Over the past few weeks, I've been messing around with 2.6.27.x based Xen guest kernels, and I'm pretty satisfied. These kernels use the new paravirt-ops interface, and will finally allow us to move away from the more-than-two-year-old 2.6.18 tree.

I'd appreciate some wider testing of these kernels -- available now under your configuration profile's kernel drop-down.

The sourceballs are also located here:

Thanks!

Just switched my dev linode over to this kernel. I'll let you know if I uncover any issues.

Installed and rebooted.

So far no problems. I will let you know how it does after a few days.

Do'h... fixed, thanks.

Ditto.

I'll try the new kernel at some point, but at the moment I want to see what kind of uptime I can achieve on my setup...

dfelicia@catch-22 ~ $ uname -a
Linux catch-22 2.6.27.4-linode14 #1 SMP Thu Nov 6 09:22:58 EST 2008 i686 Intel(R) Xeon(R) CPU L5420 @ 2.50GHz GenuineIntel GNU/Linux
dfelicia@catch-22 ~ $ uptime
 20:58:47 up 2 days, 11:52,  1 user,  load average: 0.12, 0.08, 0.01

So far so good. In fact, though it could quite possibly be due to some change/improvement by Internet provider, I swear access to my node is faster. When I ssh, I'm logged in instantly. My homepage also loads instantly (http://www.donsbox.com/). Previously, there was always a 1-2 second delay "waiting for donsbox.com..."

Any change from 2.8.18 -> 2.6.27 that could account for my now seemingly lower latency?

That's several years of kernel development... it could've been anything :)

Perhaps your use of a kernel from the future was affecting the space time continuum negatively thus increasing your latency.

MMMMM just started running it myself and I don't know if it's just a "Placebo" effect but my site feels a bit snappier also.

I'm running 32bit Gentoo with Drupal

I'll let you know if I see any adverse affects

OK, I made a typo. You guys are brutal

BTW, like marcus, I'm running 32-bit Gentoo.

Something interesting I've noticed, my CPU % has drastically dropped since switching to the new kernel

Two things I've noticed are that that bug in the CPU usage graphs were it was a perpetual ~3% is no longer there and I'm only seeing 2 CPU cores now instead of 4 as with 2.6.26.x.

Reboot and you'll see 4 cores again. This was a temporary misconfiguration on our end.
