Using a template may cause the virtual machine to have insufficient hard disk capacity and can be stored as data by adding a single hard disk.1. First use the DD command to create an image file size 10G under the default path:
DD bs=1m count=10240 If=/dev/zero of=/var/lib/libvirt/images/guest1_data.img
You can also use the QEMU-IMG command to create a specific reference: Cent

A hard disk is an external storage device for magnetic media, on each side of the platter, a plurality of concentric circles with the axis of rotation and a certain magnetic density are divided into tracks (Track), each of which is divided into several sectors (sector), and the data is stored on the hard disk by sector.

So to keep the head of the drive in the disk radius, the drive motor (seek motor) of the head arm will continue to pass current. And let the head arm in the hard disk idle for a few minutes immediately after the unloading action, return to the docking rack, both to hel
More and more users have chosen the model for installing SSD drives when they buy Macs. SSD can make OS X run more smoothly, but its 256G, 128G capacity, more and more can not meet the needs of people. Connecting an external hard drive to your Mac is a temporary solution. OS x is well compatible, making most external
Jump out of hard drive misunderstandingSeveral common sense questions that have been misleading Gao Peng for many years are:1. Hard Disk logical bad sectors can be repaired, but physical bad sectors cannot be repaired. The actual situation is that bad channels are not divided into logical and physical bad channels. I don't know who invented these two concepts. Th
are not recognized can also be repaired, but it is difficult to partition when the 0 channels are bad.This is misleading. For example, if you have not collected and studied foreign-language materials for a long time, you cannot say that you have used them as your creed for a long time. There are many professional hard drive repair forums in foreign countries, where you can find that

Hard drives with different SCSI specifications:
With 68-pins Wide SCSI connectors, you can transfer data using the 16-bit channel width.
With 60-pins narrow SCSI connectors, data can only be transmitted in a 8-bit channel width.
