We recently build a RHEL6 virtualization cluster. Using RedHat Cluster Suite, libvirt, and kvm. To manage our RHEL boxes, we use RHN Satellite. On our RHEL5 cluster, this works very well. We can provision VM's using satellite and kickstart. Enter some data, clickity-click, wait 15 minutes, and you have a VM. After building our fancy new cluster on RHEL6 however, we found this functionality broken. This blog entry is a loose transcription of the aggrivation that I've dealt with attempting to hammer out this issue with RedHat's support.
I work in IT, and not to sound vain, but I think I'm pretty damn good at it. I've worked on environments that I've built myself, inherited from others, or that I've been tossed into and expected to support. One thing I've never been is a consultant. At least not professionally.
I recently upgraded to Fedora 15, and I'm very put off by the selection of window managers, and their stability I'm a long time Gnome2 user. Gnome has a nice set of features, it works well, its stable, /cheer for the gnome team. Gnome3, which is included in Fedora 15, is horrid. Probably because it's still young. Gnome 3, with gnome shell does not work at all on my desktop at work because of how my displays are configured (4 displays, spanning 2 cards with xinerama, which kills 3d-support) and while it works, technically, on my laptop, it does NOT work reliabl
This write-up is incomplete, but it has some useful information about my first attempt at ganeti. I'll be attempting this install on another set of machines in the near future, and i'll post another blog entry.
I'm a system administrtor, I started out as a hacker, a tinkerer, and a curious sort. No, I've never stolen your credit card number from Bob's pet mart's web site, and i've never defaced whitehouse.gov. I'm using hacker in a more positive light. Something you'll find I'm adamant about.
I was doing some thinking this morning while on my hour long commute. Thinking about old times, and old friends. High school, when I was in high school, I went to a technical school, we had this project. A hand full of us were picked to physically wire the school for cat5. It wasn't a huge building, 5 of us were picked. Once the cable was laid, we brought on 5 more students, and we built or upgraded 170 pc's.
I'm just reading about this now, but apparently Yesterday, 4/22/2011, morning a network event took severely hindered Amazon's EC2 cloud. According to an article I found on Internetnews.com Amazon is blaming the outage on storage issues caused by a network event.
A report form amazon said:
VDI, or Virtual Desktop Infrastructure is one of those new IT buzzwords. VMWare does it, Citrix Xen Does it, a few others do it. RedHat does it (or, is in the process of doing it) as well.
