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 2014-08-15 08:17:37 UTC 
DescrRHELiption of problem:
Boot a guest with "-vga qxl", do migation, after migration, GUI console of the guest is hang. On the host, can ping guest and use ssh connect the guest.

Version-Release number of selected component (if applicable):
src host:
qemu-kvm-1.5.3-67.el7.x86_64
kernel-3.10.0-145.el7.x86_64
dst host:
qemu-kvm-1.5.3-67.el7.x86_64
kernel-3.10.0-145.el7.x86_64

RHEL7.1 guest:
kernel-3.10.0-145.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. boot a RHEL7.1 guest with "-vga qxl" on src host:
# /usr/libexec/qemu-kvm -name virt-tests-vm1 -M pc -nodefaults -spice port=5901,password=redhat-vga,disable-ticketing -vga qxl -global qxl-vga.vram_size=33554432  -device virtio-scsi-pci,id=virtio_scsi_pci0 -drive id=drive_image1,if=none,cache=writethrough,snapshot=off,aio=native,file=/mnt/rhel7_1.qcow2 -device scsi-hd,id=image1,drive=drive_image1 -device virtio-net-pci,mac=9a:08:09:0a:0b:0c,id=idqiB5iJ,netdev=idlmunRA -netdev tap,id=idlmunRA,vhost=on,script=/etc/qemu-ifup -m 2048 -smp 2,maxcpus=2,cores=1,threads=1,sockets=2 -cpu SandyBridge  -rtc base=utc,clock=host,driftfix=slew  -monitor stdio

2. boot a RHEL7.1 guest on dst host:
# /usr/libexec/qemu-kvm -name virt-tests-vm1 -M pc -nodefaults -spice port=5901,password=redhat-vga,disable-ticketing -vga qxl -global qxl-vga.vram_size=33554432  -device virtio-scsi-pci,id=virtio_scsi_pci0 -drive id=drive_image1,if=none,cache=writethrough,snapshot=off,aio=native,file=/mnt/rhel7_1.qcow2 -device scsi-hd,id=image1,drive=drive_image1 -device virtio-net-pci,mac=9a:08:09:0a:0b:0c,id=idqiB5iJ,netdev=idlmunRA -netdev tap,id=idlmunRA,vhost=on,script=/etc/qemu-ifup -m 2048 -smp 2,maxcpus=2,cores=1,threads=1,sockets=2 -cpu SandyBridge  -rtc base=utc,clock=host,driftfix=slew  -monitor stdio -incoming tcp:0:5800

3. do migration
(qemu) migrate -d tcp:10.66.9.152:5800

Actual results:
after step3, GUI console of the guest is hang. The host can ping guest and can use ssh to coonect to the guest. 

Expected results:
GUI console of the guest should be normal.

Additional info:
I check dmesg inside guest after migration, not found error info.
Comment 1 huiqingding 2014-08-15 08:18:59 UTC 
I test "-vga cirrus", not hit this problem.
Comment 2 huiqingding 2014-08-15 08:21:10 UTC 
I also test qemu-kvm-1.5.3-60.el7.x86_64, qemu-kvm-1.5.3-65.el7.x86_64, not hit this problem.

I test qemu-kvm-1.5.3-66.el7.x86_64, hit this problem.

Based on this comment, add "Regression" keywords.
Comment 4 huiqingding 2014-08-15 08:23:31 UTC 
I also test qemu-kvm-rhev-2.1.0-1.el7.x86_64, not hit this problem, only hit this bz1130356.
Comment 7 Dr. David Alan Gilbert 2014-10-21 13:22:01 UTC 
I can confirm it is something between -65 and -66 - although that's odd because there's nothing obviously spice related.
Comment 10 Miroslav Rezanina 2014-10-24 12:03:56 UTC 
Fix included in qemu-kvm-1.5.3-77.el7
