Solution :
Step 1: Open connection from VI end from webclient or vSpear client, and launch the console of crashed VM.
Step 2: Power off and Power on the VM.
Step 3: During boot, interrupt the grub menu, and choose the kernel “Red Hat Enterprise Linux Server (2.6.32-504.8.1.el6.x86_64)”
The VM should be able to boot with this kernel
Step 4: Login as root
Step 5: Reinstall kernel-2.6.32-504.33.1.el6.x86_64, by executing the command
[root]# yum reinstall kernel-2.6.32-504.33.1.el6.x86_64 -y
Step 6: Reboot the VM
[root]# reboot
The VM should boot with the kernel, 2.6.32-504.33.1.el6.x86_64 without any manual intervention.
