Failed to Created Provider vDC in VMware vCloud Director

By wsellers How To, vCloud Director, VMware ESX No Comments »

Last week I was having problems creating a Provider vDC in VMware’s vCloud Director… Here’s the error I was getting

 

Even though the installation was followed step-by-step from documentation, I was still getting this error… After working with VMware Cloud Technical Support, we were able to resolve the issue.   The problem is that when I initially named the VCD System Name I gave it the “exact” name of the VM guest running VCD.

The VCD Installed ran fine — and the installation was successful, — with the exception of errors when creating Provider vCD’s.

So, when you are naming your vCD, give it a unique name—- that will never conflict with the name of a VM guest that exists — or would ever exist…

 

I will post an update here— once the VMware KB article is created and published.

Happy vClouding,
Will

Linux: Extending “root” partiton with LVM

By wsellers How To, Linux No Comments »

Here’s a handy PDF, showing a step-by-step procedure for resizing the “/” root partition on a Linux VM guest.  Please note, that the guest was running a Red Hat based OS.

Restarting the VMware Management service

By wsellers How To, VMware ESX No Comments »
From time to time, you will need to start/restart the VMware Management service.
Here is the command you would use:

# service mgmt-vmware stop
# service mgmt-vmware start (can take up to 1 minute before fully online) 
OR
# service mgmt-vmware restart

This might be a handy command if you are experiencing problems with your ESX host connecting to the VMware Virtual Center server. Also, if you having problems when “kill -9 ” does not stop a VM guest.
Please see this related VMware discussion topic. Be aware of the specific settings your VM guests MUST have before issuing this command.

Thanks,
Will

Could not power on VM : No swap file. Failed to power on VM

By wsellers How To, Site News No Comments »
“Could not power on VM : No swap file. Failed to power on VM” – This issue is caused when a VM guest tries to power on and some other ESX host has one or more guest files open. This is usually due to a crash or fault in the ESX Cluster that HA did not complete successfully.

Here is how to fix:

#1) Login to each ESX’s service console and issue this command: is case sensitive.
For ESX2.x and 3.0.x type: ps -ef | grep vm_guest_name
For ESX3.5.x type: ps -efwww | grep vm_guest_name

If the VM is not running on the ESX host you are on, you will get something like:
root 3483 3217 0 10:38 pts/2 00:00:00 grep vm_guest_name

If you get something like this: (This is the process that has your file open in ESX)
root 1092 1 0 10:33 ? 00:00:00 /usr/lib/vmware/bin/vmkload_app /usr/lib/vmware/bin/vmware-vmx -ssched.group=host/user -# name=VMware ESX Server;version=3.5.0;licensename=VMware ESX Server;licenseversion=2.0 build-82663; -@ pipe=/tmp/vmhsdaemon-0/vmx6a6188c22e804baf; /vmfs/volumes/48729e6e-7cf3b2df-6ca0-001ec9b1b30a/vm_guest_name/vm_guest_name.vmx

#2) You will want to kill the process that is still holding your VM guest files open. You can do this by typing:
kill -9 pid
Example using above VM: kill -9 1092 ( you will notice the pid/process ID in bold)

#3) After doing this, you should be able to Power On your VM guest.
*** Please remember that some HA/DRS issue could have caused this error. Please take a close look at your guest/hosts logs OR call VMware support.

Running VMware VI3 in VMware Fusion for Mac OSX

By wsellers How To No Comments »
Today, I successfully installed VMware Fusion on my Macbook Pro—-then installed a Virtual-Center server and two ESX3.5 servers in a VM guest, running in Fusion. It was really easy. I initially installed 3.5 Update 3—-but had issues with installing the VPXA agent. I downgraded to 3.5 Update 2 with NO problems.
I’ll getting a copy of iShowU in the next few days; and will be doing a screencast to show everyone.
