Bug detailed description:
--------------------------
after guest live migration, the guest will hang, and ping IP fail
note:
1. after guest save/restore, the guest will hang, and ping IP fail
2. This should be a qemu-kvm bug.
kvm + qemu-kvm = result
205befd9 + ca916d37 = bad
205befd9 + f03d07d4 = good
Reproduce steps:
----------------
1.Start a TCP daemon for migration
qemu-system-x86_64 -enable-kvm -m 2G -smp 2 -net nic,macaddr=00:12:34:56:13:45
-net tap,script=/etc/kvm/qemu-ifup rhel6u2.qcow -incoming tcp:localhost:4444
2. create guest
qemu-system-x86_64 -enable-kvm -m 2G -smp 2 -net nic,macaddr=00:12:34:56:13:45
-net tap,script=/etc/kvm/qemu-ifup rhel6u2.qcow
3. migrate tcp:localhost:4444
Current result:
----------------
guest hang
Expected result:
----------------
after live/migration or save/restore, the guest works fine
