The first VMUG IT User Conference has been finally announced!

A User Conference is not your regular VMUG meeting, it’s a full blown conference, with separate tracks and prominent guest speakers (there will be some interesting announce about them!). A good opportunity to learn more, share experiences, and make networking.

And note that some session will also be in english, so this is not only for Italian people, but for all VMUG members!

VMware Partner Exchange is a big event, like VMworld, but dedicated to the VMware partners (like the international Microsoft WPC or other similar events). This year will be held at Las Vegas from 25 to 28 February.

In a View environment the PCoIP is usually the right choice and on a LAN works really well (see also the previous post about PCoIP and RDP differences). But on a wide-area networks (WANs)you have to consider some aspects to have a reasonable reactivity or to maximize the number of remote clients: you must consider bandwidth constraints and latency issues. The PCoIP display protocol provided by VMware adapts to varying latency and bandwidth conditions, but some optimization may be needed.

In a VMware View environment usually PCoIP protocol is preferred to the RDP one due to several reasons. I don’t want to spend too much time about the latency, throughput, reactivity, user experience different between those two protocols… in most cases PCoIP is better compared to RDP.

But PCoIP protocol has some limits that your have to consider in your design and mainly are described in the View Architecture Planning guide.

Actually Windows 8 is not (officiall) 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 (for more information see the previous post).

But in order to use Windows 8 as a virtual desktop it is more complicated. First you must run Windows 8 on vSphere (and this is really simple with vSphere 5.1 where both Windows 8 and Windows Server 2012 are supported as a guests). Just remember to enable the 3D support in the video card (virtual hardware 8 is required).

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.
