Management Interface

"The VMware Server Web-based management interface. Install on your VMware Server system to enable control from a Web browser. Includes downloadable VMware Server Console installation files."

Web management console (34MB): 

wget http://download3.vmware.com/software/vmserver/VMware-mui-1.0.4-56528.tar.gz
tar -zvxf VMware-mui-1.0.4-56528.tar.gz
cd vmware-mui-distrib/

# Uninstall with: /usr/bin/vmware-uninstall-mui.pl
# service: httpd.vmware
# Runs on tcp port 8222 - http://server:8222

My comment: this has VERY little management and configuration options. Not required and not worth the install. The Windows or Linux Server Client is all you will need.

Remote Console

Remove console connections use TCP port 902.

CLI Commands

List running VMs: 

vmrun list

Start/Stop VM: 

vmrun start/stop <path to vmx file>.vmx

Alias vm to vmrun: 

#/etc/bashrc
alias vm="vmrun"

Shared Disk

For a cluster shared disk configuration, add another "Hard Disk" (Create a new virtual disk) to one of the node's VM configuration. Specify SCSI disk and under the advanced options select Independent and Persistent Mode disk option and place on a second virtual SCSI controller (ie. SCSI 1:0). After creation select the Advanced options again for the disk and disable the "write caching". Edit the .vmx to enable the shared disk options (below). Next, add the same disk to the other node's VM configurations (Use an existing virtual disk) making the same changes (independed, persistent, disable write cache) and to their .vmx files. 

disk.locking = "false"
diskLib.dataCacheMaxSize = "0"

scsi0.present = "TRUE"
scsi0.virtualDev = "lsilogic"

scsi0:0.present = "TRUE"
scsi0:0.fileName = "node-os-disk.vmdk"
scsi0:0.redo = ""

scsi1.present = "TRUE"
scsi1.virtualDev = "lsilogic"

scsi1:1.present = "TRUE"
scsi1:1.fileName = "cluster-share.vmdk"
scsi1:1.writeThrough = "TRUE"
scsi1:1.shared = "TRUE"
scsi1:1.mode = "independent-persistent"
scsi1:1.redo = ""

scsi1:2.present = "TRUE"
scsi1:2.fileName = "cluster-quorum.vmdk"
scsi1:2.writeThrough = "TRUE"
scsi1:2.shared = "TRUE"
scsi1:2.mode = "independent-persistent"
scsi1:2.redo = ""

The missing items from the install are:

  • Configuring disks on separate bus from OS disk (ie scsi1)
  • disk.locking = "false"
  • diskLib.dataCacheMaxSize = "0"
  • scsi1:2.shared = "TRUE"
  • scsi1:1.writeThrough = "TRUE"
  • scsi1:2.mode = "independent-persistent"

Time Synchronization

The ntp daemon will not be able to keep sync with an ntp server because of the extreme jitter caused by the randomly slow/fast clock.

To help reduce this time problem:

  • Install VMware Tools (keep clock from going too slow):
  • Append to the kernel boot options (keep clock from going too fast):
clocksource=pit
clocksource=pit nosmp noapic nolapic
  • Add the following failsafe script to crontab:
crontab -e
* * * * * /usr/sbin/ntpdate [NTP_SERVER_IP] > /dev/null
  • If you have cpu throttling try the following (get cpukHz from /proc/cpuinfo):

/etc/vmware/config 

host.cpukHz = 1000000
host.noTSC = TRUE
ptsc.noTSC = TRUE

Notes

Clock in a Linux Guest Runs More Slowly or Quickly Than Real Time:

CentOS NTPd Problem (Mostly) Resolved Talks about taking this a step further:

"And the time still isn’t synchronized to the level I would like, but it does stay within a minute or so of the rest of the network (well within the 5 minute gap required in order for Kerberos authentication to work)."
# Boot options
noapic nosmp nolapic clock=pit acpi=no

# ntpd.conf options
#server 10.161.101.1
#server 127.127.1.0
#fudge  127.127.1.0 stratum 10
server W.X.Y.Z burst iburst

Kernel parameter clock is depreciated, use clocksource instead: 

#reported by 'dmesg'
Kernel command line: ro root=LABEL=/ clock=pit
Warning! clock= boot option is deprecated. Use clocksource=xyz

#So use this instead:
clocksource=pit nosmp noapic nolapic


References:

Talks about setting the boot option "clock=pit"
Discusses recompiling the kernel with a higher timer interrupt rate
"Time synchronization problems are a common VMware guest configuration issue which occur when VMware Tools have not been installed on the guest and configured according to VMware's instructions."
  1. Install VMwareTools in the guest OS, following VMware's instructions for the target OS.
  2. On the HOST machine, locate the <session name>.vmx VMware session configuration file for the guest OS in question, and add a line which reads:
    • tools.syncTime = "TRUE"
  3. Restart guest session

VMware Tools


Mount install CD from command line

Snapshot

NOTE: make sure to be in the folder and use "./" for path.

Create snapshot: 

vmrun snapshot <path to vmx file>
vmrun snapshot ./virtualmachine.vmx

Delete snapshot: 

vmrun deleteSnapshot <path to vmx file>

Rever to snapshot: 

vmrun revertToSnapshot <path to vmx file>


VMware Workstation: Command Line Application:

Create a snapshot of a virtual machine: 

snapshot [Path to .vmx file] [snapshot name]

List all snapshots in a virtual machine: 

listSnapshots [Path to .vmx file]

Remove a snapshot from a virtual machine: 

deleteSnapshot [Path to .vmx file] [snapshot name]

Go to a snapshot in a virtual machine: 

revertToSnapshot [Path to .vmx file] [snapshot name]
revertToSnapshot [Path to .vmx file] [snapshot name1/snapshot name2]

Revert Notes:

If a snapshot has a unique name within a virtual machine, you can revert to that snapshot simply by specifying the path to the virtual machine's configuration file and the snapshot name: [Path to .vmx file][snapshot name]

If several snapshots have the same name, you can still specify a snapshot by including a "pathname" for the snapshot name. A pathname is a series of snapshot names, separated by forward slash characters ("/"). Each name specifies a different snapshot in the tree, and together the names in a pathname will specify a path from the root snapshot to the snapshot you are naming.

For example, suppose you include the pathname "snap1/snap2". This will identify a snapshot named "snap2" that was taken from the state of a root snapshot named "snap1".

Because the forward slash can be used in a pathname to specify a particular snapshot in the revertToSnapshot command, it is recommended that you avoid using the slash character when you name a snapshot, since this will make it difficult for you to predict which snapshot a pathname will identify.

VMware Server 1.0 is now Free

VMware Server 1.0 now free:

"As was announced back in February, VMware is now giving away one of its flagship products, VMware Server (formerly GSX Server). The free OS virtualization server makes it possible to run multiple operating systems simultaneously on top of a host OS, which can eliminate dual-booting, make installing or testing potentially dangerous apps risk-free, or keeping around a copy of your old system when you reinstall Windows. VMware Server 1.0 is available for Windows or Linux."

VMware's GSX Server to go freeware:

"According to CNet, VMware has announced that it's going to start giving away its GSX Server product for free. GSW Server, which currently starts at $1,400, is "enterprise-class virtual infrastructure for departmental server consolidation and streamlining development and testing operations," which without the buzzwords means it will let you run lots of operating systems simultaneously on not a lot of hardware for a lot of users. (Take a look at VMware's GSX Server FAQ for more specifics.) VMware is making GSX Server free in hopes that free users will get hooked and upgrade to the even-higher-end ESX Server. Their consumer-grade product VMware Workstation, however, will not be experiencing a price change of its own."

"VMWare has announced the release of VMWare Server 1.0 for FREE. Formerly known as GSX server, this product allows you to take a reasonably powerful server (say a box with two processors and 4 GB of memory) and lets you serve up virtual machines."
  • Try new operating system
  • Test your software
  • Set up an office quickly
You could have your people on the ground go buy a server from the local computer store (or ship one, whatever), and ship them the DVD with your images on it (or a hard drive).

Clone Virtual Machine

How to clone virtual machine with VmWare Server:

Example copy "db1" to "db2" vmware files in 

/var/lib/vmware/Virtual Machines

copied entire db1 directory to new one: 

cd /var/lib/vmware/Virtual Machines
cp -ax db1 db2

rename virtual machine’s disk image (maybe it is not necessary but I decided that it would be better to perform this operation): 

cd db2
/vmware/bin/vmware-vdiskmanager -n db1.vmdk db2.vmdk

rename virtual machine config and change disk image name in this config file: 

mv db1 db2
sed -i 's/db1.vmdk/db2.vmdk/' db2

Now we can start this new machine with VMware server console, it would ask as to change machine’s UUID (which is machines MAC address)

This program cannot tell for sure, but you may need to upgrade libc5 to glibc
before you can run VMware Server.

To solve: 

yum install libXtst libXrender
# or
yum install libXtst libXext libXt libICE libSM libXrender

BusLogic vs LSI Logic SCSI Adapters

VMware released a great whitepaper about virtual I/O architectures and performance impacts:

"The storage subsystem is a critical determinant of system performance. The key to good storage performance is to identify factors and system configuration settings that affect performance and understand how to set these in order to achieve the best results. The basic determinants of performance are the operating system, the data transfer size, and the access pattern. In the virtual machine environment, the drivers for the available virtual adapters are also a factor. VMware ESX Server virtual machines can use virtual BusLogic and virtual LSI Logic SCSI adapters. The default driver for a virtual machine depends on the guest operationg system. for example, Windows 2000 guests use the Microsoft-supplied BusLogic adapter by default, while Windows Server 2003 guests use the LSI Logic adapter by default. This document provides a characterization of storage performance for a VMware ESX Server system with an EMC CX500 SAN as the storage back end. The goal is to provide performance data and system resource utilization at various load levels. Throughtput, I/O rate, and response time for various data sizes and access patterns provide sizing guidelines. This baseline data is expected to help debug performance problems and facilitate server consolidation for I/O intensive workloads."
