We are testing the upstream KVM with :
Kernel, Qemu, Libvirt, Virt-Manager is built from the source (git).
kernel version : 3.9.0+
qemu version : QEMU emulator version 1.5.0
libvirt version : 1.0.5
virt-install : 0.600.3
I have followed the below steps to test the "Live migration w/o
shared storage" feature :
1. Created the qemu-img create -f qcow2 vm.qcow2 12G 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 rhel64-64
qemu+ssh://9.126.89.202/system --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 shutdown and got an error on
the vnc display as " Viewport: write: Broken pipe (32)" and the
VM on the destination was undefined.
Below is the libvirt debug log, please let me with your comments.
Debug log:
--------------
What about /var/log/libvirt/qemu/rhel64-64.log? That is the QEMU
command-line and stderr log.
I have attached all source and destination logs, including the sosreport
of both source and destination in the bug.

Also can you try without copy-storage-all just to see if migration
completes successfully? The guest will act weird once it migrates since
the disk is zeroed but it will isolate the failure to
--copy-storage-all.
Without copy-storage-all (meaning with NFS shared storage the migration
works fine).

Please let me know if you need more info.
