Virtualization platform matrix

Found this matrix over virtualization solutions and at this site you can get quite a good overview what the competitors can offer and what is enough for your virtualization solution. Still VMware is a bit ahead but Microsoft and their Hyper-V solution with System Center are getting closer.

I believe that every virtualization platform need to be thoroughly designed and thought through not just on the  technical level but also at the organisation and operational levels. As they write in this book, “Design is making the VMware vSphere environment do the things it needs to do”

I really want to recommend this book as it covers much more than just the technical bits on how to tweak the vSphere installation.

Playing around with Powershell and SCVMM 2012 beta and Hyper-V R2


Have been playing a little with powershell and SCVMM2012 and with these simple lines i add 64 SCSI vhd drives á 4 GB each and then delete them all while the VM is running

$VM = Get-VM -Name "VMc2test"

for ($i=0;$i -le 63;$i++){

$vhdfilename = "vhdtest" + $i
New-VirtualDiskDrive -VM $VM -Dynamic -Filename $vhdfilename -sCSI -Size 4000 -Bus 0 -LUN $i

and to delete them

$vhds = @(Get-VirtualDiskDrive -VM vmc2test | where {$_.BusType -match "SCSI"})

foreach ($vhd in $vhds){

Remove-VirtualDiskDrive -VirtualDiskDrive $vhd


and why did i select the ones that had SCSI in the remove part, well the system vhd where the OS resides is on the IDE controller so i can safely assume that the OS will still be accessible, as some of you already know in Hyper-V the boot volume must reside on a IDE controller for the VM to boot.

Novell Platespin Recon 3.7.2 bug causes abnormal PEAK CPU

Today i got help from the Novell support for a Platespin Recon installation, it was a installation that was upgraded from 3.7.1 and after that when i created consolidation scenarios the PEAK CPU got values that was not normal, for some of the servers it was 4x or more of maximum cpu speed, which of course is impossible.

after a quick response from the support-team i got a patch  bug-680478_Patch as you can read below it fixes some issues that you can encounter


The following issues are addressed by this patch

1. Bug 681173  – High CPU value for Processor peak values
2. Bug 680865  – Recon: inconsistant CPU utilization reporting
3. Bug 680478  – Recon 3.7.2 Servers don’t consolidate in virtualization scenario
4. Bug 676315  – Recon 3.7.1 – Values in Scenario for CPU and network are not realistic


so if you encounter very strange values in your reports or in your scenarios, open a case with the novell support and they should give you the patch instantly


HP Bladesystem Virtual Connect FW update 3.17

Ett par veckor sen har detta dykt upp men det kan ändå poängteras och sägas en gång till att det kommit en uppdatering till Virtual Connect och specifikt för FlexFabric och Flex-10 VC-moduler som man har i sitt bladchassi.

Uppdateringen som går att läsa mer om här avhjälper en del besvärande buggar och det referas även till två pdf dokument där man kan se vilka fw och rompacks man bör ha på sina blad/oa och även de drivrutiner som bör appliceras för att få så störningsfri drift som möjligt.

Trevligt FW-helg
