Quando eu tento configurar o remus entre duas máquinas, recebo um erro no arquivo de log remus, não consigo entender porque ocorre, tenho a mesma vms em execução nos dois sistemas, portanto, a tentativa de replicação não deve ser um problema. O arquivo de log é o seguinte
Disk is not replicated: phy:/dev/loop0,xvda,w
Disk is not replicated: phy:/dev/loop1,xvdb,w

O comando remus usado para obter este arquivo é o seguinte:
remus -i 100 sles11-sp1-xm BackupMachineIP >/var/log/xen/domU-sles11-sp1-24-09-12.log 2>&1 &
O BackupMachineIP é configurado como o nome do endereço IP do dispositivo de backup, o conteúdo da lista xm e as configurações do dispositivo de loopback em cada máquina são as seguintes:
