I am trying to upgrade kernel on OnApp VM. Currently installed kernel is 2.6.32-279.22.1.el6.x86_64. The new version available is 2.6.32-504.16.2.el6.x86_64.
I installed new kernel 2.6.32-504.16.2.el6.x86_64 and rebooted the server, however the server is still booting with old kernel. No errors in /var/log/messages.
I rebooted the server by setting default kernel to 2.6.32-504.16.2.el6.x86_64 in grub console.
I have also heard this is a known issue with OnApp. Any ideas or suggestions?
