The reason behind it is not because of the lack of news in the virtualization business, but rather a lack of time, interest and opportunity to play around with virtualization software.

I’m currently in the process of moving, my lab is dismantled and I have no spare time available for playing around with virtualization. So, sorry, no updates for a while… Hopefully, things will change when I am settled in the new place and have figured out what my new job is all about :)

Performance monitoring problem

Categories:

performance-monitoring

My new R710 running ESXi 4.0 has one problem: When the CPU load comes close to maximum, all performance monitoring for the host failes. Only a few, random monitoring requests comes through, making the resource graphs in vCenter look pretty ugly.

According to The Register, Oracle is going to kill Virtual Iron fron the end of June 2009. Now, I’m not that surprised, there are a lot of Xen based virtualization products on the market. The only difference between them is the management software.

Clever solutions: Microsoft Azure and its fabric controller

Categories:

I’m not the biggest fan of Microsoft Hyper-V which I assume is the hypervisor used in their Azure solution. As illustrated earlier, Hyper-V has its problems, especially with live migration and iSCSI support. But, the Azure have some clever solution on its own.
