Intro

Rules

  • Please ask for an account if you think you need one.
    • Chances are you actually want an account on one of the VMs the machine runs instead.

Instructions

Virtual machine control notes

sudo -u vm_host vboxmanage controlvm mcclellan poweroff

sudo -u vm_host vboxmanage modifyvm mcclellan --memory 2048

sudo -u vm_host vboxmanage startvm mcclellan --type headless

IFS=$'\n'; for host in $(sudo -u vm_host vboxmanage list runningvms | cut -f2 -d'"'); do echo "$host:"; sudo -u vm_host vboxmanage showvminfo "$host" | grep VRDE | head -n3; echo ""; done

Remote control

VMs can have VRDE, a fancy word for RDP use `rdesktop`, or you might get bad sizes


Creating a New VM

  • ssh into Hardac. Switch to user vm_host and download your install media.

sudo su - vm_host

cd Downloads

wget https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.0.0-amd64-netinst.iso (or whatever the current one is)

cd ../VirtualBox\ VMs/newVM

  • Create the VM and give it some memory, a couple CPUs, and the I/O APIC layer to use them.

VBoxManage createvm --name newVM --ostype Debian --register

VBoxManage modifyvm newVM --memory 1024

VBoxManage modifyvm newVM --cpus 2

VBoxManage modifyvm newVM --ioapic on

  • Set up network adapter.

VBoxManage modifyvm newVM --bridgeadapter1 eth0

VBoxManage modifyvm newVM --nic1 bridged

  • Create a harddisk. Size is in megabytes.

VBoxManage createhd --filename newVM.vdi --size 20000 --format VDI

VBoxManage storagectl newVM --name "SATA Controller" --add sata --controller IntelAhci

VBoxManage storageattach newVM --storagectl "SATA Controller" --port 0 --device 0 --type hdd --medium newVM.vdi

  • Create a DVD drive and mount the install media.

VBoxManage storagectl newVM --name "IDE Controller" --add ide --controller PIIX4

VBoxManage storageattach newVM --storagectl "IDE Controller" --port 1 --device 0 --type dvddrive --medium ~/Downloads/debian-10.0.0-amd64-netinst.iso

  • Enable remote desktop and start the VM.

VBoxManage modifyvm newVM --vrde on

VBoxManage modifyvm newVM --vrdemulticon on --vrdeport 3390

VBoxHeadless --startvm newVM

  • Figure out the IP of the VM. (run VBoxManage showvminfo {{|}} grep MAC and find it in the router.) Make sure your ssh connection has x-forwarding and your client is running an x server (mobaxterm works well on windows). Be logged into Hardac as yourself, not vm_host.

rdesktop 10.13.0.17:3390

  • The debian installer should come up. Follow the instructions. Once it's done and starting to reboot, shut it down (ctrl-C in the session its running in). Eject the installation ISO.

VBoxManage storageattach newVM --storagectl "IDE Controller" --port 1 --device 0 --medium "none"

  • Set it to automatically start, and then start it again,

VBoxManage modifyvm newVM --autostart-enabled On

VBoxManage startvm newVM --type headless

  • Almost done. SSH into it as your user.

su

apt-get install sudo

usermod -aG sudo yourUser

  • Log out and back in. Done!

Maintenance Info

Weekly

  • Check filters for buildup; wash if needed

Usage Notes

It's now running https://etckeeper.branchable.com/

Changes to /etc/ should get autocommitted daily? Better yet, you should commit changes with `sudo etckeeper vcs git diff` and such.

Power Use

Google Sheets

From Matt Gardeski: These are all estimates based on measurements of equivalent parts. If someone wants to do some actual measurements on the hardware we're running, please do. I think the MARS box and the HP have power monitoring built in to the server management hardware.
