How to safely upgrade my kernel for a CentOS 5.6 XEN VPS, i want to make use of iotop and need to upgrade my kernel.

ps. yum upgrade kernel doesnt find any updates.
 
If your hosting provider does not have any instructions on how to upgrade kernel, then you should follow a How-To provided by a vendor of your OS or its community.

So do a full backup if it's possible with a VPS panel provided by your hoster, and run

Code: 
yum update

Read the output, and confirm with "Y".

You might need to read some How-To or manuals on the subject, because kernel upgrade has nothing with directadmin.
 
I already executed yum update but it did not work for me... I updated it via rpm and that worked (it is listed in grub.conf). So now i can see a newer kernel in /boot/grub/grub.conf that supports iotop.

Code: 
#cat /boot/grub/grub.conf
default=4
timeout=10

How can i fix grub? I don't know anything about grub, never ever used it before and i don't wanna make changes or break a critical part of the OS.
 
You should read docs, How-To and manuals to learn things about system administrating and Kernel Updating, including GRUB. These subjects are mostly offtopic for these forums.

Of course you might want to hire somebody to get a commerce service, or you might want to ask an assistance from your VPS provider (it seems you've got unmanaged VPS with the hosting package).

Maybe somebody else would want to help you for free, you can wait. Or get your server updated in a short time.
 
If someone want to help me for money contact me :)
