It has been a while since my last blog post and plenty of things have happened in the mean time. The biggest change for me is that I have left Perth, Western Australia and moved to Toronto, Canada.
But now for the reason of this post. Before I moved to Canada, I had set up a virtual machine running Centos 5.3 x64 so I can do development on my Macbook pro, but when i booted up the virtualbox image, I received this error:
Memory for crash kernel (0×0 to 0×0) notwithin permissible range
Kernel alive
kernel direct mapping tables up to 100000000 @ 8000-d000
Now according to the VirtualBox manual, you have to enable IO APIC if you want to run a 64-bit guest. But once I had enabled IO APIC, it would still not boot up and just displayed a whole list of errors. To get the virtual machine running, I modified the boot parameters and added: “noapic” to the end of the kernel arguments (without quotes) and the virtual machine was able to boot up. After Centos was booted up, I edited “/boot/grub/menu.lst” and added the noapic parameter to the kernel arguments so I didnt have to add the parameter every time I turn the virtaul machine on.
I hope this will help anyway who is having the same problem, as I know it has helped at least one person
