Kernel Version: 3.10.0-rc5+ Libvirt Version: 1.0.6 Qemu Version: 1.5.50 Steps to Reproduce: 1. Created the qemu-img create -f qcow2 vm.qcow2 11G on the destination host which is same as the source. 2. Started the guest on the source 3. Started the vncdisplay to monitor the guest 4. Initiated the migration "virsh migrate --live VM1 qemu+ssh://host-ip/system tcp://host-ip --verbose --copy-storage-all" 5. It started the copying the storage from souce to destination (conitinously monitored it was growing) 6. Guest on the destination was paused and was running on the source 7. At some point the VM on the source got shutdown and migration failed with "Unable to read from monitor: Connection reset by peer" Attached the libvirt debug logs.

With libvirt 1.0.5 and qemu 1.5 also we were facing the same issue, but with that even "Live migration with nfs also was not working".

[Bug 1192499] Re: virsh migration copy-storage-all fails with "Unable to read from monitor: Connection reset by peer"
The destination VM's log says: qemu: warning: error while loading state section id 1 This indicates that either there was an error on the destination while loading state or the migration stream got out of sync. Please check that QEMU on source and destination are identical. If you are running different versions of QEMU on source and destination this could be the cause. Try with qemu.git/master and a simple QEMU command-line (without libvirt): qemu-system-x86_64 -machine pc-i440fx-1.5,accel=kvm -m 4000 \ -drive file=/home/images/rhel64-64.qcow2,if=ide,format=qcow2,cache=none Use the same command-line on the destination but also add "-incoming tcp::1234". To start the migrate on the source, run "migrate -b tcp ::1234" in the QEMU monitor. If the failure can be reproduce on qemu.git/master in this way it will be easier to debug. I will be away next week and therefore unable to look into this more. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1192499 Title: virsh migration copy-storage-all fails with "Unable to read from monitor: Connection reset by peer" To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1192499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, I'm confused - what do you mean by you are using a fedora base? Are you talking about the VM, or the destination host?
