The VM network adapter is linked to the same physical network as the host system in this scenario. To use the VM network adapter as if it were a physical network adapter on the host machine, select the Bridged mode. Next, navigate to the network settings and pick the virtual network adapter's networking mode. It'll come in handy for applications that require 3D acceleration. Then, select Enable 3D acceleration from the drop-down menu (optional). Go to Display > Screen and set Video Memory to 128 MB. Select your recently created virtual machine and open the VM settings. It must be at least 20 GB in size.Īfter creating a new VM, some additional settings must be configured. The VM folder is intended for storing virtual disc files (such folder is selected by default). Hit Create to continue and configure a new virtual hard disk. Hard disk: Create a virtual hard disk now Note: Here I Have Given 4GB As Ram Size You Can Set As Per Your System Requirements.Īlthough you should allow enough unallocated memory to operate your host OS, the VM memory capacity must be large enough to run a guest OS. Note: You Can Enter Any Name You Want Here I Am Going With Default Name.

In today's blog post, we'll look at how to set up Kali Linux as a virtual machine in VirtualBox (VM). Virtual machines can be extremely useful in this case. At the same time, settings are not saved after a system reboot when using Kali Live DVD.
Kali can be used as a Live DVD or installed as a host operating system (OS) on a computer like any other Linux.However, using Kali as a general-purpose desktop operating system is not recommended. Kali Linux, formerly known as BackTrack Linux, comes with a number of network auditing tools and apps. ‘hacks’ we have used for the last 30 years on BIOS systems are either impossible or need serious fixes to work again in a UEFI world.Kali Linux is a Debian-based Linux system that was created for penetration testing and is particularly beneficial for security professionals and amateurs.

repeat 1&2 if a firmware update is done.įrom what I can tell, most of the install methods and 0 downtime See if a Dell firmware update set is available and if the changelogs say it fixes EFI boot issuesĤ.

Boot from EL7 iso and see if EFI variables/modules workģ. Boot from EL6 iso and see if EFI variables/modules workĢ. My debugging methodology at this point would be the following:ġ. It was ok with the same old model but a new one was not possible. I had this with one set of systems where the system required a hard flush of UEFI buffers before it would boot from a larger disk. The firmware can lock down what it thinks is ok to boot from and may require some sort of flush depending on the type of disks it thinks are ok. From all the other items you listed in the the thread, your system looks like it is booting into a form where it is saying it isn’t UEFI anymore which would be a boot firmware option. Did you mean that you are using the secure boot options? I don’t know if that ties down a system to a specific disk until it is cleared from the install. I tried to run efibootmgr, but it wants a model named efivars loaded, but there is no such module available. The machine boots and is using the new system disk (a raid array in degraded mode). I ended up putting the original /dev/sda in. Logic that wants the original disk, even if everything is moved over. It seems there is something in the UEFI (secure boot) Then I shut the machine down, swapped in the new backup disk and pulled the old system disk and installed the third new disk. Meanwhile I partitioned a second 2TB disk using a USB SATA dock and copied the old 500G /dev/sdc1 to the new 2TB disk. Then created a new RAID set (degraded) with /dev/sdb3, used pvcreate on it, used vgextend to add it to the system volume group, then used pvmove to move the extents from the old disk to the new disk.
dev/sdb2 to /dev/sda2 (boot raid set) and dd’ed /dev/sda1 to /dev/sdb1. Partitioned it (with parted) to be much like /dev/sda (except partition 3 is way bigger). This morning I shut the machine down and pulled /dev/sdb and installed a new 2TB disk as a new /dev/sdb. dev/sdc is a disk containing one file system and mostly used by AMANDA for backup (it has a “virtual” tape changer). dev/sda3 and /dev/sdb3 are a mirror raid (/dev/md1), with LVM on top of that. dev/sda2 and /dev/sdb2 are a mirror raid (/dev/md0) It is set up with /dev/sda and /dev/sdb with each three partitions:
The machine has 4 SATA ports, one used for the optical disk and three for the hard drives. OK, I wanted to replace the 500G disks in a Dell T20 server with new 2TBĭisks.
