The curious case of the not connecting WiFi adapter to a public hotspot in Windows 10

So I had this issue previously, with another Dell laptop and a Killer WiFi adapter, and I didn’t take the effort to create this blog (sometimes I write a blog, just to remember a specific issue in a couple years from now) a while ago. Unfortunately, I completely forget the solution (it kicked in after an hour or so)…

The issue

You cannot connect to a public hotspot, well you can connect but the redirection page takes ages to load, you get some information displayed on the page. But you are stuck in the process of paying or accepting the legal notice before using the Internet.

Managing Hyper-V 2012 R2 core server remotely in a Workgroup environment.

Win2012R2_Logo Recently I was recreating my lab environment. At first I used Citrix XenServer on my lab server, a HP DL380, but now I want move to Windows 2012 R2 Hyper-V. I want to make the best use of the available hardware resources, and I like working on the command line and PowerShell, so I’ve installed Windows 2012 R2 Core. After the installation is finished you are presented with nothing but a small black command line box. image

  To help you with the basic configuration of your Windows 2012 R2 Core installation Microsoft provides a small toolkit to get you up on your feet and running. This tool is called sconfig. This tool will let you perform some basic server configuration tasks.image Read more

Citrix: Import NetScaler (10.1 Build 120.13) on Hyper-V Server 2012R2 / 8.1

Hyper-V did not find virtual machines to import from locationI tried importing a Citrix NetScaler Virtual Appliance on a Windows 8.1 machine and received the error “Hyper-V did not find virtual machines to import from location”. Importing the same appliance on Windows Server 2012 did work.

The cause of this error is that the virtual machine is exported from a Windows Server 2008R2 server (running Hyper-V 2) and Microsoft deprecated the WMI root\virtualization namespace v1 in Windows Server 2012 (Hyper-V 3) and removed it Windows Server 2012 R2 (see TechNet).  There’s no support for the old WMI format.

The curious case of the non responsive Windows 2012 Hyper-V server

Author: Daniel Nikolic

Suddenly the System Center Virtual Machine Manager (SCVMM) 2012 Service Pack 1 CTP 2 version could not connect to the Windows 2012 Hyper-V server, different error messages appeared which didn’t really make sense:

Error (2916)
VMM is unable to complete the request. The connection to the agent %MACHINENAME% was lost.
Unknown error (0x80338126)

Recommended Action
Ensure that the WS-Management service and the agent are installed and running and that a firewall is not blocking HTTPS traffic.

This problem can also be caused by WMI service crash. Ensure that KB 982293 (http://support.microsoft.com/kb/982293) is installed on the machine if it is running Windows Server 2008 R2.

If the error persists, reboot %MACHINENAME% and then try the operation again.

Live P2V for Hyper-V

When you want to do a P2V ( physical to virtual ) migration Microsoft expect you to have a or build a management environment for it. This is great because you can monitor the environment before you turn it in to a virtual one.This is when time is on your site. In the picture below you see the Microsoft possibilities for migrating to a virtual environment

Hyper-V (offline) patch management is catching up.

VMware orientated people know the VMware update manager. With this tool/plug-in in vCenter you can automate patch management of VMware ESX hosts and virtual machines which eliminate manual tracking and patching. This also works for offline virtual machines. For Hyper-v Microsoft got the Virtual Machine Servicing Tool (VMST) which works in combination with WSUS or SCCM to get the same result.

A read a article of the VMST 3.0 version of the tool. This version is still in beta so maybe some futures will disappear in the final version. The current version 2.1 this tested guidance and automated tools let you service offline virtual machines in your SCVMM library. The new, still in beta, 3.0 version adds some powerful functions. Functions that already exist on a VMware platform. Then new functions are designed to streamline the process of keeping your offline virtual machines, templates and VHDs up-to-date with the latest operating system and application updates.  VMST 3.0 helps you manage updating your offline virtual machines according to their needs. When using VMST 3.0, you can live migrate the virtual machines within a cluster to another host so the there may be maintenance on the physical host. All this can be done automatically. The only think i am missing is the opportunity to make a snapshot before patching a virtual machine. Maybe i missed that with ready the articles . VMware has the same opportunities (and more) for some time now and is at version 4.0 update 1 patch 1.

For a VMware administrator with some history I though how did we accomplished that without update manager? It is great to see opponents trying to catch-up. I am curious what will be the answer of VMware, what more do we want form a update manager?

Hyper-V calculator

Although I am a VMware oriented I follow some blogs (RRS feeds) that have Microsoft (read Hyper-V) in their vision. It is nice to know what other virtualization suppliers are doing and you never know when you might need de knowledge to make a right decision. One of the Blogs I follow is the blog of Aidan Finn. He published a Hyper-V Calculator that’s covers RAM, disk, clustering and CPU. This can be used as a rule of thumb. Download the calculator here
