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.

qemu: panic device: check for invalid address type
qemu now checks for invalid address type for a panic device, which is
currently implemented only to use ISA address type, thus rejecting
any other options, except for leaving XML attributes blank, in that case,
defaults are used (this behaviour remains the same from earlier verions).

Description of problem: panic device only could specify isa type address with iobase(ioport). libvirt should forbid other address type for panic device in order to avoid confusion from users. Version-Release number of selected component (if applicable): libvirt-0.10.2-43.el6.x86_64 qemu-kvm-0.12.1.2-2.439.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1. add panic device to guest, which address is same with memballoon # virsh edit r7 ... <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </memballoon> <panic> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </panic> ... 2. start it # virsh start r7 Domain r7 started # ps -ef | grep qemu qemu 12136 1 13 02:26 ? 00:00:00 /usr/libexec/qemu-kvm -name r7 -S -M rhel6.6.0 -enable-kvm -m 1024 -realtime mlock=off -smp 1,sockets=1,cores=2,threads=1 -uuid 5a85c12d-6004-7c04-e2d2-55f723d977f4 -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/r7.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x5 -drive file=/var/lib/libvirt/images/r7.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x6,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,fd=22,id=hostnet0,vhost=on,vhostfd=23 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:07:f9:ca,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -device usb-tablet,id=input0 -vnc 127.0.0.1:0 -vga qxl -global qxl-vga.ram_size=67108864 -global qxl-vga.vram_size=67108864 -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x7 -device pvpanic -msg timestamp=on Expect result: in step 1, report an error.
