18.23. Configuration de la migration en direct de machines virtuelles
Red Hat Virtualization can migrate virtual machines between other servers running Red Hat Enterprise Linux 5.1 with Virtualization. Further, migration is performed in an offline method (using the
xm migrate command). Live migration can be done from the same command. However there are some additional modifications that you must do to the xend-config configuration file. This example identifies the entries that you must modify to ensure a successful migration:
(xend-relocation-server yes)- The default for this parameter is 'no', which keeps the relocation/migration server deactivated (unless on a trusted network) and the domain virtual memory is exchanged in raw form without encryption.
(xend-relocation-port 8002)- Ce paramètre détermine le port utilisé par
xendpour la migration. La valeur est correcte, veuillez simplement vous assurer que vous enlevez le commentaire qui est placé devant. (xend-relocation-address )- Ce paramètre représente l'adresse qui écoute les connexions socket de délocalisation. À l'écoute, elle restreint la migration vers une interface particulière.
(xend-relocation-hosts-allow )- This parameter controls the host that communicates with the relocation port. If the value is empty, then all incoming connections are allowed. You must change this to a space-separated sequences of regular expressions (such as
xend-relocation-hosts-allow- '^localhost\\.localdomain$'). A host with a fully qualified domain name or IP address that matches these expressions are accepted.
Après la configuration de ces paramètres, vous devez redémarrer l'hôte pour que la virtualisation Red Hat accepte vos nouveaux paramètres.
