Phoenix was our secondary VM host. It rose from the ashes of europa and xen2. It has since been decommissioned because the computer was crashing too often, and from it's ashes rose Felix..

Phoenix has older drives than eevee, but several of them have never been used prior to being installed in Phoenix. Additionally, all 4 drives, which are 1 TB each, have been configured in RAID6 to allow for up to 2 failed drives and provide a total of 2 TB of storage. This is twice the amount of storage as eevee currently has and also twice the tolerance for failure.

Each of Phoenix's CPUs are much older than, but roughly comparable in performance to Bennu's CPU. Thus, Phoenix also has roughly twice the computing power as Bennu.

Setup

Generally, we followed the instructions on the debian wiki.

Things to install

apt install htop vim sudo qemu-kvm libvirt-bin virtinst screen rsync

Network Bridge Setup

In order for the VMs to be on our LAN, a bridge must be set up as follows:

In /etc/network/interfaces:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
auto eth1
auto eth2

auto br0
iface br0 inet static
        address 128.153.145.40
        netmask 255.255.254.0
        gateway 128.153.144.1
        bridge_ports all


After making modifications to this file, you can either restart networking (/etc/init.d/networking restart, systemctl restart networking, etc.) or use ifup br0

Bridging interfaces will cause the interfaces used to not have an ip address even if they are up. The bridge interface will contain an ip address.

Automated backups

Phoenix and Bennu will perform weekly backups of each others running VMs. This is a WIP.

Current VMs

Main VMs that are currently on Phoenix include

Recovery of Drives

It is possible to recover the drives.
