"The session was disconnected.  If you want to continue, try to connect again.  If the problem persists, contact your system administrator. 

Would you like to reconnect?"

VMTurbo, a unique way to better control your virtualized environments

[fa icon="pencil'] Posted by Scott Pelletier [fa icon="calendar'] January 12, 2015 [fa icon="tags'] VMware, Microsoft Hyper-V

Been trying out this VMTurbo stuff and it's definitely a unique approach versus traditional systems management. It's more actionable and automated versus telling me a bunch of information that I would have to decipher and deal with. Both approaches have merit but it depends on how you'd like to control your virtualization environment that makes the difference. Give it a try and let me know your thoughts.

Recently I upgraded to Windows 8 on my Lenovo W510 in order to setup a virtual lab in Hyper-V. Hoping to save others the frustration I experienced during BIOS configuration, I thought I'd share the Intel hardware virtualization settings necessary for the role. The order that settings are made and complete power downs after certain settings changes are significant. Don't save time with warm boots!

Cisco AnyConnect vs. Internet Connection Sharing in Windows 8

[fa icon="pencil'] Posted by Dan Martin [fa icon="calendar'] June 2, 2013 [fa icon="tags'] Virtualization, Microsoft Hyper-V, Cisco

Having recently installed Windows 8 on my laptop to take advantage of the Client Hyper-V, I'm working through the kinks that come with a new OS on my daily driver.
