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.

...
  <features>
    <acpi/>
    <apic/>
    <pae/>
  </features>
...

2.migrate to 7.1 host

# virsh migrate test3 qemu+ssh://10.66.6.12/system --live
error: internal error: early end of file from monitor: possible problem:
qemu: warning: error while loading state for instance 0x1 of device 'apic'
2015-03-30T02:09:03.553100Z qemu-kvm: load of migration failed: No such file or directory

Comment 4 Dr. David Alan Gilbert 2015-05-05 10:31:58 UTC 
Should be fixed in qemu-kvm-rhev-2.3.0-1 due to the fix as part of bz 1210050
Comment 7 huiqingding 2015-07-01 07:07:43 UTC 
Reproduce this bug using the following version:
RHEL7.1 host:
qemu-kvm-rhev-2.1.2-23.el7_1.4.x86_64
kernel-3.10.0-229.7.2.el7.x86_64

RHEL7.2 host:
qemu-kvm-rhev-2.2.0-8.el7.x86_64
kernel-3.10.0-287.el7.x86_64

Reproduce steps:
1. boot a guest on RHEL7.2 host:
# /usr/libexec/qemu-kvm -cpu Opteron_G2 -name test3 -S -machine pc-i440fx-rhel6.5.0,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 -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/test3.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -boot strict=on -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x6 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x5 -device usb-ccid,id=ccid0 -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 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/r6.agent,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=2,chardev=charchannel0,id=channel0,name=org.qemu.guest_agent.0 -chardev spicevmc,id=charchannel1,name=vdagent -device virtserialport,bus=virtio-serial0.0,nr=9,chardev=charchannel1,id=channel1,name=com.redhat.spice.0 -device usb-tablet,id=input0 -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

2. boot the guest on dst RHEL7.1 host using "-incoming tcp:0:5800"

3. do migration
(qemu) migrate -d tcp:10.66.106.84:5800

Actual results:
qemu-kvm on dst host quits with the error info:
qemu: warning: error while loading state for instance 0x1 of device 'apic'
2015-07-01T07:02:11.822939Z qemu-kvm: load of migration failed: No such file or directory
Comment 8 huiqingding 2015-07-01 07:39:16 UTC 
Test this bug using the following version:
RHEL7.1 host:
qemu-kvm-rhev-2.1.2-23.el7_1.4.x86_64
kernel-3.10.0-229.7.2.el7.x86_64

RHEL7.2 host:
qemu-kvm-rhev-2.3.0-6.el7.x86_64
kernel-3.10.0-287.el7.x86_64

Use the same steps of comment #7 to do test, the results is as following:
after step3, migration can be finished normally, inside guest, run "dmesg", no error info.

I also test -machine pc-i440fx-rhel7.1.0/pc-i440fx-rhel7.0.0, the results are same.

Based on the result, I think this bug is fixed.
