Linux Virtual Disk

2 months ago

by Syl21 in computer

Hello,

Today to prepare for a future article on LVM (Logical Volume Manager) a very powerful disk manager.

I will teach you how to mount a file and show you how create a virtual block device.

for more information on the commands that I run do not hesitate to "man command" and that "q" to exit the Doc

Example 1 - create an empty file, format it and then mount it:

  dd if = / dev / zero of = 1G bs = Disque_Virtuel.dd count = 1
 mkfs.ext4-F Disque_Virtuel.dd
 sudo mkdir / media / Disque_Virtuel
 sudo mount-o loop Disque_Virtuel.dd / media / Disque_Virtuel /
 ls / media / Disque_Virtuel /
 df-h

As you can see the file is mounted and viewed as a hard disk.

Without realizing it, just using the '-o loop "mount you have created a virtual device.

Cleaning Example 1 - dismantling, removal of the mount point and then delete the file:

  sudo umount / media / Disque_Virtuel /
 sudo rmdir / media / Disque_Virtuel /
 rm Disque_Virtuel.dd

I will now More>

Migration of a physical machine to a Windows 7 virtual machine VirtualBox (P2V)

1 year ago

Hello,

Today a small article on the migration of a Windows 7 to a Virtual Machine VirtualBox.

So I'll start with the two most common problems and finally end the process of data migration.

Problem 1:

To speed up the loading time, the installation of M $ Windows modifies the registry to not start the hardware drivers are not present. The problem is that here we will change the material and if the driver disk controller does not start, Windows will not find a boot disk! The solution: change the Windows registry before migration. I propose to do is use this file for editing the registry: Add_VBox_Hardware

Problem 2:

Windows has three different layers of abstraction equipment, managed by three different libraries: "Hal.dll (PC standard)" / "Halacpi.dll (for PC with ACPI)" / "Halaacpi.dll (for PC with ACPI and IO APIC) " More>
