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:
boot a RHEL7.1 guest with "-chardev spicevmc", login the guest and reboot inside guest, qemu-kvm is Segmentation fault.

Version-Release number of selected component (if applicable):
qemu-kvm-rhev-0.12.1.2-2.448.el6.x86_64
kernel-2.6.32-515.el6.x86_64
spice-server-0.12.4-11.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot a rhel7.1 guest with "-chardev spicevmc"
# /usr/libexec/qemu-kvm -cpu Opteron_G1,enforce \
-enable-kvm  -m 4096  -smp 2,sockets=2,cores=1,threads=1,maxcpus=160 \
-monitor stdio \
-M rhel6.5.0 \
-numa node -numa node \
-global PIIX4_PM.disable_s3=0 \
-global PIIX4_PM.disable_s4=0 \
-drive file=/mnt/rhel_7_1_rhel6.qcow2,if=none,id=drive-scsi-disk,format=qcow2,cache=none,werror=stop,rerror=stop \
-device virtio-scsi-pci,id=scsi0,addr=0x13  \
-device scsi-hd,drive=drive-scsi-disk,bus=scsi0.0,id=data-disk2,bootindex=1 \
-netdev tap,id=hostnet0,vhost=on,id=hostnet0,script=/etc/qemu-ifup \
-device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=c2:9a:2f:9c:de:10,bus=pci.0,addr=0x5 \
-qmp tcp:0:4445,server,nowait \
-serial unix:/tmp/tty0,server,nowait \
-spice port=5901,password=redhat-vga,disable-ticketing -vga qxl \
-device virtio-serial-pci,id=virtio-serial1,bus=pci.0,addr=0x1a \
-chardev spicevmc,id=charchannel0,name=vdagent \
-device virtserialport,bus=virtio-serial1.0,nr=1,chardev=charchannel0,id=channel0,name=com.redhat.spice.0 \

2. login the guest
3. inside guest, do reboot
# reboot
