Common commands of VirtualBox in Linux are used to create virtual machines for dishes who are new to VirtualBox through a graphical interface, which is easier for those who have used Windows, however, after creating a VM, we need to use commands on the host machine to monitor various VMS. The following describes several frequently-used commands that I have used: 1. view existing VMS # view all VMS [root @ hpctest ~] # Vboxmanage list vms "RHEL5.6 _ for_HPC2.1" {a6f73f9a-4f78-4b63-9a96-faa235989633} "RHEL6.1 _ detail" {detail} "RHEL6.1 _ for_HPC3.1" {b77e85bc-3f1b-4333-8369-4685a70d6a33} "CentOS6U2" {detail} "RHEL6.1 _ for_HPC3.2 "{ 2469af71-c5f6-443a-97b9-ed8ad723e0e5} # view the currently running VM www.2cto.com [root @ hpctest ~] # Vboxmanage list runningvms "CentOS6U2" {19d08d91-1bf8-49e3-ada8-b7c99c4ad24c} "RHEL6.1 _ for_HPC3.2" {region} 2. to start a VM, you need the name or UUID of the VM (something in the above {}) [root @ hpctest ~]. # Vboxmanage startvm "RHEL6.1 _ for_HPC3.1" Waiting for VM "RHEL6.1 _ for_HPC3.1" to power on... VM "RHEL6.1 _ for_HPC3.1" has been successfully started.3. stop a VM. vboxmanage can only be stopped by the Poweroff command, which is equivalent to directly shutting down the power supply. If there is a running program on the VM, it is best not to execute this command [root @ hpctest ~] # Vboxmanage controlvm "RHEL6.1 _ for_HPC3.1" poweroff0 %... 10%... 20%... 30%... 40%... 50%... 60%... 70%... 80%... 90%... 100% the commands I have used will be updated in the future. Of course, the best way is to directly look at help or man's author DanielXLee.
