Are you caught with a irritating “kernel panic NOAPIC” error throughout your Metasploitable boot in VirtualBox? Don’t fear—this information will aid you troubleshoot and repair the difficulty utilizing the “noapic” possibility. We’ll additionally delve into related ideas like ACPI, GRUB, and kernel boot choices for a deeper understanding.

Legacy GRUB, or GRUB 0.97, as soon as served because the bootloader of alternative for quite a few Linux distributions, paving the best way for the choice and booting of working programs on a pc. Metasploit 2, the predecessor of the now-renowned penetration testing framework, relied on Legacy GRUB as well its digital machine (VM) pictures effectively.
About VirtualBox: A Virtualization Platform
Oracle’s VirtualBox is a number one open-source virtualization platform that enables for the simultaneous operation of a number of working programs on a single {hardware} base. Its capabilities prolong to the creation, administration, and execution of digital machines, offering an optimum testing floor for penetration testing instruments like Metasploit.
About ACPI and NoAPIC Kernel Boot Choices
The Superior Configuration and Energy Interface (ACPI) is an industry-standard for environment friendly energy administration throughout fashionable computing units. It encompasses {hardware} gadget configuration, energy state administration, and interrupt dealing with. The NoAPIC kernel boot possibility turns into important in sure conditions, significantly when addressing older {hardware} or compatibility points, by disabling the Superior Programmable Interrupt Controller (APIC), which manages interrupt requests (IRQs) in a system.
Kernel Panics: Causes and Options
A kernel panic represents a crucial system error detected by the Linux kernel that hampers continued operation as a result of an irrecoverable error or inconsistency. Such a state might result in a system freeze, an surprising reboot, or the show of a panic message.
Let’s Get Began
Booting Into NOAPIC Mode Throughout GRUB Booting
Non permanent Change for Testing
- Restart Your Digital Machine: Start by restarting your Metasploitable digital machine in VirtualBox.
- Entry GRUB Menu: As quickly because the VM begins booting, press and maintain the Shift key to convey up the GRUB menu. If Shift doesn’t work, strive tapping the Esc key as a substitute.
- Edit Boot Choices: Use the arrow keys to navigate to the default boot entry (normally the primary). Press e to edit the boot parameters.
- Modify Kernel Boot Parameters: Search for the road beginning with linux or kernel. Navigate to the top of this line and add noapic (observe the area earlier than noapic). This modification tells the kernel as well with out utilizing the APIC.
- Boot with Modified Parameters: Press Ctrl + X or F10 (relying in your GRUB model) as well with the modified parameters. This boot will apply the noapic possibility with out completely altering your configuration.
Making a Everlasting GRUB Boot Change
Everlasting Answer
- Open a Terminal: When you’ve booted into your system utilizing the short-term methodology and verified that noapic resolves your difficulty, open a terminal window out of your desktop utility menu.
- Edit the GRUB Configuration File: Use your most popular textual content editor with superuser privileges to change the GRUB configuration. For GRUB 0.97 (Legacy GRUB), the file is
/boot/grub/menu.lst
.
sudo nano /boot/grub/menu.lst
Discover the Kernel Line: Within the menu.lst file, find the part with kernel choices, normally starting with the title of your OS.
Add the noapic Parameter Completely: Append noapic
to the kernel line to make sure the parameter is utilized at each boot:
kernel /boot/vmlinuz- root=/dev/sda1 ro quiet splash noapic
Save and Exit: Affirm your modifications and shut the editor. This motion completely alters your boot parameters.
Replace GRUB (if required): Some Linux distributions require updating GRUB for modifications to take impact. This won’t be needed for Legacy GRUB, however it’s good follow to verify your distribution’s documentation.
Reboot: Restart your system to make sure the modifications are utilized efficiently. Your system ought to now boot with noapic
by default, circumventing the kernel panic difficulty.
Wrapping Up
Modifying the “/boot/grub/menu.lst” file to incorporate the noapic parameter is a dependable workaround for resolving kernel panic errors throughout the Metasploitable boot course of in VirtualBox. This adjustment ensures smoother operation by addressing interrupt dealing with points that might result in system halts. Contemplate diving into the wealthy documentation and group boards devoted to VirtualBox and Metasploit for additional exploration and troubleshooting.
