Virtualbox as a sysadmin tool
Tagged Under : administrador de sistemas, servicio, servicios, virtualbox, virtualización, vrdp
Besides the port fordwarding, VirtualBox has another very useful feature for system administrators: running a virtual machine WITHOUT graphical interface.
We suppose this situation: we have a virtualized server (it doesn’t matter if it’s linux, Windows, Solaris,…), must run every time you start the system and must also consume less resources as possible.
The solution seems simple. VirtualBox brings commands: vboxsdl and vboxheadless. Both allow to run a virtual machine without open virtual machines manager.
vboxsdl run the virtualized system in a window graphical interface, in fact is the same as running the system from the virtual machines manager, but if we call it directly, we avoid having to resort to this.
vboxsdl -startvm "VM_NAME"
vboxheadless run virtualised system, but without raising any graphical interface, making it possible to boot only with the console. This is especially useful for servers that dispenses with the Xserver.
vboxheadless -startvm "VM_NAME"
If we can not see the virtual machine, how would you control?
Here I have a couple of tips used in Windows XP as host, Windows 2000 Server as guest, but the same should be applied in a Linux and other systems.
