Install VMware ESX 4.0 vSphere in VMware Workstation 7

Tuesday, January 5th, 2010

Using a laptop with 4GB of RAM, trying to install ESX 4.0 Update 1. Allocated 2GB RAM to the virtual machine but receiving the following error when trying to power it on:

Not enough physical memory is available to power on this virtual machine with its configured settings.
To fix this problem, decrease the memory size of this virtual machine to XXXXMB, or adjust the additional memory settings to allow more virtual machine memory to be swapped.
Alternatively, do you want to temporarily reduce the memory size of the virtual machine from 2048MB to XXXXMB? Reduce Memort | Do Nothing

The only option of any use is of course “Do Nothing”. ESX 4.0 won’t install without a minimum of 2GB of memory.

To fix the issue and allow the virtual machine to power on with its allocation of 2GB memory: In Workstation, go to Edit -> Preferences -> Memory tab then increase the Reserved Memory slider up to the desired amount of memory. I increased it to exactly 2048MB and the ESX 4.0 virtual machine could be powered on.

Also tested with lower values and it will also work – it depends on the Additional Memory setting. The default option is to ‘Allow some virtual machine memory to be swapped’ (switching to the ‘Fit all virtual machine memory into reserved host RAM’ option, will result in the VM failing to power on if the Reserved Memory allocation is lower than the amount of memory allocated to the virtual machine).

A VMware Holiday

Sunday, December 20th, 2009

Between Christmas and the New Year, I plan to do a VMware ESX 3.5 cluster upgrade to vSphere. This will be 4 hosts in an HA/DRS cluster all upgraded to vSphere / ESX 4.0 U1.

The process should be similar to a regular host upgrade: Virtual Center (oops, vCenter), followed by the hosts, followed by the VM’s (tools and virtual hardware). There are a few different options when it comes to the upgrade including Update Manager, ESX host update utility, using install media at the console, … Will post again with the upgrade details.

VCP4 Exam Post Mortem

Sunday, November 22nd, 2009

Long story short, I passed.

Exam was fair, tougher in my opinion than the VI3 exam which is a good thing since I managed to pass that exam without ever having used ESX, Virtual Center, etc outside of the required training course. There were a lot of good questions in the VCP4 exam that require you to actually know how to use ESX, vCenter, Update Manger, etc and not just be able to recall facts or figures. That said, it’s well worth studying the configuration maximums and install, administration, upgrade guides, etc as many questions also come from there. I heard there was less memory test type questions (like configuration maximums) in this exam but I definitely got a few in my questions set.

I was time poor in studying for this exam and really would have liked more practical knowledge of vSphere before going into it. The study resources I previously posted about were brilliant. Simon Long’s blueprint links and Forbes Guthrie’s vReference card are outstanding resources and I found myself continually going back to them. Know the exam blueprint and study what it indicates you should study.

But most importantly, to understand vSphere and what the exam wants you to know, you need to use it. So download ESX 4, vCenter, Update Manager, VMware Data Recovery and get them setup in a lab and use the 60 days of evaluation period to really understand how it all works. You might not be able to do everything (not everyone has FC, iSCSI and NFS boxes lying around), but most features you can get a good overview of by setting up a single host or even better two virtualized hosts.

VCP4 Upgrade. Tick Tock.

Friday, November 13th, 2009

Since VMware are allowing currently certified VCP3′s to do the VCP4 exam before December 31, 2009 without having to take the Install, Configure, Manage course AND are offering a free 2nd shot [link], I have booked in my exam. Giving myself about 2 weeks to study the new stuff in vSphere / vCenter Server and refresh everything VI3.

Study will be based around the following:

Beyond that I’ll get some practical time in running up ESX hosts, building vCenter, using Update Manager, trying to test as much as possible of the new features (vMware FT, Distributed vSwitches, DPM, etc).
