[Cialug] Meeting next week.

[Matt Breitbach]

CentOS still supports Xen out of the box, and it's quite popular with the
hosting market from what I can tell.  Also, the recently announced OpenStack
framework is based on Xen.  I doubt that Xen will be going by the wayside
soon.

The defacto topic next week is virtualizatiion.

Do folks care about this?  (Seems to mostly be VirtualBox and VMware these
days, are Xen and KVM dead?)


I can speak with confidence that KVM is not dead. It is definitely eating
into Xen's territory. VirtualBox is primarily for desktop/workstation
virtualization while KVM (thanks to libvirt and such) works great on
headless or remote machines. 

I don't know about Xen - it used to provide a very interesting nitch
(paravirtualization) which is, as far as I can tell, at the low end of the
spectrum these days. I think it's losing ground at that end to openvz and
the like because they (openvz, etc) are more friendly/profitable to
commercial ISPs. OpenVZ allows ISPs to oversell their capacity. It's not
technically virtualization though. 

It's tricky to find a modern distro that supports Xen out of the box. Debian
does but with an ancient kernel. Ubuntu and RH both dropped it in favor of
kvm. I thought if I went to their website I'd see info on this but didn't
find it. Amazon's EC2 service is all built around Xen though, so there is
something there.
