当我尝试在两台机器之间设置remus时，我在remus日志文件中收到一个错误，我无法理解为什么会发生，我在两个系统上都运行了相同的vm，因此尝试复制应该不是问题。日志文件如下
Disk is not replicated: phy:/dev/loop0,xvda,w
Disk is not replicated: phy:/dev/loop1,xvdb,w
tc qdisc add dev vif1.0 ingress
RTNETLINK answers: File exists

用于获取此文件的remus命令如下：
remus -i 100 sles11-sp1-xm BackupMachineIP >/var/log/xen/domU-sles11-sp1-24-09-12.log 2>&1 &
将BackupMachineIP设置为备份设备IP地址的名称，每台机器上的xm列表和回送设备设置的内容如下：
XM清单
