This week Job Snijders advertised<\/a> the latest version of openbsd. I have been always a dreamer of being a hacker (like the movies<\/a>) and the best guys when I was in Uni were Linux users. I had no idea what Linux\/Unix\/BSD was at that time. At the end (by the 4th year in Uni) I managed to install Linux in my windows PC without destroying anything. And fortunately, I have been using it since then. Learning more and still fortunately, in the last 6 years, using it everyday at work too.<\/p>\n\n\n\n

Still very very far away from being a hacker though \ud83d\ude42<\/p>\n\n\n\n

In this time, I have read a bit about the BSD vs Linux threads about licenses, security, etc. And actually I was always keen to learn a bit. In Motorola<\/a>, I had to use Solaris (even managed to get a certification!).<\/p>\n\n\n\n

So this week, I tried to setup a VM in my debian laptop for using OpenBSD 6.7<\/p>\n\n\n\n

I found and followed this link<\/a>, so all credits for the author.<\/p>\n\n\n\n

First I downloaded openbsd 6.7 (install67.iso) from here<\/a>. There are many mirrors around the world. Prepare the file:<\/p>\n\n\n\n

\/var\/lib\/libvirt\/images# ls -ltr\ntotal 1386064\n-rwxr--r-- 1 libvirt-qemu libvirt-qemu 996671488 Apr 6 2018 debian-VAGRANTSLASH-stretch64_vagrant_box_image_9.1.0.img\n-rwxr--r-- 1 libvirt-qemu libvirt-qemu 950796288 Nov 29 23:17 centos-VAGRANTSLASH-7_vagrant_box_image_1905.1.img\n-rw-r--r-- 1 ss ss 470118400 May 21 23:23 install67.iso\nroot@athens:\/var\/lib\/libvirt\/images# chown libvirt-qemu.libvirt-qemu install67.iso\n\/var\/lib\/libvirt\/images# mv install67.iso openbsd67.iso<\/pre>\n\n\n\n
Now start the installation:<\/p>\n\n\n\n
\/var\/lib\/libvirt\/images# virt-install \\\n--name=openbsd \\\n--virt-type=kvm \\\n--memory=2048,maxmemory=4096 \\\n--vcpus=2,maxvcpus=2 \\\n--cpu host \\\n--os-variant=openbsd5.8 \\\n--cdrom=\/var\/lib\/libvirt\/images\/openbsd67.iso \\\n--network=bridge=virbr0,model=virtio \\\n--graphics=vnc \\\n--disk path=\/var\/lib\/libvirt\/images\/openbsd67.qcow2,size=40,bus=virtio,format=qcow2\n\nStarting install\u2026\nAllocating 'openbsd67.qcow2' | 40 GB 00:00:01<\/pre>\n\n\n\n
Something that confused my was that I was installing openbsd6.7 but the os-variant in the command must<\/strong> be obenbsd5.8. Anything else, fails.<\/p>\n\n\n\n
In my setup, I have virt-viewer installed so it opened up and finished the installation using that.<\/p>\n\n\n\n
I was surprised how quick was everything and didnt find any problem:<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Once I logged in, I felt useless \ud83d\ude42 I used a bit the shell and tested I could ssh from my host pc to the openbsd vm.<\/p>\n\n\n\n
So now, I can find a book  of openbsd for dummies and get going!<\/p>\n\n\n\n
So close virt-viewer and stop the VM:<\/p>\n\n\n\n

Test we can start up again:<\/p>\n\n\n\n
