[libvirt-users] virsh migrate ---no route to host

Hi, I am trying to migrate a guest domain from one node to another. I've tried several options of the virsh migrate command, but in vain. It seems to be a networking issue. I wanted to make sure that my setup is correct and that I am not missing anything. I've issued the below command on the source node (n0): [user@n0 ~]$ virsh --connect qemu:///system migrate --verbose Fedora-17-x86_64-1 qemu+ssh://n1/system error: unable to connect to server at 'n1:49156': No route to host I was wondering if you have any ideas on how to fix this issue. My current setup/configuration: 1. virsh version : 0.10.2 2. The user has all the necessary access control setup. I've referenced http://libvirt.org/auth.html I am able to locally and remotely connect to both the nodes. I am also able to start, stop and perform other actions on guest domains on local and remote nodes, e.g., /* access destination node */ [user@n0 ~]$ virsh --connect qemu+ssh://n1/system list --all Id Name State ---------------------------------------------------- /* access local node */ [user@n0 ~]$ virsh --connect qemu:///system list --all Id Name State ---------------------------------------------------- 2 Fedora-17-x86_64-1 running - Fedora-18-x86_64-DVD shut off 3. ssh keys are configured for password less access to both the nodes 4. I've opened ports 49152-49215 on the destination node i.e., n1. please see below. [user@n1 images]$ sudo iptables -L [sudo] password for user: Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:bootps ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT icmp -- anywhere anywhere ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh REJECT all -- anywhere anywhere reject-with icmp-host-prohibited ACCEPT tcp -- anywhere anywhere tcp dpts:49152:49215 ACCEPT tcp -- anywhere anywhere tcp spts:49152:49215 Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere 192.168.122.0/24 state RELATED,ESTABLISHED ACCEPT all -- 192.168.122.0/24 anywhere ACCEPT all -- anywhere anywhere REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-port-unreachable REJECT all -- anywhere anywhere reject-with icmp-host-prohibited Chain OUTPUT (policy ACCEPT) target prot opt source destination 5. I've restarted the libvirtd after updating the iptables. I don't think that is necessary, but did it anyway. I was wondering if I am missing something. Any help is greatly appreciated. Thanks, --Hari
