18.23. Configurando a Máquina Virtual de Migração Ativa
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)- Este parâmetro ajusta a porta que o
xendusa para migração. Este valor é correto, mas lembre-se de remover o comentário que o precede. (xend-relocation-address )- Este parâmetro é o endereço que recebe as conexões de soquete de recolocação, depois de habilitar o
xend-relocation-server. Ao receber, ele restringe a migração a uma interface específica. (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.
Após configurar estes parâmetros, você deve reiniciar a máquina para a Tecnologia de Virtualização Red Hat para aceitar seus novos parâmetros.
