Installation on Ubuntu
Virtualization in the host machine
Note that even the host machine is 64-bit, if the vT is not available/enabled in the BIOS, we cannot install 64-bit OS in the guest machine.
Virtual box guest addition
Install guest addition for virtualbox on Debian See the link [1]
virtual machine software benchmark
Trouble Shooting
virtualbox failed to create the host-only network
Virtualbox (*.deb) was downloaded from virtualbox website. However, when I want to create a host-only network, I have to execute
sudo /etc/init.d/vboxdrv setup sudo apt-get install dkms build-essential linux-headers-$(uname -r)
This also solves the error "Kernel driver not installed (rc=-1908)".
Suppose we want to share the <Downloads> folder from host to guest.
sudo nano /etc/fstab sudo mkdir /mnt/Downloads # Add a new line # Downloads /mnt/Downloads/ vboxsf defaults 0 0 sudo mount -a
Note that the auto-mount option is supposed to work automatically. See https://www.virtualbox.org/manual/ch04.html#sf_mount_auto. But I get a permission denied error. The reason is we have to add the current user to the group vboxsf.
sudo usermod -a -G vboxsf USERNAME # logout and login again
See http://www.cyberciti.biz/faq/howto-linux-add-user-to-group/ for more examples of usermod command.
Use VirtualBox
Increase the guest machine space
Different networks
Clone vs Import/Export appliance
Clone will create a new VM directory (including *.vdi) on the same machine.
Import/Export appliance (*.ova) allows to transport the appliance to a new machine. The appliance will not be touched on the new machine.
vmware
apt-get update apt-get install build-essential module-assistant m-a prepare cd Downloads tar xzvf /media/cdrom0/VMwareTools-9.2.0-799703.tar.gz cd vmware-tools-distrib ./vmware-install.pl [Accept all default] shutdown -r now
Emulation vs virtualization
Virtualization allows users to configure virtual machines outfitted with similar hardware and processors as the host system, whereas emulation simulates different hardware and processor configurations in software.
Emulators are what allow you to run old Commodore 64 or NES games on a PC, for example.
