[Qemu-devel] [KVM] guest remote migration fails

[pradeep]

Migration of guest(both local and remote) fails with 2.6.37-rc8 host

Test Procedure:
-----------------------
A is the source host, B is the destination host:
1. Start the VM on B with the exact same parameters as the VM on A, in
migration-listen mode:
B: <qemu-command-line> -incoming tcp:0:4444 (or other PORT))
2. Start the migration (always on the source host):
A: migrate -d tcp:B:4444 (or other PORT)
3. Check the status (on A only):
A: (qemu) info migrate                   


Expected results:
-------------------------
Migration should complete without any error

Actual results:
--------------------
qemu-system-x86_64: VQ 2 size 0x40 Guest index 0xf000 inconsistent with
Host index 0x0: delta 0xf000
load of migration failed

Guest OS:
------------------
