Somebody has it running already? or do we have to wait till ASL is compatible?

There should be no problems, but I haven't had the time to try it yet.

Works just fine on the one machine I tested it on just now.

You might want to read the release notes and release announcement before upgrading, as there are some known issues. Most notably the performance issue with 3ware RAID cards. CentOS has an alternative kernel in testing and I expect Red Hat to release an update for this soon.

Also don't forget to use 'yum upgrade' instead of 'yum update' when installing a new OS upgrade.

There was one warning from the new selinux-policy-targeted package:
qscand homedir /var/spool/qscan or its parent directory conflicts with a defined context in /etc/selinux/targeted/contexts/files/file_contexts, /usr/sbin/genhomedircon will not create a new context. This usually indicates an incorrectly defined system account. If it is a system account please make sure its login shell is /sbin/nologin.
We don't use SELinux on our servers (ASL even disables it for the ASL kernel), but I don't know if would be a problem when you do use SELinux.

What about this: http://kb.parallels.com/en/234

Has anyone did this or just yum upgrade without editing yum.conf?

I don't use those instructions.

sendmail, bind-chroot and caching-nameserver should not be installed on your server and they won't spontaneously be installed when running yum upgrade or yum update. You could add them to the exclude list to be sure though, it doesn't hurt either.

I recommend not putting kernel* in the exclude list. Kernel upgrades are important, there was a local root exploit not too long ago that affected a lot of machines.

It´s a virtual maschine (VE) not a hardware-root-maschine.
Does it matter?

If it's Virtuozzo/OpenVZ then your server uses the kernel of the host machine and then you cannot control the kernel yourself. In that case you probably don't even have a kernel package installed in your virtual server, so it doesn't really matter.

I updated two ASL2 machines without problems (yet) :)

I guess this is not the case for the ART kernels? I have one server with a 3Ware RAID controller...

No, that is just an issue with the current RHEL/CentOS 5.2 kernel.
