  3. Ciclo de vida das VMs

  4. Classes

  5. Configuração Arquivo /et c/xen/xend-config.sxp (xen-api-server ((9363 none '^localhost$ gta\\.ufrj\\.br$') (unix)))

  6. Exemplo from xen.xm.XenAPI import Session session = Session('http://itaipava:9363/') session.login_with_password(' ', ' ') for vm_uuid in session.xenapi.VM.get_all(): if "xenvm1.gta.ufrj.br" == session.xenapi.VM.get_name_label(vm_uuid): vm = vm_uuid session.xenapi.VM.migrate(vm,'floresta',True,{})

  7. Exemplo 2 Python session = session.login_with_password("user", "passwd“) XML <?xml version=‘1.0’?> <methodCall> <methodName>session.login_with_password</methodName> <params> <param> <value><string>user</string></value> </param> <param> <value><string>passwd</string></value> </param> </params> </methodCall>

  8. Concorrente Libvirt Suporte Xen, QEMU, KVM Linux, LXC Linux, OpenVZ, User Mode Linux e VirtualBox Configuração Arquivo /et c/xen/xend-config.sxp (xend-unix-server yes) Exemplo import libvirt conn = libvirt.open('xen:///') vm = conn.lookupByName('winxp') dconn = libvirt.open('xen+ssh://floresta/') vm.migrate(dconn,1,None,None,0)
