Actually Windows 8 is not (officially) supported with VMware View, at least not as a virtual desktop.

About the View Client, starting with the 5.2 version it support also Windows 8 as a client (see the official guide). Both the 32 and 64 versions (are supported: Windows 8 Professional and Windows 8 Enterprise) works fine and requirements are just the same as a Windows 7 Client (1 GB of RAM and a x86-based processor with SSE2 extensions, with a 800MHz or higher processor speed).

Also features are exactly the same of Windows 7 Client, including the limit of Wyse MMR that is still working only with Windows XP or Vista Client.

Enterprise Networking Planet has compiled its list of the Top 10 networking experts who are active bloggers and Twitter users (Enterprise Networking Planet’s Top 10 Networking Experts You Need to Follow).

These individuals have varied backgrounds and professional experiences from networking engineer to industry analyst. While a number of them have been or are employed by networking vendors, their blog posts and tweets are their own words and are not endorsed by any of those companies.

Here is my entry:

9. Andrea Mauro (@Andrea_Mauro) has been working with Assyrus Srl, an Italian IT company that specializes in networking, security, virtualization and consulting, since 2000. He holds numerous certifications and is a systems administrator on Linux and Windows OS.

Here are Audrea’s insights on a couple of trending topics for 2013.

  • Networking security: “Network security is still a big challenge and will be also in 2013. I think/hope that we will see more solutions in the virtual environment… NIDS, appliances to have a deep network flow inspection, but also virtual honeypot and honeynet could be an interesting direction applied to virtual machines.”
  • Converged networks: “Converged networks could be a solution to have at least the common Ethernet layer, but in my opinion I don’t see this as a big advantage, because you bring new complexity (FCoE is different that IP). I think that storage, when possible, must be on a dedicated network (for security, performance, simplicity reasons).”

One year ago, I’ve described how to disable the certificate warning in the Windows View Client 5.0, by using GPO or a direct change in the local registry (on the client).

Now, with the new version 5.1 of the View Client there is a new way client side:

I’ve got a case of a host upgraded to VMware vSphere 5.1 with a determinist PSOD during each host reboot or shutdown (I’ve found the issue during the first patch update). No difference if hosts where rebuild from scratch with a similar configuration. And no difference with all recent ESXi patches.

After a full upgrade of each BIOS, firmware and drivers (and of course the HCL verification) I’ve only found the KB 2038281 (ESXi 5.1 host fails with a purple diagnostic screen when Beacon probing is enabled).

Syntoms where similar:

  • Cannot reboot a ESXi 5.1 host when Beacon probing is enabled.
  • Rebooting an ESXi 5.1 host enabled with Beacon probing on the NIC teaming policy fails with a purple diagnostic screen.

This is a known issue affecting ESXi 5.1.x and will fixed in a future update. To work around this issue, deactivate Beacon probing if it is activated on one of the switches.

Unfortunately was not my case (and is still open) but I suppose that is some behavior in the the new distributed virtual switches implementation, combined with the used NIC (Broadcom) that cause the issue (in fact, with standard virtual switches works perfect).

The available VCDX defense dates (and locations) are been recently announced on a thread in the VMware Community. Some were already well know (during the PEX event).

The interesting aspect is that is still possible reach the VCDX4(-DV) certification for the entire 2013 (big change on what was announced one year ago and really a good opportunity for VCDX candidates):

Candidates at all 2013 VCDX Defenses will be offered the opportunity to submit and defend vSphere4 and vSphere5-based designs in pursuit of the VCDX4 credential. Candidates may also choose to submit and defend vSphere5-based designs in pursuit of the VCDX-DV credential. Support for the VCDX4 credential will continue until the prerequisite certifications are retired.

There are different reason where you can you loose or corrupt your partition table of your VMFS volumes: resignature from another system (for example the backup server, if connected in SAN mode), a human mistake (datastore / delete), or maybe some storage issues.

In this case usually the VMFS partition is still there and also the related data: you have “only” to rebuild the right partition table. But this could really simple if you follow the recommended practice to have only one VMFS partition on each disk. In this case you have only to build the configuration for a single partition (with VMFS type) starting from the right offset (VMFS partitions are aligned) and ending on the latest block.

As written in the previous post, one common issue with recent servers of new generations is that maybe the NIC drivers are not included in the standard ESXi ISO.

An if you use the vendor (or a personal) customized ISO, could be possible that during a patch update or a version upgrade you loose the drivers and the system is no working anymore. In those cases you may have an ESXi that complete his bootstrap, but without any network connectivity is not usable and could be hard to fix the missing drivers because VUM and other remote tools tools could not work and, of course, also upload the right drivers could be hard.

If you have a new NIC card or a server of a new generation could be possible that the right driver is missing in the standard ESXi installation ISO. And without a working networking is not possible install the ESXi (the installation will stop because one requirement is at least a supported NIC).

Maybe the hardware vendor has a customized version of the ISO, but IMHO I don’t like this option (in some cases it could give some issues).

There could some cases where you may have some Windows (Server) completely isolated from the Internet, for example in some appliances or storage solution.

One interesting aspect that learn on Windows products during a DataCore training was that in this case you can have some delay in the user interface, both on the DataCore GUI, but also on the Windows one.
