The Host Setup

The host machine has the following specification:

  • CPU :
    • Athlon X2 4850e (2.5GHz) dual core
  • Memory
    • 8Gb RAM
  • Storage
    • 2 x 500Gb drives.
  • IP addresses
    • 1 IP for the host.
    • A /27 allocation (32 addresses) for the guests.

The host machine is setup with software RAID, and uses LVM for storage. This provides protection against a single drive failing - but doesn't help if the motherboard is fried, a powersupply explodes, or meteor strikes the hosting facility. i.e. Take regular backups. Yourself.

Per-User Specification

The resources are split up such that each user has a single guest with:

  • Memory
    • 1Gb RAM
  • Storage
    • 50Gb.
  • IP addresses
    • 3 IP Addresses.

i.e. The resources of the machine were divided into eight equal shares, and seven of them are allocated to our seven users. The eight share is assigned as overhead for the host.

Network Setup

There is nothing terribly complex about the network setup - each machine has a number of IP addresses allocated to it.

Currently the range is assigned as:

grimoire  80.68.85.37-39
mgdm      80.68.85.40-42
nsa       80.68.85.43-45
skx       80.68.85.46-48
joey      80.68.85.49-51
cernio    80.68.85.52-54
ore1      80.68.85.34-46 [*]
ore2      80.68.85.55    [*]

  [*] = Half-sized guests.

With the current setup we can have IPv6, but that has not yet been configured.
