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.

Fix included in qemu-kvm-rhev-2.3.0-7.el7
Comment 8 huiqingding 2015-08-07 05:14:00 UTC 
Reproduce this bug using the following version:
RHEL7.2 host:
kernel-3.10.0-302.el7.x86_64
qemu-kvm-rhev-2.3.0-6.el7.x86_64

RHEL7.1 host:
kernel-3.10.0-229.12.1.el7.x86_64
qemu-kvm-rhev-2.1.2-23.el7_1.8.x86_64

Steps to Reproduce:
1. boot a guest with a floppy (no image) in src RHEL7.2 host and RHEL7.1 host:
/usr/libexec/qemu-kvm -cpu Penryn -name test3 -S -machine pc-i440fx-rhel7.0.0,accel=kvm,usb=off -m 1000 -realtime mlock=off -smp 2,maxcpus=4,sockets=4,cores=1,threads=1 -uuid 7347d748-f7ce-448f-8d49-3d29c9bcac30 -no-user-config -nodefaults  -rtc base=utc -no-shutdown -boot strict=on  -drive file=/mnt/rhel7_1_qcow2,if=none,id=drive-ide0-0-0,format=qcow2 -device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1  -spice port=5901,addr=0.0.0.0,disable-ticketing,seamless-migration=on -k en-us -device qxl-vga,id=video0,ram_size=134217728,vram_size=67108864,vgamem_mb=16,bus=pci.0,addr=0x2 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3 -msg timestamp=on -monitor stdio -device intel-hda,id=sound3,bus=pci.0,addr=0x6 -device hda-duplex,id=sound3-codec0,bus=sound3.0,cad=0 -net none  -drive file=,if=none,id=drive-fdc0-0-0,format=raw,cache=none -global isa-fdc.driveA=drive-fdc0-0-0 -boot menu=on -serial unix:/tmp/tty0,server,nowait

2. Type "Ctrl+c" into grub command

3. Hit the tab key a few times after the fd0 (don't hit return)
grub > boot (fd0)

4. Do migration
(qemu) migrate -d tcp:10.66.8.244:5800

5. Carry on hitting the tab during migration

Actual results:
after step4 and step5, migration is failed and qemu-kvm in dst host quits with:
(qemu) qemu: warning: error while loading state for instance 0x0 of device 'fdc'
2015-08-07T03:56:04.069912Z qemu-kvm: load of migration failed: No such file or directory
Comment 9 huiqingding 2015-08-07 07:50:15 UTC 
Test this bug using the following version:
RHEL7.2 host:
kernel-3.10.0-302.el7.x86_64
qemu-kvm-rhev-2.3.0-15.el7.x86_64

RHEL7.1 host:
kernel-3.10.0-229.12.1.el7.x86_64
qemu-kvm-rhev-2.1.2-23.el7_1.8.x86_64

RHEL7.0 host:
kernel-3.10.0-123.17.1.el7.x86_64
qemu-kvm-rhev-1.5.3-60.el7_0.11.x86_64

Use the same steps of comment #8 to test, the results is as following:
Hosts           Machine Type         Results

7.2->7.1        -M rhel7.1.0         pass
