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
This is a starter network configuration (for reference)
/etc/netctl/ethernet
Description='A basic static ethernet connection'
Interface=enp4s0f0
Connection=ethernet
IP=static
Address=('128.153.145.43/23')
#Routes=('192.168.0.0/24 via 192.168.1.2')
Gateway='128.153.144.1'
DNS=('128.153.145.3')
Bonded Ethernet
Warning! This requires setup on the managed switches it's connected to!
Bond the Ethernet together
/etc/netctl/bond
Description="A bonded interface"
Interface=bond0
Connection=bond
BindsToInterfaces=('enp4s0f0' 'enp4s0f1')
IP=no
Then set a bridge on that bond for the VM's
/etc/netctl/bridge
Description="Example Bridge connection"
Interface=br0
Connection=bridge
BindsToInterfaces=(bond0)
IP=static
Address=('128.153.145.43/23')
Gateway='128.153.145.1'
DNS=('128.153.145.3')
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 15 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 |
