VMware ESX 4.x

VMware ESXi

See VMware ESXi

What does ESX stand for?

Reference 1

What does ESX stand for? [1]

ESX is an acronym for Elastic Sky X
GSX is an acronym for Ground Storm X

Both names were confirmed by VMware employee JMills in this thread: http://communities.vmware.com/thread/20538

Source: vmfaq.com - What does ESX stand for?

Reference 2

ESX = Elastic or Electric Sky

GSX = Ground Sky

"early days west coast cali hippy advertising thinking from the boys in the states. They dont mean't anything and the X was added for acromyn :)"

Source: Abbreviation ESX

Reference 3

"I thought ESX was named by someone who could spell or had dyslexia - and was meant to be SEX!"

Source: Abbreviation ESX

Reference 4

"As the story goes, the founders of the product coined the names when they were students (hippies) at Berkley. You figure out the rest."

Reference 5

"Today, I saw an article on acronyms on Yellow-Bricks which reveals the secret. Furthermore, there's a link to a video interview with Mike DiPetrillo which elaborates on the matter (about 21:30)

ESX: Elastic Sky X
GSX: Ground Storm X

The two names was invented by some marketing people hired by VMware. VMware didn't like it too much so they shortened it to ES and GS and the X was added just to make it sound more technical!"

Source: Virtual Infrastructure Tips - VMware: What does ESX stand for? - http://www.vi-tips.com/2010/08/what-does-esx-stand-for.html


"Of course the big question is where the “X” comes from in ESX, GSX etc. To be honest I don’t know but according to VMware old-timer Mike Di Petrillo (source is this interview (21:30) by Rodney Haywood) the X had been added by an Engineer to make it sound technical and cool!"

"Lastly Mike discusses the feature of VMware that he thinks is just way cool, after all he has been working with virtualization for longer than most of us. Also Mike reveals how ESX got its name. Do you know what the three letters stand for?"

COS

Service Console OS (COS)

The ESX userspace environment, known as the "Service Console" (or as "COS" or as "vmnix"), derives from a modified version of Red Hat Linux, (Red Hat 7.2 for ESX 2.x and Red Hat Enterprise Linux 3 for ESX 3.x). In general, this Service Console provides management interfaces (CLI, webpage MUI, Remote Console). This VMware ESX hypervisor virtualization approach provides lower overhead and better control and granularity for allocating resources (CPU-time, disk-bandwidth, network-bandwidth, memory-utilization) to virtual machines, compared to so-called "hosted" virtualization, where a base OS handles the physical resources. It also increases security.

NFS Mount

esxcfg-nas -a newpu -o newpu -s /home/esx

Service Console

???

Switch Interace: 

esxcfg-vswif -a vswif33 -p "private cos" -i 192.168.200.10 -n 255.255.255.0

Service Console: 

esxcfg-vmknic --add --ip=DHCP --netmask=255.255.255.0 "Service Console"

Managed Object Browser (MOB)

The MOB is a Web-based server application hosted on all ESX hosts and vCenter Server systems. The MOB lets you explore the objects on the system and obtain information about available properties and methods. It’s a great tool for investigating server-side objects and for learning about the VMware Infrastructure object model. [2]

Enable SSH Access

  1. Press Alt-F1 to access the console
  2. Login as a 'root' at the console
  3. Edit /etc/ssh/sshd_config 
    • vi /etc/ssh/sshd_config
  4. Navigate to the line saying PermitRootLogin no and change it to Yes. 
    • PermitRootLogin Yes
  5. Restart SSH service: 
    • service sshd restart

Log files

ESX Server host agent log – /var/log/vmware/hostd.log – Contains information on the agent that manages and configures the ESX Server host and its virtual machines (Search the file date/time stamps to find the log file it is currently outputting to). 

/var/log/vmware/hostd.log

NOTE: hostd.log also contains the build and version number

Service Console – /var/log/messages – This log is the log from the Linux kernel (service console), which is generally only potentially useful in the case of a host hang, crash, authentication issue, or 3rd party app acting up. This log has NOTHING to do with virtual machines. The SERVICE CONSOLE (red hat kernel) has NO awareness of the VMs (worlds) running on the VMKERNEL. 

/var/log/messages

esx.conf

vpxa.log

Which ESX log file | VMwarewolf 

/var/log/messages - only COS related things (not very useful)
/var/log/vmkernel - good log of vm startup and storage usage, and other errors
/var/log/vmware/hostd.log - very verbose log of systems messages

Maintanance Mode

Below is the command which you will have to execute from SVC Console to enter host into maintenance mode 

vimsh -n -e /hostsvc/maintenance_mode_enter

To exit maintenance mode 

vimsh -n -e /hostsvc/maintenance_mode_exit

Now next question is how I check whether host is in maintenance mode.Here is it… 

vimsh -n -e /hostsvc/runtimeinfo | grep inMaintenanceMode | awk '{print $3}'

Removing Password Requirements

VMware KB: ESX and ESXi 4.x password requirements and restrictions - http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1012033

ESX 4.0

/etc/pam.d/system-auth-generic

  1. Change the line:
password   required   /lib/security/$ISA/pam_passwdqc.so   min=8,8,8,7,6 similar=deny match=0
  1. to:
password   required   /lib/security/$ISA/pam_passwdqc.so   min=0,0,0,0,0 similar=deny match=0
  1. or
password   required   pam_cracklib.so try_first_pass retry=3
  1. or - my favorite:
password   required   /lib/security/$ISA/pam_passwdqc.so   min=8,8,8,7,6 similar=deny match=0 enforce=none

ESX 4.1

/etc/pam.d/system-auth 

# change
 password        required        /lib/security/$ISA/pam_passwdqc.so          min=8,8,8,7,6 similar=deny match=0
# to
 password        required        /lib/security/$ISA/pam_passwdqc.so          min=8,8,8,7,6 similar=deny match=0  enforce=none

Add a "Virtual Machine Port Group" Port Group for VM usage: 

# esxcfg-vswitch --add-pg "VM Network" kswitch
esxcfg-vswitch -A "VM Network" kswitch

Add "Service Console Port" Port Group: 

esxcfg-vswitch -A "Service Console" kswitch  # "Service Console" can be what ever you would like (ie SConsole)

# esxcfg-vswitch -l
Switch Name      Num Ports   Used Ports  Configured Ports  MTU     Uplinks

Create a Service Console Virtual Switch Interface in the "Service Console" port group 

# esxcfg-vswif -a -i DHCP -p "Service Console" vswif0
# esxcfg-vswif --add --ip 10.50.2.100 --netmask 255.255.255.0 --portgroup "Service Console" vswif0  # must be named vswif[0-99]
esxcfg-vswif --add --ip DHCP --portgroup "Service Console" vswif0  # must be named vswif[0-99]

Set default gateway in /etc/sysconfig/network (only if assigning static IP) 

GATEWAY=10.50.2.1

Restart network service (so default gateway takes affect) 

service network restart

NOTE: Now you can SSH into the system

Add a "VMkernel Port" for NFS: 

esxcfg-vswitch -A "VMkernel" kswitch
esxcfg-vmknic -a -i DHCP "VMkernel"    # vmk0
esxcfg-vmknic -l

# static method:
esxcfg-vmknic -a -i 10.50.2.150 -n 255.255.255.0 "VMkernel"    # vmk0
esxcfg-route 10.50.2.1


Add NFS NAS: 

esxcfg-nas -a newpu -o newpu -s /home/esx

Issues:

I get the following error when I try to connect from vCenter Server: 

Call "Datacenter.QueryConnectionInfo" for object "MyDC" on vCenter Server "VCENTERSERVER5" failed.

Cause:

Solution:

  • Check the IP configuration, such as default gateway for the Service Console.

Changing the IP address of service console in ESX 3.x : VMblog.com - Virtualization Technology News and Information for Everyone 

esxcfg-vswif -a vswif0 -p Service\ Console -i 10.1.1.1 -n 255.255.255.0 -b 10.1.1.255



[root@ws-193-8 ~]# esxcfg-route -a default 10.193.1.254
Setting default route for VMkernel to 10.193.1.254
Error: Cannot set gateway or routes until kernel TCP stack has at least 1 IP address


How to change IP address of your ESX Server | ESX Virtualization 

esxcfg-vswif -d vswif0

esxcfg-vswif -a vswif0 -p “Service Console” -i 192.168.0.100 -n 255.255.255.0 -b 192.168.0.255

default gateway 

vi /etc/sysconfig/network

Then you need to restart the interfac. Do a “esxcfg-vswif -s vswif0″ (this will disable the vswif0 interface) and “esxcfg-vswif -e vswif0″ (this will enable the vswif0 interface)
