Yep, I'm a big OpenVZ guy. OpenVZ 7 just came out at the end of July. It added KVM virtual machines in addition to OpenVZ containers. That was a big change considering the commercial product OpenVZ came from (PCS - Parallels Cloud Server v6) used a proprietary hypervisor. Den Lunev, who has worked on this stuff for 15+ years (SWsoft, Parallels, and now Virtuozzo) spoke about everything that went into moving to KVM in Virtuozzo 7 / OpenVZ 7 at the KVM Forum last week. Enjoy! (PDF Slide Deck)
KVM Forum was held at LinuxCon last week. The slides have appeared and the videos are starting to appear. So far they have posted the three keynotes that are status reports on KVM, QEMU and libvirt. Here's the status report for KVM. Enjoy!
Just released today... Red Hat's Josh Bressers talks about various security topics... yes, from Red Hat Summit 2016. Enjoy!
RHEL has been around for 14 years. A lot has changed in that time. Red Hat's Gunnar Hellekson (Director, Product Management) tries to explain issues and solutions for coming RHEL releases. From Red Hat Summit 2016. Enjoy!
On July 5th, 2016 Michael Biebl spoke at DebConf16 on systemd in Debian. This was an update to the talk last year. Enjoy!
As you may know, I've been remixing Fedora for several years for my own personal use... called MontanaLinux. I've also been remixing CentOS and Scientific Linux and thought I'd write a little bit about it.
The main reason I created the EL7 remixes is because I have a few older HP Proliant servers at work that have the CCISS Raid Controller and Red Hat dropped support for those in RHEL 7. Also, I originally included both GNOME and KDE as part of it but have since decided to make it leaner by switching to XFCE 4.12 that is available in EPEL... and of course it includes all of the available updates as of build time.
I make two flavors:
- Minimal - Just the basic XFCE with no desktop applications. This is pretty close to the CentOS minimal install except with X11 and bare bones XFCE. It weights in under 550MB.
- Full - XFCE with Firefox, LibreOffice, GIMP, Inkscape and a handful of useful tools like gParted, nwipe, rdiff-backup, etc. This weights in under 900MB.
Here are two short screencasts in webm (vp9/opus) format. The first shows the minimal install and the second one shows the full. While I'm not trying to provide a primer of the Anaconda installer, I do rush through it both times and show you post install first boot.

MontanaLinux-CentOS-7-Full-20160617.webm (5 minutes, 4.4 MB)
If anyone is interested in downloading my remix or building it themselves just email me and I'll be happy to provide the needed details. Luckily livecd-tools with livecd-creator makes it not only possible to make your own spin / remix... but fairly easy if you aren't scared of some command line. Enjoy!
Deb Nicholson talked about the state of software patents after the United States Supreme Court's ruling in the landmark Alice vs. CLS Bank case. Enjoy!
Rob Potter brought the following video to my attention when he posted a link on the BozemanLUG mailing list. I converted the original .mp4 to a .webm. Enjoy.
Just got back from LFNW this morning. Gary, Rob and I went. This year they were able to capture screencasts from all of the presentations. Here's one I enjoyed attending:
Gallatin County had an "IT Surplus Sale" today. I picked up a Dell PowerEdge R710 2U server for only $50. It is a complete, functional system except they removed the hard drives... so I'm going to have to buy some. A new 4TB 2.5" Seagate Constellation ES SAS 7200RPM will set me back about $180.
18 DIMM sockets, 6 populated with 2GB (12GB installed, 288GB max)
8 2.5" hard drive bays - empty, first two have to be SAS drives, others can be SAS or SATA
Perc 6 / LSI Logic / Symbios Logic MegaRAID SAS 2108 RAID card
2 quad-core Intel Xeon E5620 @ 2.40GHz (combined BogoMIPS 76803.42)
6 GBit ethernet ports (4 onboard, 2 on a descreet card)
2 Riser cards with 2 empty slots
Dual power supplies
With only 12GB of RAM, maybe I need to buy some more RAM. Here's how much the various sizes of DDR3 1600 ECC DIMMs cost:
4GB DIMM - $48, 8GB DIMM - $65, 16GB DIMM - $118
Not too bad for $50, eh? They even threw in a Dell PowerEdge 2950 2U server for free with it.
