HI,
thanks for your answer.
I'm not sure if I get your hint.
Did you suggest me to use DNAT on VM1 and VM3?
In particular, you suggest me to do this on VM1:
iptables -t nat -A PREROUTING -i eth0 -j DNAT --to <IP_VM2>
Is it right?
Just to be sure, what I want is to send a packet from VM1 to VM3, but this packet
have to pass through VM2.
Should I do something in VM2,like enable IP forwarding?
Sorry for these (maybe) newbie question.
Thanks,
M

FENCE_AGENT(8) System Manager's Manual FENCE_AGENT(8)
NAME
fence_virtd - Fencing host for virtual machines
DESCRIPTION
fence_virtd is a host daemon designed to route fencing requests for virtual machines.
Fence_virt and fence_xvm talk to fence_virtd, which supports multiple backend plugins, including:
- libvirt for single-node operation
- Cluster Checkpoints when using Linux-cluster release 3.0.0 or later
- libvirt-qpid for multi-node, non-cluster operation
For compatibility, fence_xvm from linux-cluster release 2 may talk to fence_virtd.
fence_virtd accepts a few options on the command line, but most options are read from fence_virt.conf.
PARAMETERS
-d Specify debug level, e.g. "-d99"
-c Interactively prompt user for configuration information
-f Specify an alternate configuration file instead of /etc/fence_virt.conf
-F Do not fork into background after starting (overrides any setting in fence_virt.conf)
-w Wait for backend to be available (overrides any setting in fence_virt.conf)
