Speaking engagements

It’s a spring, and it’s a season of conferences . These days I’m quite busy with trips and presentations. After giving a presentation about Dynamic memory last week at the Microsoft Network conference in Banja Luka, Bosnia and Herzegovina, tomorrow I will travel to Mostar, Bosnia and Herzegovina to give the same presentation again, at [...]

Always read prerequisites

Always read prerequisites. Period. I will be speaking at the Microsoft Network conference in Bosnia and Herzegovina this Thursday about Dynamic memory. I already spoke twice about DM, and I have a slide explaining prerequisites for the guest operating system, among which are the Enterprise or Ultimate version of Vista/Windows7. I know that, and I [...]

Windows Server 2008 R2 SP1 is RTM!

After a couple of months of intensive testing, Microsoft finally announced SP1 for Windows Server 2008 R2 RTM! I already wrote a couple of posts about Dynamic memory, it’s architecture and a need for it, and I also gave two presentations about it. I tested it for a couple of times, and it proved to [...]

Dynamic Memory Architecture

Have you ever start thinking about how it’s possible to have something like Dynamic Memory? For me, it was a “shock” to see memory available to virtual machine goes up and down constantly. I was wondering how something like that is possible, and here is a basic description of the process. First of all, it [...]

Why Dynamic Memory?

Memory is the key factor to the number of running virtual machines. In 99% cases, you will run out of your memory and won’t be able to start a new virtual machine. In 1% cases, you will have no more disk space  (that happens to me from time to time ). Virtualization helps your organization [...]

How to reserve a memory for a Hyper-V host?

With Windows Server 2008 R2 SP1 getting ready to RTM, system administrators should pay attention to one more thing. Hyper-V Dynamic Memory, the biggest feature in Windows Server 2008 R2 SP1, enables system administrators to oversubscribe (not overcommit) their RAM. It works great, but you could face some problems with a Hyper-V host.

Some info about Dynamic Memory

I’m sure many of you already know that Dynamic Memory feature will be added into Windows Server 2008 R2 SP1. With this feature, it will be possible for administrators to provide a range of RAM to a virtual machine. Hyper-V will then dynamically provide RAM to a virtual machine, based on virtual machine needs. This [...]
