remarks
- vm will not have autostart 
- storage req: 40GB
	- root size: 10GB (x2 for raid 1)
	- storage size: 5GB (x4 for raid-z2)

install (debian)
$ apt install qemu-kvm libvirt virt-install virt-viewer

install (arch)
$ pacman -S qemu libvirt virt-install virt-viewer

start and set autostart libvirtd
$ systemctl enable --now libvirtd
$ virsh 
troubleshooting: try to load the kvm module with `modprobe kvm_intel`

create storage pool for mirror 
> pool-define-as mirror dir --target="~/.local/mirror/images"
> pool-build mirror
> pool-start mirror
> pool-autostart mirror

create virtual disks
> vol-create-as mirror mirror_root1.qcow2 10G
> vol-create-as mirror mirror_root2.qcow2 10G
> vol-create-as mirror mirror_disk1.qcow2 5G
> vol-create-as mirror mirror_disk2.qcow2 5G
> vol-create-as mirror mirror_disk3.qcow2 5G
> vol-create-as mirror mirror_disk4.qcow2 5G
(exit virsh shell)

get ubuntu iso
$ curl -O https://releases.ubuntu.com/20.04/ubuntu-20.04.2-live-server-amd64.iso 

create the vm
$ virt-install \
--name=mirror \
--memory=2048 \
--vcpus=1 \
--boot uefi \
--location="./ubuntu-20.04.2-live-server-amd64.iso" \
--disk vol=mirror/mirror_root1.qcow2 \
--disk vol=mirror/mirror_root2.qcow2 \
--disk vol=mirror/mirror_disk1.qcow2 \
--disk vol=mirror/mirror_disk2.qcow2 \
--disk vol=mirror/mirror_disk3.qcow2 \
--disk vol=mirror/mirror_disk4.qcow2 \

interface should automatically come up but can also use
$ virt-viewer --domain-name mirror
if vm is on a remote machine
$ virt-viewer --connect qemu+ssh://user@host.example.com/system vmnamehere

for now just have a folder of screenshots
- change name of lvm volume from "lv0-root" to just "root"
troubleshooting: ignore "failed to unmount /cdrom" and just ctrl+c in viewer

login into your created user (from install), change to root, and create password for root
$ sudo su
type in your password
$ passwd
create root password

create zpool (use /dev/disk/by-id/.. instead)
$ apt update
$ apt install zfsutils-linux nginx rsync
$ mkdir -p /mirror/root/.cscmirror
$ zpool create -f -m /mirror/root/.cscmirror cscmirror raidz2 /dev/vdc /dev/vdd /dev/vde /dev/vdf

may already be mounted but just to be sure
$ zfs mount -a


TODO
- configure symlinking from /mirror/root/.cscmirror to /mirror/root 
- configure ssh for push sync
- configure nginx
- configure rsync
- set motd?
- configure FTP (using proftpd)
- Merlin in ~mirror/merlin -> /home/mirror/merlin
- ~mirror/merlin/arthur.py status 
- ~mirror/merlin/arthur.py sync:PROJECT_NAME
- Sync Scripts in ~mirror/bin (and repo, but repo has less)
	- take params local_dir rsync_host rsync_dir
- check out csclub wiki mirror administration for adding a new project and project sync


- ask if can ignore /mirror/newroot
- mirror hosts
