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.

Reproduce this bug with qemu-kvm-common-1.5.3-14.el7.x86_64

host:
qemu-kvm-common-1.5.3-14.el7.x86_64
qemu-img-1.5.3-14.el7.x86_64
qemu-kvm-tools-1.5.3-14.el7.x86_64
libvirt-daemon-driver-qemu-1.1.1-12.el7.x86_64
qemu-kvm-1.5.3-14.el7.x86_64

steps:
1 List qemu-kvm device name.
 #/usr/libexec/qemu-kvm -device ?

2 Run following command line
 #/usr/libexec/qemu-kvm -device isa-vga -monitor stdio
 #/usr/libexec/qemu-kvm -device isa-cirrus-vga -monitor stdio

result:
1 Got following in device list.
name "isa-vga", bus ISA
name "isa-cirrus-vga", bus ISA

2 qemu-kvm accepted isa-vga and isa-cirrus-vga device.
# /usr/libexec/qemu-kvm -device isa-vga -monitor stdio
QEMU 1.5.3 monitor - type 'help' for more information
(qemu) VNC server running on `::1:5900'

# /usr/libexec/qemu-kvm -device isa-cirrus-vga -monitor stdio
QEMU 1.5.3 monitor - type 'help' for more information
(qemu) VNC server running on `::1:5900'



Verify this bug with qemu-kvm-1.5.3-14.el7.x86_64

steps same as reproduce.

result:
1 Not found isa-vga and isa-cirrus-vga in device list.

2 isa-vga and isa-cirrus-vga is rejected
# /usr/libexec/qemu-kvm -device isa-vga -monitor stdio
QEMU 1.5.3 monitor - type 'help' for more information
(qemu) qemu-kvm: -device isa-vga: Parameter 'driver' expects device type

# /usr/libexec/qemu-kvm -device isa-cirrus-vga -monitor stdio
QEMU 1.5.3 monitor - type 'help' for more information
(qemu) qemu-kvm: -device isa-cirrus-vga: Parameter 'driver' expects device type

so this bug has been fixed.
