10

TODO

back_to_top

test and document real host in the network.
slackware: unable to load virtio, it doesn't detect vda. This was an issue at some point, needs to be re-tested.
Verify parameters for other linux distributions.
Add permanent kernel parameters.
