Kernel Panic when booting ubuntu 12.04 LTS in virtualbox

I try to run it in Virtualbox 4.3.6 but it says: Kernel panic : attempted to kill init! Can anyone help me???

Answer 1

Here are some things you could try:

1. Increase the Memory and Video Memory available to the VM
2. Download a fresh ISO using a torrent, that way you can guarantee it won't be corrupt. See http://www.ubuntu.com/download/alternative-downloads
3. Delete the VM and create a fresh one with the default options.
4. Try disabling the USB Controller, the Network Adapter, and the Audio to see if that helps.
5. Look at options like VT-X/AMD-V, Nested Paging, PAE/NX and IO APIC and the Chipset. Switching some of these may sometimes help.
