New Virtualisation Website Launched!
Hi All, I have just launched my new website http://www.elasticsky.co.uk
Lots of info on the VCP, practice exam questions, video demos, and more to be added.
Please check it out!
It is a common requirement for all servers in a solution, to have the same system time. This can be achieved using NTP service.
To synchronise a client machine with a time source or list of time sources (10.10.10.1, 10.10.10.2, 10.10.10.3),
go to command line
w32tm /configure /manualpeerlist: “10.10.10.1,0×1, 10.10.10.2,ox1 ,10.10.10.3,0×1 ” /update
net stop w32time
net start w32time
To check time between source
w32tm /stripchart /computer:10.10.10.1
Note: UDP port 123 for NTP is required.
On Installation Windows 7 requires licence activation. By default the grace period to do this is 30 days.
If for legitimate reasons this needs to be extended, it is possible to reset this a maximum of 3 times. Resulting in a total 120 days grace period.
This option is activated by running a command prompt session in administrator mode and entering the following;
slmgr.vbs -rearm
A message box will be displayed and the machine will need to be restarted.
This is a Microsoft supported option, and does not violate the EULA
This also applies to windows vista.
From time to time the management and host agents running on an ESX host may need a restart.
This is normally a pretty safe procedure. However very rarely (I have found), a restart of the host agent may fail,
Example output
Stopping VMware ESX Server Management services:
VMware ESX Server Host Agent Watchdog OK
VMware ESX Server Host Agent
To resolve this without an outage to the guest machines, start another SSH session
service mgmt-VMware status
VMware-hostd (pid XXXX) is running…
This will confirm the service is running.
From here, identify the host process by using grep
ps -ef | grep vmware-hostd
then kill the process using the kill command
kill -9
From here, restart the managment services again. This should allow the host to reconnect to the virtualcentre.
