    Xen Kernel Question


    I use at the moment the following kernel inside a Centos5 VM in XEN:
    [email protected] [~]# uname -a
    Linux 2.6.18-194.32.1.el5xen #1 SMP Wed Jan 5 18:44:24 EST 2011 x86_64 x86_64 x86_64 GNU/Linux

    When I want to update this kernel, I just realized, that the kernel name does not contain the word xen anymore:

    [email protected] [~]# yum update kernel-xen
    Loaded plugins: fastestmirror
    Loading mirror speeds from cached hostfile

    Will this VM boot after a reboot, or do I need another kernel?

    The package version wont end in "xen" as the package name is kernel-xen.

    Once it's installed you will see vmlinuz-2.6.18-371.4.1.el5xen in /boot and when running the kernel you see in "uname -r" 2.6.18-371.4.1.el5xen

    once you update your kernel, check your GRUB configuration and make sure the default kernel selected is xen kernel Half Dedicated Half Price
