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 migratecommand). Live migration can be done from the same command. However there are some additional modifications that you must do to the
xend-configconfiguration file. This example identifies the entries that you must modify to ensure a successful migration:
- 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.
- 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.
在設定這些參數後，您必須重新啟動主機，因此 Red Hat 虛擬化才能接受這些新參數。
