RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description huiqingding 2017-02-08 05:35:38 UTC 
Description of problem:
Migration failed from rhel7.4 to rhel7.3.z with rtl8139 nic card

Version-Release number of selected component (if applicable):
Source host(rhel7.4):
kernel-3.10.0-558.el7.x86_64
qemu-kvm-rhev-2.8.0-3.el7.x86_64

Destination host(rhel7.3.z):
kernel-3.10.0-514.11.1.el7.x86_64
qemu-kvm-rhev-2.6.0-28.el7_3.3.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot a rhel7.3 guest in source host:
# /usr/libexec/qemu-kvm \
-name rhel7 \
-S -machine pc-i440fx-rhel7.3.0,accel=kvm,usb=off \
-m 2048 \
-cpu Opteron_G4,check \
-realtime mlock=off \
-smp 4,maxcpus=4,sockets=4,cores=1,threads=1 \
-uuid 49a3438a-70a3-4ba8-92ce-3a05e0934608 \
-nodefaults \
-rtc base=utc,driftfix=slew \
-boot order=c,menu=on,strict=on \
-drive file=/mnt/rhel7.3.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,serial=f65effa5-90a6-47f2-8487-a9f64c95d4f5,cache=none,discard=unmap,werror=stop,rerror=stop,aio=threads \
-device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0 \
-netdev tap,id=hostnet2,vhost=on,script=/etc/qemu-ifup \
-device rtl8139,netdev=hostnet2,id=virtio-net-pci2,mac=4e:63:28:bc:c1:75,bus=pci.0,addr=0x5,multifunction=off \
-monitor stdio \
-qmp tcp:0:4466,server,nowait -serial unix:/tmp/ttym,server,nowait \
-spice port=5910,addr=0.0.0.0,disable-ticketing,seamless-migration=on \
-device qxl-vga,id=video0,ram_size=134217728,vram_size=67108864,vgamem_mb=16,bus=pci.0,addr=0x2 \

2.boot the guest in destination host with "-incoming tcp:0:5800"

3.do migration
(qemu)migration -d tcp:10.73.72.58:5800

Actual results:
after step3, migration failed and destination qemu-kvm quits with
(qemu) qemu-kvm: savevm: unsupported version 5 for '0000:00:05.0/rtl8139' v4
qemu-kvm: load of migration failed: Invalid argument

Expected results:
migration can be finished normally.

Comment 1 huiqingding 2017-02-08 09:23:23 UTC 
Do vmstate check and the result is as following:
# python vmstate-static-checker.py -s rhel7.3.json_7.3 -d rhel7.4.json_7.3 
Section "e1000e", Description "e1000e": expected field "intr_state", got "core.rxbuf_min_shift"; skipping rest
Section "rtl8139", Description "rtl8139": expected field "tally_counters", got "tally_counters.TxOk"; skipping rest
Comment 3 Dr. David Alan Gilbert 2017-02-09 15:19:36 UTC 
Yep, easily reproduced by :

./x86_64-softmmu/qemu-system-x86_64 -machine pc-i440fx-rhel7.3.0,accel=kvm,usb=off -device rtl8139 -nographic
