That means I'm looking forward to CentOS 6 soon. I hope.

QEMU/KVM virtualization is very nice and hopefully I won't need to rely on bleeding edge (though surprisingly stable) Fedora 13+ for a good stock deployment from now on.

CentOS people are saying 4-6 weeks.

epo• 16 years ago

Nice, something to do over Christmas as I am teetotal this year.

They are already at it: https://twitter.com/#!/CentOS/status/2673891377946624

I hope the standard version of Python is upgraded beyond 2.4.X.

forkqueue• 16 years ago

Python 2.6. Also PHP 5.3 and MySQL 5.1.

avar• 16 years ago

But only Perl 5.10.1, they didn't upgrade to 5.12.* for some reason.

This is fantastic news for virtualization:

1. Memory deduplication on kvm machines: matching memory pages are COWed. Hopefully there is a re-spin of the virtio drivers too (which rock, btw).

2. Way newer kvm/libvirt (the old ones sucked)

3. Python 2.6. They skipped 2.5 entirely, which is nice.

Just keep in mind, they'll be supporting it for a VERY long time, so RHEL6 will be looking pretty tired in another 3.5 years (the current age of RHEL5).

is memory deduplication the KSM thingy released about a year ago?

rwmj3• 16 years ago

Yes. In fact KSM can be used on any Linux process although you have to mark the regions that can be merged with a special mmap flag. It works well with VMs because they basically mmap a huge chunk of sequential memory (for the VM's RAM) which is marked thus.

Edit: madvise, not mmap.

amitshah• 16 years ago

Yes.

libguestfs ... a proper way to access and edit disk images.

scalyweb• 16 years ago

Thanks for creating and putting so many hours into this library. I think this tool more than any other has allowed me to do so much with KVM.

ciupicri2• 16 years ago

It's too bad they didn't skip to Python 2.7 which seems that will be the last 2.x version [1].

I don't think 2.7 has been out nearly long enough for a Linux distro to be based on it. RHEL uses Python for core stuff like yum.

I wonder, will I be able to use Xen on RHEL6 servers? Should I?

I'm learning to use virtualization and I picked Xen because seemed to me like solid technology - it's good for Amazon, Google and prgmr.com, so surely it will be good enough for me? On the other hand, it is not included in the kernel, its usage tends to lead to using anscient kernels, Red Hat and Ubuntu are moving away from it. I'm in doubt what virtualization technology should I be using.

skorgu• 16 years ago

The pv_ops patches are just starting to make it into mainline now, KVM's had quite a head start.

wmf2• 16 years ago

Xen is dead. KVM is now equally "solid", easier to use, better supported, etc.

blantonl• 16 years ago

This truly is a milestone release for Red Hat that is putting a stake in the industry as the foundation for the next decade.

Am I the only one that took a double-take at that sentence?

seiji• 16 years ago

I was fond of: This is a milestone event for Red Hat as we once again push forward and upward our leadership position in the market.

The message seems to have manifested from the collective will of all redhat employees. There's no human signer or sender.

Does anyone know if they removed all the X11 dependency garbage for a server install? An RHEL5 was approaching the bloat of a Solaris install. There was no "click here to install a slim server" option.

freiheit2• 16 years ago

From some investigation, I think the simple answer is "yes", as long as you leave out devel, java, and a few specific tools. And totally yes for all the Xserver stuff.

I've got a kickstarted system with "@additional-server-devel @base, @compat-libraries, @core, @development, @network-tools, @performance, @server-platform-devel, @system-admin-tools" package groups and a few specific package tweaks. Fits in under 2GB. Looks like there's no X server stuff, but there's libX11, a few other libX* packages, and gtk2 installed... It's being pulled in by some of the java stuff, seekwatcher, latencytop, python-matplotlib and a couple other devel things I probably don't care about. There's only 29 packages it wants to remove if I tell yum to remove libX11-common.

Looks to me like with a few more tweaks to my kickstart I'll be able to get all the X11 deps out.

foobarbazetc• 16 years ago

PostgreSQL 9.0 would have been nice, but I guess that's understandable.

Otherwise, a great release. RHEL is awesome. :)
