When I attempt to set up remus between two machines I get an error in the remus log file, I can’t understand why it occurs, I have the same vms running on both systems, so attempted replication shouldnt be an issue. The Log file is as follows:
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
tc filter add dev vif1.0 parent ffff: proto ip pref 10 u32 match u32 0 0 action
mirred egress redirect dev ifb0
RTNETLINK answers: No such file or directory
We have an error talking to the kernel

The remus command used to get this file is as follows:
remus -i 100 sles11-sp1-xm BackupMachineIP >/var/log/xen/domU-sles11-sp1-24-09-12.log 2>&1 &
BackupMachineIP is setup as the name for the IP address of the backup device, the contents of xm list and the loopback device setups on each machine are as follows:
