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)- 이 파라미터는
xend가 이전에 사용할 포트를 설정합니다. 값을 정확히 입력하신 후 앞의 주석 처리를 해제하시기 바랍니다. (xend-relocation-address )- 이 파라미터는
xend-relocation-server를 활성화한 후에 소켓 연결 재배치를 위해 대기하는 주소를 가리킵니다. 대기 중에 특정 인터페이스에 대한 이전을 제한합니다. (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.
위 파라미터를 설정한 후에 Red Hat Virtualization 호스트를 재시작하여 새 파라미터를 적용하시기 바랍니다.
