VMworld roundup – day 1

Well, last night we had a great party. We did meet with some other colleagues and customers/friends in the evening.

This morning we woke up and…the weather was excellent here in Cannes! We (Geert Verbist over at virtual-scene.info, Guy and myself) attended the general keynote and some sessions.

For the first time (well, that is not counting partner day) Paul Maritz actually used the term vSphere to describe what will be the VDC-OS of the future (this will be the name of the ESX/VI 4.0 suite of products that will be released in the first half of 2009). The 2 main keywords of this VMworld: VDI/vClient solutions and the internal/external (v)Cloud/VDC-OS

Next, I attended a great session on VMware with NetApp integration. The things these guys are doing (combined with the next-gen vStorage API) are just amazing. Soon we will be able to offload all Snapshot/Clone/Thin Provisioning/… tasks to our storage. At last! What used to take minutes (as in: deploying a template is just a copy operation of a .vmdk) is now done in seconds! Needless to say the demo’s were quite impressive.

Oh yes, did I mention Multipathing in vSphere? I didn’t? Well, listen to this: it will be possible to configure the optimal path to your san (using vStorage API) with just 1 click of the mouse: “Apply optimal path configuration” (or something like that, I don’t remember the exact command). Gone are the days of manual multipathing. Anyway, I hope all other vendors will follow NetApps example and integrate all these nice toys in their products.

Next up was the first 3rd party vNetwork Distributed vSwitch: Cisco Nexus 1000V, a (software) plug-in to ESX that creates an advanced vSwitch version built on Cisco NX-OS. We will finally see a managed vSwitch on ESX with full configuration, monitoring and security options! The VEM (Virtual Ethernet Module, or the vSwitches themselves) are managed by a VSM (or Virtual Supervisor Module, a VM or hardware appliance that manages all VEM instances and that tightly integrates with vCenter).

Don’t worry: if the appliance fails, all configuration states are unchanged until the VSM is revived/restored. You can manage the switches as you can manage a “real” Cisco switch. As this is a distributed switch, you must only create it once per cluster. So adding a new ESX host will be a breeze(oh yes, did I mention host profiles ;))

Another session that got my attention was the one about SRM design best practices. Glad to here we already set-up SRM by the book.

Last (but definitely not least) we checked out a session from the (in)famous Brian Madden himself: VDI versus Terminal Services. In his (controversial) typical way he compared VDI to TS as being both SBC (server based computing) with the same problems/advantages since Citrix launched WinFrame (now called XenApp) for NT 3.51 in 1997.

His conclusion: with TS, you currently get more bang for the buck (or should I say more users per server?). HOWEVER: if you see how fast the VDI space is growing and the fact that there is tremendous competition amongst Citrix, Quest and VMware he predicts that by June 2010 all major problems with VDI as such will be gone. We’re thinking graphical enhancements (Terradici, HP RGS, ....), more users per server, thin provisioning on your SAN, etc..). Yay to TS! Yay to VDI!

Next up: the VMware Benelux party with 250+ Benelux people. Happy times and kisses from Cannes and see you tomorrow!

First day at VMworld Europe 2009

Ok, so we arrived early @ Nice this afternoon, took the bus to the Palais des festivals in Cannes and went through the registration process. All settled then! Tomorrow we’ll have partner day (and the Benelux party of course!) so stay tuned for some nice blogposts on ESX 4.0 (vSphere?), SRM and VMware View!

VMware: Installing Suse Linux Enterprise 10 on ESX

After installing the VMware Tools on our Suse Linux Enterprise 10 guest, we kept losing the network configuration. Apparently, after loading the vmxnet driver there were 2 network cards present.

So here is the workaround:

  • Start yast (or use the gnome desktop to configure yast via the GUI)
  • Click the Network devices link and click on Network Card
  • Leave the default “traditional method with ifup” and click Next
  • Select the current configured card and click the Edit button
  • Write down (copy) the current configuration name (eth-id-xxxxxxx)
  • Click the back button and remove the current configured network card by pressing the delete button. NOTE: only 1 network card should remain
  • Back in yast overview, navigate to Network devices => Network Card
  • Select the card that is not configured and click the Edit button
  • On the configuration name, replace pci-xxx by eth-id-xxxx (written down earlier)
  • Fill out all necessary IP configuration (IP Address, subnet mask).
  • Leave yast and commit your changes
  • Done!

VMware: Stopping a Virtual Machine gone haywire

Sometimes a Virtual Machine can't be stopped via the VIClient. The job just hangs. There are a number of options to stop your Virtual Machine from within the Service Console. Keep in mind that these are last resort options!

  • Stopping the virtual machine by issuing the command vmware-cmd /vmfs/volumes/<datastorename>/<vmname>/<vmname>.vmx stop. This must be done on the ESX host where the Virtual Machine is running!
  • If this does not work, one can issue the following command: vmware-cmd /vmfs/volumes/<datastorename>/<vmname>/<vmname>.vmx stop hard. This will try to kill the Virtual Machine instantly.
  • A final solution is to kill the PID (process ID). Issue the following command: ps auxfww | grep <vmname> to locate the correct PID (BTW: this cannot be done via ESXTOP). The first number to appear in the output is your PID. The PID can be used to terminate the process by issuing kill -9 PID.

VMware: New HA features in VC 2.0.2

As you know, HA is triggered on an ESX host after 15 seconds when it cannot contact it's cluster partners and the default gateway. By Default, all virtual machines running on the ESX host are shut down and restarted on the remaining ESX hosts in the cluster (using a Legato AAM agent to do it's job).

The only thing you could do up until now was changing the default gateway (via the das.isolationaddress option/value set). However, for most companies this is not enough. When a general network maintenance is scheduled, you should disable HA to avoid an unnecessary HA trigger.

New in VirtualCenter 2.0.2 are the following option/value pairs:

  • das.failuredetectiontime = <value> (default 15 seconds)
  • das.isolationaddress2 = <value>

These values can be set under Your Cluster => Edit Settings => VMware HA => Advanced Options.

VMware: Installing Windows XP on ESX using LSI Logic driver

I get a lot of questions concerning the deployment of Windows XP on ESX. By default, ESX will use the LSI Logic driver when deploying a new Windows XP virtual machine. The LSI Logic driver is not found on the CD-ROM media, so Windows XP will not continue with the installation if this driver is not found.

The steps:

  • Create a new Windows XP Virtual Machine
  • Upload a Windows XP .iso file to your datastore/ISOstore (preferably a VLK version) and link it via the CD-ROM options in your Virtual Machine. Make sure it is connected / at power on
  • Go to http://www.lsilogic.com/cm/DownloadSearch.do and search for a driver for the LSI20320-R controller.
  • Extract all files in the symmpi_wXP_1201800.ZIP
  • Use a program such as WinImage to create an LSILogic.flp file and include the extracted files in the .flp image.
  • Upload the newly created LSILogic.flp to your datastore/ISO store
  • Link the .flp file via the Floppy options => use existing floppy image in datastore in your Virtual Machine. Do NOT connect it yet.
  • Power On your Windows XP machine. The installation of Windows XP should begin.
  • During setup, press F6 to select additional SCSI drivers
  • Now is the time to connect your floppy and use S during Windows Setup when prompted to connect to the floppy drive.
  • The LSILogic drive should appear. Press ENTER to continue
  • Setup will continue as normal
  • Install VMware tools
  • Done!

NOTE: when using the BusLogic driver instead, you can download & use a preconfigured .flp file from the VMware site: http://download3.vmware.com/software/vmscsi-1.2.0.4.flp. Follow the same procedure as described above. The driver should be name VMware SCSI Controller in Windows XP.

VMware: how to get more performance counters in VirtualCenter

Ever wondered why you could select gazillion performance counters in real-time, but only 1 or 2 counters when selecting Per Day/Per Week/Per Month/Per Year/Custom? Here is the solution: in the VIClient, go to VirtualCenter Management Configuration and then statistics. By default, the Statistics Collection Level is set to 1 (Basic Metrics).

Ideally, you could set the level to 3 or even 4. After a while, you will notice new performance counters available for selection in the chart options menu! These are great for doing memory sizing/ CPU sizing over a longer period of time. Great huh?

HP: DL580 G5 released - the virtualization monster

HP has released the G5 version of the DL580. This is a lean mean virtualization machine:


  • Up to 4 Quad-Core Intel Xeon Processors with up to 8MB (4x2) shared L2 cache (16 cores in total)
  • Up to 128GB (with 4GB DIMMs, 32 slots!) of 667MHz DDR2 Fully-buffered DIMMs
  • Up to Eleven PCI-Express Slots

This is a great VMware/Viridian/XenSource/... virtualization machine with plenty of room for extra NICs & HBA's. I hope VMware will be able to use this model in their ESXi platform. How hard can it be to stick an extra 32Mb SSD module in this one ;)

WTS: How To Configure Folder Redirection

Patrick Rouse has written a nice little article on the use of folder redirection in a SBC environment.

Folder redirection can limit the amount of data that is copied between the Roaming Profile Share and the Terminal Server at each logon and logoff. This is accomplished by redirecting folders like Desktop, My Documents, and Application Data to a Network Share outside of the Roaming Profile Share, so it is not copied at each logon and logoff.

Citrix: Citrix to acquire XenSource

Holy god, this is breaking news! After rumors on the brianmadden website about Citrix wanting to buy XenSource, there is now an official statement: Citrix has signed a definitive agreement to acquire XenSource.

Citrix’s acquisition of XenSource comes on the heels of a substantial new release of XenEnterprise, the company’s flagship commercial product line. The new XenEnterprise v4 marks a significant milestone. Citrix will thus become one of the major players in the virtualization field (and a direct competitor to VMware & Microsoft).
