Tyche is our newest VM host (as of Feb 2017)
Contents
Install
Do a basic Arch install with the hard drives software raided in RAID 1, all of the device as /
Make sure to install GRUB to ALL of the drives and NOT /dev/md0 - also protip: md0 is a partition, not strictly a block device, thus it does not need a mbr and you can mkfs.ext4 /dev/md0 without issue :D
Install Packages
pacman -Syu htop iotop iftop lm_sensors vim sudo qemu libvirtd screen rsync tmux p7zip
Change SSHd to use port 13699 in addition to port 22 (add a line below Port:22 with Port:13699). Edit
/etc/ssh/sshd_config
User Configuration
Add all of the users to the libvirtd and kvm groups that plan to use the VM host
Network Configuration
VM's require a network bridge in order to be able to communicate to the network.
Basic Non-Bond Ethernet

Virtual Machine Core Allocation
These are cores that are allocated to VM's for efficiency.
virsh vcpupin <guestname> <local-core> <host core>
Host cores are between 0 and 31 and local cores are from 0 to n-1 cores
You must run it for each core to each host core
| CPU CORE | ALLOCATION |
|---|---|
| 0 | SYSTEM - DO NOT ALLOCATE |
| 1 | Keyserver, scheduler, honeypot |
| 2 | VRkour, hunterGit |
| 3 | comm, hwiki, Turist |
| 4, 5 | cacti |
| 6, 7 | gmx |
| 24 to 31 | colona-evolutionary-cpu |
Free cores:
6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23
