One of my aims for this talk was to introduce people to the concepts behind virtualization and containers, explain that these aren’t really new technologies, and why there’s so much interest in them of late.
I also think there’s a lot of misinformation spread around these topics, so this was also an attempt to set some facts straight.
The slides are here, and I will post an update with the link to the video.
The talk introduced the KVM stack (Linux, KVM, QEMU, libvirt) and live migration; introduced ways the higher layers (especially oVirt and OpenStack) use KVM and migration, and what challenges the KVM team faces in working with varying use-cases and new features added to make migration work, and work faster.
There was a video recording, I will post the link to it in a separate post.
The talk introduced the KVM stack (Linux, KVM, QEMU, libvirt); briefly went over some features and the communities around the projects, and discussed some of the new features added to the KVM stack in the last year.
Next up is my talk on live migration of VMs at FOSDEM in Belgium.
QEMU is the software that creates virtual hardware which guest operating systems run on top of. All (well, almost all — see note below[*]) the hardware that a guest OS has access to is actually written to some specifications in software — i.e. no physical hardware is involved. For the QEMU/KVM hypervisor, most of these devices are written in the QEMU source repository. A few devices are part of the KVM code in the Linux kernel. QEMU also handles a lot of host-specific stuff, like storage and networking for the virtual machines.
[* Exception: physical hardware devices assigned to guests.]
Many contributors to the QEMU and KVM projects meet at the annual KVM Forum conference to talk about new features, new developments, what changed since the last conference, etc.
The QEMU project released version 2.4 just a week before the 2015 edition of KVM Forum. I thought that was a good opportunity to gather a few developers and maintainers, and get them on video where we can see them speak about the improvements they made in the 2.4 release, and what we can expect in the 2.5 release.
In its 8th edition, the KVM Forum is moving back to North America this year, co-located with LinuxCon NA in Seattle. It starts with a KVM + Xen hackathon and the (invite-only) QEMU Summit on the 18th August, followed by talks and BOFs on the 19th, 20th, and the 21st. The schedule is here. To add all talks to your calendar, use this ics. The KVM Forum wiki page will have information on live streaming of talks, videos, slides, etc.
If you’re going to be around, please come up and say hi!
Yesterday was the first day at devconf.cz 2015. It’s my first devconf.cz, and I’m impressed by the large turnout and the perfect management of the event by the organizers.
Yesterday was also the day I presented my talk on live migration of QEMU/KVM VMs. The slides are here. There was also live video broadcast; and the recording is at this link. You’ll have to select the E104 section to view my talk. Also, that selection process needs flash. Unfortunate. I’ll check if there’s a direct link to my part of the talk.
Update: The direct link to the talk is here, thanks Donovan.
Mark your calendars for Jun 26 – 28 for FUDCon Pune. Start making travel arrangements. Think of topics to speak on, workshops and hackfests to organise, and have fun with friends.
FUDCon Pune is being hosted at MIT COE. They have excellent infrastructure and an amazing team of people who have been really helpful in addressing our needs to host a large conference.
Hop on to #fedora-india on freenode and the mailing list for information on volunteering. The etherpad has all the to-do items, feel free to jump in and help! The Twitter, Google+ and Facebook pages will have announcements and Planet Fedora will have blog posts from various people involved with the FUDCon.
It’s going to be a blast organising a FUDCon again!
