dmesg-vmcore.txt file (-M rhel6.4.0)
When migrate guest with "-M rhel6.4.0" with same steps, guest core dump during S4 after migration.
Retest the following scenarios suggested by Amit: (1) with -M rhel6.5.0 machine type: Actually comment 0 is using "-M rhel6.5.0" already. So, still hit the problem. (2) Without virtio device. Still failed with same phenomenon. (3）Test a RHEL6.5-64 guest (comment 0 is using a rhel7.0 guest): With and without virtio device: failed,same phenomenon. "top" shows 100% cpu consumption, and I can not get any log from the isa serial console. Orit, didn't you look at something similar? There was one where the firmware sizes are different across 6.5 and 7.0, but this doesn't seem to be that (firmware is migrated too). Anything that strikes you about this?

We have problems with restarting guest after migration from 6.5 to 7.0, could be related but I'm not sure. Created attachment 886768 [details] vmcore.txt (first time s4 after migration) with comment 7 build Created attachment 886769 [details] vmcore.txt (second time s4 after migration) with comment 7 build Created attachment 893546 [details]
the screenshot that win7sp1-64 guest cannot resume after S4
I migrate a win7sp1-64 guest from RHEL6.6 host to RHEL7.0 host, do S4 and then start guest on dest host, the guest cannot resume. The screenshot is as the attachment file.
RHEL6.6 host:
kernel-2.6.32-459.el6.x86_64
qemu-kvm-0.12.1.2-2.425.el6.x86_64
RHEL7.0 host:
kernel-3.10.0-123.el7.x86_64
qemu-kvm-1.5.3-60.el7_0.2.x86_64
qxl driver of win7sp1-64 guest is qxl-win-0.1-21.
Don't do migration, on RHEL6.6 host, boot win7sp1-64 guest and do S4. the guest can resume successfully. On RHEL7.0 host, boot win7sp1-64 guest and do S4. the guest can resume successfully.
The command line is as following:
