What is Virtualization

• Virtual Platform allows multiple guest operating
  systems to run concurrently on a single standard
  PC / Server, without partitioning and rebooting
• It emulates a Computer
• It creates a CPU, BIOS, hard disks, memory, and
  all the other components of a regular computer
  for guest OS to run on and use

4
Benefits of Virtualization

• Consolidations of servers.One server to
  administrate
• Running current OSes on complex hardware and
  devices.Some current OSes lack driver support
  on new hardware
• Running legacy OSes (Legacy applications)For
  legacy reasons, old OSes and application can
  still run on modern hardware.
• Good platform for evaluating, testing and
  developing

VMware Commonly used

• VMware is a virtual machine software
• It runs multiple operating systems on a single
  computer
• Its an excellent testing and development
  platform
• Its an enterprise-class server as well
• Create a snap-shot image of the virtual OS at any
  time of operation (Ideal for system recovery if
  guest OS panics after a maintenance work)
• Plus many more advantages

Common Flavors of VMware

• VMware ESX Server Enterprise (Infrastructure)
  ClassIdeal for emulating enterprise class
  servers for live environment.Built directly into
  a custom Linux kernel (Mini Linux) Installable
  CD
• VMware Workstation DesktopIdeal for developers
  (testing and developing)Runs on top of Windows
  Linux
• VMware Server FreewareIdeal for evaluating the
  VMware productRuns on top of Windows Linux

How does SCO Unix benefit from VMware ESX

• Run SCO legacy OSes on modern hardware, i.e
  Openserver 5.0.4, 5.0.5, 5.0.6UnixWare 7.1.0,
  7.1.1, 7.1.2 (OU8)
• Run current SCO OSes on modern and complex
  hardware (where there is lack of SCO drivers)
  i.e64 Bit Servers, iSCSI (Storage), SAN, NAS,
  VMware Cluster, 10GB NIC, 4GB Fibre Host Bus
  Adapter (Emulex, Qlogic)Note SCO drivers for
  some of the above modern hardware are in the
  pipeline ?

Ways to Administer a VMware ESX Server

• VMware Virtual Infrastructure ClientInstalled on
  windows 2000/XP/2003.with this GUI tool as root,
  you can administer anything
• VMware Virtual Infrastructure (VI) Web
  AccesshttpltVMware server IP addressgtOnly
  performs basic ESX functions like controlling
  existing machines (start/stop/pause) and console
  remote access
• Console access to the Service ConsoleDirect
  console access on the VMware serverpress Alt-F1,
  you can get access to the Linux login prompt of
  the ESX service console and login as root
• SSH to the Service Console

Changing the NIC from default to Intel Pro/1000

• As default, VMware ESX Server will used the AMD
  PCnet Family network NIC emulator for the host
  OS.
• This emulator has a very poor network performance
  under several Unix OS'es.
• It is recommended to use the Intel Pro 1000
  gigabit emulator, which has much more better
  network performance then AMD PCnet.

28
Changing the NIC from default to Intel Pro/1000

• To add the Intel Pro/1000 NIC emulator
• Shutdown the Host OS engine (server)
• login in as root on the VMware ESX console
• cd to the location where the host OS image
  resides/vmfs/volumes/ltstorage namegt/lthost OS
  namegt
• edit the lthost OS namegt.vmx file
• add this lineethernet0.virtualDev "e1000
• Restart (reboot) the Host OS engine
• Add the Intel Pro/1000 NIC via Network
  configuration manager.

General Tip in setting up a VMware server and
Guest OSes

• The More Memory you can add to the VMware ESX
  Server the faster the Guest OS can operate.
• VMware Guest OSes runs on the ESX Server Memory
  and not on its CPU
