Linuxin päätejärjestelmä (http://www.ltsp.org) palvelee, ei vain luokallista päätteitä, vaan satoja, jopa tuhansia päätteitä, kun käytetään LTSP-klusteria.

Tämä ei ole ohje LTSP-klusterin käyttöönottamista varten. Sellainen tehdään tälle sivulle LTSP-työpajan jälkeen: http://wiki.ubuntu-fi.org/LTSP5_Ty%C3%B6paja_2009_2

Tälle sivulle on koottu asennuksen yhteydessä muokatut asetustiedostot, jotta niitä voidaan käyttää LTSP-työpajan asennuksessa.

Tässä tehty asennus KVM-virtuaalipalvelimelle perustuu tähän Stéphane Graberin ohjeeseen: https://wiki.stgraber.org/LTSP-Cluster/Documentation/OpenVZSetup

LTSP-klusteri KVM-virtuaalipalvelimella

Tässä asennuksessa on ensin asennettu Ubuntu 9.04-koneeseen KVM-virtuaaliympäristö. Sen asennuksesta ja käytöstä löytyy omat ohjeensa: http://wiki.ubuntu-fi.org/KVM
