## What this script will do
6 years ago
It can handle:
6 years ago
- Virtual hard disk creation, backup and deletion.
- Basic network management: two ports are exposed to the host
machine (but you can add as many as you want). One of these
two ports is SSH (so admin gets simpler).
- Connection via SSH.
6 years ago
- Shared directory between host and guest.
- Last, but not least, running the virtual machine with all
these options.

## Setup information and usage
- You need a 64 bit machine with virtualization technology and more than 4 GB
of RAM.

- Modify `configvmrc` based on your needs.

- Install qemu:

# pacman -S qemu
- Create a new VHD and complete the OS installation:
$ ./qvm -c

$ ./qvm -i
- Optionally enable SSHD on the guest machine.
- Optionally create a new backup VHD:
$ ./qvm -b

- Now you can run the virtual machine either using the original or the backup
VHD. By deault if you run `./qvm` the virtual machine will run in graphics
mode using the backup hard disk.
- Optionally add the following in the gues machine's `/etc/fstab`, to enable
the shared directory automatically (no mount commands of any
