Open Synaptic and look for a different kernel.

Yes!!

You can get anything you want here:
http://kernel.org

If you tell us more about you system and what you want to accomplish, then you'll get better help.......

Intalling a kernel from kernel.org isn't the easiest of tasks if you're new to Linux. It's probably easier and less error-prone if you use the package manager that comes with your distro. What distro are you running?

Also, most distro's will keep one or two older kernels installed when the kernel is updated. You should be able to select those from the grub menu on boot.

hi...

i am having a guest VM in Xen whose kernel information is as follow:
# uname -r
2.6.32-71.el6.i686

But my requirement is to change it to-
# uname -r
2.6.32.12-0.7.1.xs6.0.0.529.170661xen

The distro information is
LSB Version: :core-4.0-ia32:core-4.0-noarch:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-ia32:printing-4.0-noarch
Distributor ID: CentOS
Description: CentOS Linux release 6.0 (Final)
Release: 6.0
Codename: Final

I'm no expert on CentOS, but if it's not installed already (check the Grub boot menu on start-up), you should be able to install any kernel from yum.

Then add an entry for this kernel to your Grub configuration.

it says: No package kernel-2.6.32.12-0.7.1.xs6.0.0.529.170661xen available.
