A couple of days there have been some reports that Red Hat will release a commercialized version of deltacloud, an abstraction layer for different kinds of virtualization technologies and clouds such as VMware, RHEV, Amazon EC2 etc. Red Hat puts a lot of resources on virtualization, they maintain and/or sponsor multiple projects in parallel. The most important from my point of view is libvirt which is as well an abstraction layer for different virtulization technologies such as VMware, KVM, Xen ….Read More

KVM supports live migration between CPUs with different features
The video is a bit old, it is from November 2008. But it is still quite interesting to see and discuss about it. With KVM you can upgrade your farm of servers easy, it does not matter if the new servers have CPUs with new features or not. I’m not sure if you can do this with ESX, I guess not, you probably need to migrate them shut down. httpvh://www.youtube.com/watch?v=EuhU6jJjpAQ Have fun!
A brief test of RHEL 6 Beta 1

It seems to get even more interesting ….Read More
Kernel questions about RHEL6, ESX support and experiences with F13a3
Still no official informations Red Hat is still refusing any questions about the features of RHEL 6 and its Linux Kernel. However: Since Vanilla Kernel 2.6.33 vmxnet3 and pvscsi is supported. Fedora 13 Alpha 3 is shipped with a derivate of Kernel 2.6.33. I still hope that Red Hat is switching to 2.6.33 or back-porting the VMWare code to its 2.6.32 derivative Kernel as known by RHEL 6 Alpha 3. Experiences with F13a3 so far Installing F13a3 on a ESX ….Read More

On the Red Hat Summit 2009, there was a presentation held by Tim Burke which gives just some hints that RHEL6 is actually approaching, ….Read More
