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.

Does it mean that it also affects RHEL-6.4 and not just RHEL-7?

Comment 3 Amit Shah 2012-11-28 09:20:49 UTC 
Removing SDL was a deliberate choice, please don't re-enable it.

The orig. bug seems to be that -monitor stdio doesn't work.

Just RHEL-7 along. Hope RHEL7 behavors much closer RHEL not upstream.

Well, I've been able to fix it however I needed to remove the SDL from audio list too as it re-enabled SDL using the CONFIG_SDL=y again and it was failing. It took me some time to investigate however it's fixed in qemu-kvm-1.2.0-21.el7.

The package qemu-kvm-1.2.0-20.el7.x86_64 is too old, can not found it in brew.

Update to qemu-kvm-1.5.3-38.el7.x86_64 and test this bug.

Host:
RHEL-7.0-20131222.0
kernel-3.10.0-69.el7.x86_64
qemu-kvm-1.5.3-38.el7.x86_64

Steps:
/usr/libexec/qemu-kvm -monitor stdio

Result:
[root@amd-B95-8-1 ~]# /usr/libexec/qemu-kvm -monitor stdio
QEMU 1.5.3 monitor - type 'help' for more information
(qemu) VNC server running on `::1:5900'

(qemu) info vnc
Server:
     address: ::1:5900
        auth: none
Client: none
(qemu) info spice
Server: disabled
(qemu) 

The problem has gone, so this bug has been fixed.
