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:

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!
