Xen Virtualization Series (v) Methods for expanding disk space by Xen virtual machines Two

With the extensive use of virtualization technology, the use of virtualization thinking and start more, such as direct expansion of disk space in this case, I recommend a new disk to add a way to fit the normal physical machine to use the way.

Another way to increase disk space is to extend the space of an existing disk directly, in this way.

1. View the virtual machine configuration file

[Root@node1 data]#

[Root@node1 data]# XM List

Name ID Mem (MiB) Vcpus state time (s)

Domain-0 0 1744 1 R-----34.4

2. test02 Virtual machine using/data/test02.img

[Root@node1 data]#

[Root@node1 data]# cat/etc/xen/test02

Name = "test02"

UUID = "Cc49eaea-fb0c-5239-c055-bdafcf210cab"

MAXMEM = 512

Memory = 512

Vcpus = 1

bootloader = "/usr/bin/pygrub"

On_poweroff = "Destroy"

On_reboot = "Restart"

On_crash = "Restart"

disk = ["Tap:aio:/data/test02.img,xvda,w"]

Vif = ["Mac=00:16:3e:44:ee:10,bridge=xenbr1,script=vif-bridge"]

[Root@node1 data]#

3. Directly extend existing virtual disk space
