Hi,

Found that the 3.6 introduces a Regression !

migrate w/ e1000 nic will fail

qemu# warning: error while loading state for instance 0x0 of device 0000:00:03.0/e1000'
load of migration failed


And this issue didn't found on el6_3.5 or the latest RHEL.6.4 
qemu-kvm-0.12.1.2-2.334.el6.x86_64

Looks like 3.6 missed some patch.

Regards,
Xiaoqing Wei.

The patch fixed my original issue

now PCI Compliance Test job can pass on qemu-kvm-0.12.1.2-2.295.el6_3.6.

Hello, Xiaoqing

I just tried migration between qemu-kvm-295_3.6 and rhel6.4 version qemu-kvm-334 with e1000 emulated nic, but have no problem. Migration finished successfully.
Could you help check the following options:
1) Do you use spice to test? Cross version migration with spice is broken due to bug 869981.
2) Is the pci address for each pci device (especially e1000 in your case) are matching the configuration in destination host?  Migration will fail if the pci addr are not matched before and after migration.
3) Could you provide your command line?

p.s. 
My command line:

Hi Michael

Here is some summarize for the issue xwei raised in comment 18.

1) Migration failed with e1000 nic between two rhel6.3-z latest build, qemu-kvm-295_3.6 and qemu-kvm-295_3.6. Re-test with virtio nic, have no problem.

2) Migration between rhel6.3-z (qemu-kvm-295_3.6) and rhel6.4, passed. (Ping-pong migration passed.)

3) Migration between rhel6.3-z (qemu-kvm-295_3.6) and rhel6.3 released version, passed. (Ping-pong migration passed.)

4)I tried your build in comment 13, hit the issue as well.

Thanks,
Qunfang

Re-verified on qemu-kvm-0.12.1.2-2.295.el6_3.8 ,PCI Compliance Test can pass as well

Correction: the verify version should be qemu-kvm-rhev-0.12.1.2-2.295.el6_3.8.We never run svvp test over qemu-kvm package after rhel6.3

Mike

ve-verified on qemu-kvm-0.12.1.2-2.295.el6_3.8 , job can pass as well
