Breaking VMware Update Manager

You should believe that the VMware Update Manager was capable of handling missing files. But no, it does not. I removed a couple of files from the repository by simply pressing delete on them. These files were part of a host upgrade baseline and were no longer needed.

After the delete operation, I can no longer scan the hosts successfully. The scan failes with “invalid state” even though the event list says the scan was successful. After tried restarting the update manager service and vCenter, I guess the next step is a full reinstall since I do not like poking around in the database..

Performance monitoring problem

My new R710 running ESXi 4.0 has one problem: When the CPU load comes close to maximum, all performance monitoring for the host failes. Only a few, random monitoring requests comes through, making the resource graphs in vCenter look pretty ugly.

Automatic installation of ESX 4.0

Mike La Spina has written a nice post about automatic installation of ESX 4.0 hosts utilizing PXE, kickstart and a lot of scripts. Mike has done a nice job creating configuration scripts, making it easy to copy his ideas for use in your own environment.

Auto installation becomes necessary if you need to deploy a large number of hosts. Now, if VMware only could copy Virtual Iron’s way of automatically installing and setting up hosts. My dream is an automatic installation and configuration of ESXi hosts without the need for painful point-and-click-customatization after the host is added to vCenter. Host profiles, as far as I know, solves only half the problem (and yeah, I know that it is possible to achieve this by using some custom scripts)…

Feature requests, take two

It’s been nearly 11 months since I wrote the feature request post where I asked for some features currently missing in VMware. Now, it’s time to see how it went: Read more »

Changing host name and IP address of a vCenter server

I recently had the pleasure of trying to change the host name and IP address of the vCenter server. The old host has two networking interfaces. NIC1 was connected to the Internet while NIC2 was connected to an internal network with IP address 192.168.30.0/24. The vCenter and the plugins were configured to use the internal IP address.

New host: Dell PowerEdge R710

So, it was time to make the virtualization a bit more serious and the same time solve my hosting problem. After a quick survey of the hardware available, I bought a Dell PowerEdge R710: Read more »

vSphere 4.0

So, vSphere is out. I can’t say that I have noticed a huge difference from ESXi 3.5 to 4.0, but a few new features are always nice. Read more »

Dell R200 and vSphere

Yes, the Dell PowerEdge R200 runs vSphere/VMware ESXi 4.0. More details to come as I revive this blog :-)
