Hydra is our newest VM host (as of September 2016)
Contents
Install
Do a basic debian install with the hard drives software raided in RAID 6, all of the device as /, then continue below
Install Packages
apt install htop iotop iftop lm-sensors vim sudo qemu-kvm libvirt-bin virtinst screen rsync tmux p7zip
Change SSHd to use port 13699 instead of port 22. See
/etc/ssh/sshd_config
Network Configuration
We beed to create a network bridge for the VM's to connect on.
/etc/network/interfaces
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# Auto Configure eth0 and eth1 (our two NIC's - the ethernet over the usb ports is actually a IPMI port)
auto eth0
auto eth1
# Bridge, set the IP here and bridge all the defined ports for communication
auto br0
iface br0 inet static
address 128.153.145.42
netmask 255.255.254.0
gateway 128.153.144.1
bridge_ports all
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 | manage2server |
| 7,8,9,10 | gitlab |
| 24 to 31 | colona-evolutionary-cpu |
Free cores:
6,11,12,13,14,15,16,17,18,19,20,21,22,23
Hardware Information
IMPORTANT - DO NOT BUMP OR JOSTLE CASE
The CPU0 heat sink cooler is not very well mounted. It is mounted properly, however if the server is bumped too hard, the cooler will pop off. Treat the server with extreme care ALWAYS
- 2x 16 Core AMD Opeteron 6376
- 4x 16GB DDR3-1600 ECC RAM
- 5x 2TB Segate Constelation HDD in RAID 6
- 2x Noctua CPU Coolers
- Super Micro MBD-H8DG6-F-0 Motherboard EATX
- Silver Stone 550 Watt 80+ Platinum Power Supply
- Roswell 4u Server Chassis
Good to note is that there are 3 Ethernet ports. Two of them are NIC's (the pair right next to one another) and the one over the USB port is IPMI over Ethernet and has no connection to the kernel. Remote IPMI is disabled, so don't even bother with this.
