Centos/ubuntu methods for mounting VMDK, VDI as block devices (non-vdfuse)

Because Vdfuse only support virtualbox4.x, is now in the new version of Ubuntu or CentOS canceled, change the idea, you can use the QEMU+NBD method to mount Vmdk,vdi,vhd,vhdx and other formats of the disk.

The following methods are implemented on CENTOS7.

1, compile the kernel, compile NBD as module.

Yum Groupinstall "Developmenttools" yum install gcc ncurses ncurses-devel bcyum updatewget https://www.kernel.org/pub/ LINUX/KERNEL/V4.X/LINUX-4.0.TAR.XZTAR-XF linux-4.0.tar.xz-c/usr/src/cd/usr/src/linux-4.0/make Menuconfig

On the configuration screen, go to the menu

Device Drivers→block Devices

Selected:

<M> Network block device support

Save, Exit:

< SAve >

< Exit >

Roughly like:

. config-linux/x86 4.0.0 Kernel Configuration

To compile the kernel again:

Makemake Modules_install Install

Upon completion, reboot

2, modify the configuration:

Set the new kernel to start automatically:

Grub2-set-default 0

To set the NBD module to load automatically:

Build file:/etc/sysconfig/modules/nbd.modules

Content:

Modprobe NBD max_part=16

Reboot.

3. Installation configuration qemu-img and QEMU-NBD

Yum Install qemu-img

4. Create a file and mount it:

Qemu-img create-f VPC test.vhd 10G//Create a dynamic mode 10G VHD format file qemu-img create-f vmdk test.vmdk 10G//Create a dynamic mode 10G vmdk format file Qem U-nbd-c/dev/nbd0 TEST.VMDK//Attach TEST.VMDK to/dev/nbd0 device files
