Hi,
I started with a CentOS 5.2 linode, I always used the 2.6.18 latest from linode, now after yum updating to CentOS 5.6 I switched from 2.6.18 to the Latest 2.6 Paravirt (2.6.38-x86_64-linode17).

It seems that it works fine, is there something that I need to know in particular after this switch?
Is a reboot all I need to do to use this new kernel on my CentOS 5.6?

The paravirt kernels do not have access to the host machine's hardware clock, only a virtual one, so it tends to drift. Make sure you setup ntp



Yes.

Thanks for the reply, I just used NTP with previous kernel so its ok but now I'm getting this error hourly:

/etc/cron.hourly/mcelog.cron:

mcelog: Cannot find SMBIOS DMI tables

mcelog.cron isn't from CentOS - have you installed something from extra repositories?

Anyway, MCE are "machine check exceptions"; they're hardware errors reporting to the kernel. Given you don't have direct access to the hardware you might as well remove whatever package you installed.
