Memory for crash kernel (0x0 to 0x0) notwithin permissible range

Every time I boot my VM, I see this message. I am using Oracle Linux 5.4.




This is explained in Redhat bugzilla bug# 431584

https://bugzilla.redhat.com/show_bug.cgi?id=431584

And that bug is closed as "NOT A BUG".

From the bug text I understand that this is informative (probably wrong way) message that memory is not allocated to kdump.

I remember I had NOT selected "Enable kdump" check box during installation.

So I decided to enable kdump to get rid of this message which only causes confusion but in real there is no problem with the OS/Hardware.

Enable KDUMP:

Rebooted the VM and now I don't see that message anymore.

HTH.
