Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
Core dumped when live migration by using spice
Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.97.el6.
How reproducible:
100%
Steps to Reproduce:
1.start VM with spice in the src host
eg:/usr/libexec/qemu-kvm -M rhel6.0.0 -cpu qemu64,+sse2,+x2apic -enable-kvm -m 2G -smp 8,sockets=8,cores=1,threads=1 -name RHEL6_64 -uuid `uuidgen` -nodefconfig -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/RHEL6_11164.monitor,server,nowait -mon chardev=monitor,mode=control -rtc base=utc -boot c -drive file=/home/RHEL6.0.raw,if=none,id=drive-ide0-0-0,boot=on,format=raw,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -netdev tap,id=hostnet0,vhost=on -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:20:8d:62:99,bus=pci.0,addr=0x5 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -device usb-tablet,id=input0 -spice port=5930,disable-ticketing -vga std -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3
2.start the listening port in dest host <commandLine> -incoming tcp:0:5888
3.Do live migration
Actual results:
After migration ,qemu-kvm in the src core dumped with errror msg :qemu-kvm: migration.c:295: migrate_fd_cleanup: Assertion `s->state != 2' failed.

Expected results:
Additional info:
Do live migration with -vnc will not hit this issue.
test in qemu-kvm-0.12.1.2-2.96.el6 will not hit this issue.
According to comment #1,change the summary to "Qemu-kvm in the src host core dump when do migration by using spice"
After migration ,VM can be used successfully in the dest host.
Reproduced on qemu-kvm-0.12.1.2-2.106.el6,
Verified on qemu-kvm-0.12.1.2-2.108.el6.
Repeat the steps in comment #0.
Actual Results:
After migration ,No core dumped occurs in the src host.
The bug has been fixed already.
According to comment #8, change status to VERIFIED.
