Dlock.bitraf.no
dlock.bitraf.no er en virtuell server som brukes av låsstyringssystemet til Bitraf. Maskinen kjører dlock[1] programvare, i rolle som dlock gateway. Konfigurasjonen av maskinen er gjort ved hjelp av ansible[2]. En dlock gateway kommuniserer med låsstyringer koblet til systemet, og sender melding om at dører / låser skal åpnes når den mottar melding om det. I Bitrafs tilfelle kommer slike meldinger fra p2k16.

- unfortunately, I had connected the machine to the wrong bridge when I configured it
tingo@bite:~$ virsh --connect qemu:///system domiflist dlock Interface Type Source Model MAC ----------------------------------------------------------- vnet15 bridge br0 virtio 52:54:00:02:0d:99
fix that by editing the vm
virsh --connect qemu:///system edit dlock
and change br0 to br1, the nrestart the vm and check
tingo@bite:~$ virsh --connect qemu:///system domiflist dlock Interface Type Source Model MAC ----------------------------------------------------------- vnet15 bridge br1 virtio 52:54:00:02:0d:99

- install the virtual machine, start the installation
tingo@bite:~$ sudo virt-install --connect qemu:///system --name dlock --memory 4096 --vcpus 2 --hvm --location /var/lib/iso/debian-10.10.0-amd64-netinst.iso --disk /var/lib/libvirt/images/dlock.qcow,size=20,format=qcow2,bus=virtio --network bridge=br0,model=virtio --os-type=linux --os-variant=debian10 Starting install...

You can reconnect to the console to complete the installation process.
then from another session (started with `ssh -Y machine`start virt-viewer
tingo@bite:~$ virt-viewer --connect qemu:///system dlock (virt-viewer:28257): GSpice-WARNING **: 14:59:30.196: PulseAudio context failed Connection refused (virt-viewer:28257): GSpice-WARNING **: 14:59:30.196: pa_context_connect() failed: Connection refused
then you get a windows on your machine, which runs the Debian installer, and you answer the normal way. Tingo (diskusjon) 19. aug. 2021 kl. 22:43 (CEST)
Choices made in the installer: unselected Debian desktop environment, print server, selected SSH server, "standard system utilities" was selected, I didn't change it. Tingo (diskusjon) 19. aug. 2021 kl. 22:47 (CEST)

- preparations - create a volume and upload a Debian netinstall image to it
tingo@bite:~$ sudo virsh vol-create-as iso debian-10.10.0-amd64-netinst.iso `stat -Lc%s debian-10.10.0-amd64-netinst.iso` Vol debian-10.10.0-amd64-netinst.iso created tingo@bite:~$ sudo virsh vol-upload debian-10.10.0-amd64-netinst.iso ./debian-10.10.0-amd64-netinst.iso --pool iso
verify that the new image is available
tingo@bite:~$ sudo virsh vol-list iso Name Path ----------------------------------------------------------------------------------- debian-10.10.0-amd64-netinst.iso /var/lib/iso/debian-10.10.0-amd64-netinst.iso debian-9.1.0-amd64-netinst.iso /var/lib/iso/debian-9.1.0-amd64-netinst.iso
