I have a tiny embedded server (acrosser model) Intel Celeron with only 400MHz and 512MB Mem total. Before I upgraded debian to squeeze I used Xen, now its time to use OpenVZ.
Reasons:
- My tiny hardware:)
- Container virtualization – I can use more virtual machines
- Less memory usage – Container cannot boot
OpenVZ kernel and the vzctl and vzquota packages are available in the Debian repositories, so we can install them as follows:

There are a lot virtual emulators for windows, but most of them aren’t free and forbidden for commercial use. QEMU emulator released under GPL-license and works very well on windows. (I tested it only Windows Server 2003)

Some days ago I started to give up my VMWare Workstation Server (version: 6.5.1 build-126130) that is running on Debian Lenny.
The reason was it’s very difficult to upgrade (you see my installation is a little bit outdated:)) and maintain.
The first step is to migrate to VirtualBox running. And I wrote this little tutorial to migrate VMWare VMDK Image to VirtualBox.
Step 1:
Start Virtualbox

Step 2:
File -> Virtual Media Manager

I was playing again a little bit with KVM virtualization and found one very strange thing, my KVM kills guests instead of properly shutdown.
KVM just sends an ACPI signal to the guest to tell it to shut down. Of course, this means the guest needs to do something useful when it receives the signal. By default Debian/Ubuntu guests don’t understand ACPI signals.
The solution is: install acpid in each guest.
1 | aptitude update ; aptitude install acpid |
After installing this, the ’shutdown’ and ‘reboot’ buttons worked perfectly!
