vSphere 5.1 and View 5.1 are finally compatible

As mentioned before, I mentioned vSphere 5.1 currently not compatible with any VMware View version. As of yesterday, VMware has finally released a patch (ESXi510-201210001) to correct the incompatibility issues.

Alternatively you can also download an updated ESXi 5.0 ISO. To download the ISO:

  1. Navigate to the vSphere Download Center.
  2. Click View Download for the VMware ESXi 5.1.0 Installable for your version of ESXi.
  3. On the Product Downloads tab, download VMware-VMvisor-Installer-201210001-838463.x86_64.iso.

Before you go updating your vSphere to the new 5.1 version that was just released, VMware had just released this alert yesterday (9/12) that vSphere 5.1 is currently NOT compatible with any version of VMware View.

vSphere 5.1 is in the process of being certified against VMware View. We recommend that you do not upgrade vSphere above the supported versions listed in the VMware View 5.1 Release Notes.

For further updates and more information on this alert, refer to KB article:
vSphere 5.1 is not compatible with any versions VMware View (2035268).

If you don’t use VMware View, and are ready to upgrade to vSphere 5.1 be sure to check out the Installing vCenter Server 5.1 best practices from VMware.


Improve Linux VM IO performance by disabling IO Scheduler

For a little while now we’ve been seeing RedHat Linux virtual machines performing poorly. Tasks would take considerably longer on the Linux VM’s then other Windows VM’s. After digging around I eventually found that RedHat has it’s own IO scheduler that runs in the background. On a physical box this wouldn’t be a big deal, but as a virtual machine everything is already being processed by VMware hypervisor. The fix, disable the IO Scheduler!

vSphere 5.1 Release Date leaked, maybe?

Looks like Sammy Bogaert over at Boerlowie’s Blog has possibly found the release date of vSphere 5.1… maybe?

I was about to download vSphere Update Manager PowerCLI 5.0.

I followed the main site and wanted to check the documentation first. So I clicked the Documentation button.

vmware update manager

This lead me to the Docs of Update Manager PowerCLI 5.1! That’s right, 5.1! With a release date of 10 September 2012.

vsphere5.1 release date

None of the links for 5.1 work, so no news on any new features…

Guess somebody at VMware was a bit too fast to update the website

Nice find Sammy, guess time will tell if the Sept. 10th date is the actual release date or not.

VMware has just released it’s forth minor update for VMware Workstation 8, bringing it up to 8.0.4. The looks to contain mostly a few bug and security fixes.

  • On Windows hosts, the VMware Workstation user interface sometimes became unresponsive when minimized from full-screen mode if the suggestion balloon was being displayed.
  • On Windows hosts, the user interface sometimes became unresponsive if the application was rendered on an extended display that was abruptly disconnected.
