Created attachment 513773 [details] vdsm.log Description of problem: When connection between hosts (SPM and non-SPM) crashes during a VM migration, there's no timeout - the VM stays in locked mode, vdsm on SPM host tries to migrate the vm repeatedly (possibly forever). Version-Release number of selected component (if applicable): vdsm-4.9-82.el6.x86_64 libvirt-0.9.2-1.el6.x86_64 qemu-kvm-0.12.1.2-2.171.el6.x86_64 How reproducible: 100 % Steps to Reproduce: 1. Have a working setup - 2 hosts (without fencing), NFS storage (probably irrelevant) 2. Start a vm (on SPM host), when it's up perform migration to the non-SPM host 3. Right after it starts block communication between SPM and non-SPM host using iptables (but not between hosts and storage!) Actual results: Vdsm keeps trying to migrate the vm (possibly forever), vm is in locked mode Expected results: Migration fails with proper error shown to user after some timeout - when data transferred to the second host stays on 1% for more then 10 mins it definitely means that something isn't ok.

Verified - vdsm-4.9-86.el6 - timeout was set in vdsm therefore migration (from vdsm point of view) can't be proceeding forever.
