Host address lookup for server failed: No such host is known.

By wsellers Configuration, VMware ESX No Comments »
This error is caused when your Virtual Center Client application cannot directly (over IP) connect to your ESX host. I see this a lot of times when you are installing the VMVC Client on a new workstation.


The “fix” is very easy:
1) Add your ESX hosts into DNS. -not a bad idea in the first place
*** OR ***
2) Edit your Microsoft Windows hosts file to add your ESX servers for name resolution.
* Found in “C:\Windows\System32\drivers\etc\host” — Just edit with notepad.exe
3) Reopen your client and try again.
Now, if you are traversing a firewall, you may need to open some ports: All the ports needed are open (80, 443, 902, 903).


You may also need to take a look at this VM Communities post, if you are having problems with a “Blank” console screen: http://communities.vmware.com/message/671489 – Also, checkout http://communities.vmware.com/message/533696

- To Enter Maintenance Mode on ESX HOST:
vimsh -n -e /hostsvc/maintenance_mode_enter

How to rename a VM guest, easily.

By wsellers Configuration, VMware ESX No Comments »
Want to rename a VM guest?!? Sure you can manually edit the *.vmx, *.vmdk files — but here is an easier way:


#1) Shutdown your VM guest.


#2) Right click, then Rename in Virtual Center.


#3) Right click, then choose Migrate…. Do a “cold” migration to another Datastore with enough space for your VM guest files, *.vmx *.vmdk’s, etc.


#4) After this finishes, you can move back to the original location, if you want.. — All of your VM guests files will be properly renamed.


#5) Power on your VM guest.
* Only thing you have to watch is to make sure you have enough free disk space on the Datastore you are moving to.


Thanks,
Will
