明显可以看出pdpe1gb被加入到列表中两次。去重。

修改方法：

 #edit by ttx 2014-11-25
        features_list = info['features']
        features_list = list(set(features_list))
        for f in features_list:
            cpu.add_feature(vconfig.LibvirtConfigCPUFeature(f))

报secret_uuid错误则是所有ceph的secret_uuid必须一致，且nova.conf的rbd_secret_uuid = 8b45ead4-3cc9-4700-b85a-107050eeea8c也必须一致才能迁移。

上述错误就是nova。conf的uuid与virsh secret-list不一致，导致。

错误：

2014-11-18 19:39:20.559 11921 WARNING nova.compute.manager [-] Found 4 in the database and 3 on the hypervisor.

2014-11-18 19:39:46.968 11921 ERROR nova.virt.libvirt.driver [-] [instance: cb91421e-5dfa-4d2b-8d8a-c6b0f51b2bf6] Live Migration failure: unsupported configuration: Unable to find security driver for label selinux

解决办法：

vim /usr/local/libvirt/etc/libvirt/qemu.conf

#security_driver = "selinux"

修改为：

security_driver = "none"

将selinux修改为none
