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 Radek Duda 2017-01-31 10:32:56 UTC
Description of problem:
If qemu-kvm command is launched with unspecified port option (e.g. "-spice port="), it starts normally.

Version-Release number of selected component (if applicable):
and qemu-kvm-rhev.2.6.0-28.el7.x86_64

How reproducible:

Steps to Reproduce:
1.Start VM with unspecified spice port ('-spice port=') for example:
/usr/libexec/qemu-kvm -machine pc  -nodefaults  -vga qxl   -device intel-hda,bus=pci.0,addr=03  -device hda-duplex -device virtio-serial-pci,id=virtio_serial_pci0,bus=pci.0,addr=04 -chardev spicevmc,id=idSwuYmk,name=vdagent -devicevirtserialport,id=idBWNLHY,name=com.redhat.spice.0,bus=virtio_serial_pci0.0,chardev=idSwuYmk -drive id=drive_image1,if=none,cache=none,format=qcow2,file=Rhel7.2 -device virtio-blk-pci,id=image1,drive=drive_image1,bootindex=0,bus=pci.0,addr=05 -m 1024 -spice disable-ticketing,port=  -monitor stdio

Actual results:
VM starts normally. 
(qemu) info spice -> No listening address specified

Expected results:
qemu-kvm will exit with code 1, and following message:
'neither port nor tls-port specified for spice' or something like this

Comment 2 Marc-Andre Lureau 2017-02-06 13:32:56 UTC
Sent one-liner  patch "[PATCH] qemu-option: reject empty number value", not sure it's really going to happen, foo= default to value 0 is perhaps an acceptable behaviour.
