Description of problem:


Version-Release number of selected component (if applicable):
# uname -r
2.6.18-194.el5
# rpm -q kvm
kvm-83-171.el5


How reproducible:
100%

Steps to Reproduce:
1.start guest:
# /usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -drive
file=rhel5.5-64-virtio.qcow2,media=disk,if=virtio,boot=on,cache=off,index=0,werror=stop
-smp 1 -m 1G -cpu qemu64,+sse2 -vnc :31 -monitor stdio -net
nic,vlan=0,macaddr=20:20:28:90:68:80,model=e1000 -net
tap,vlan=0,script=/etc/qemu-ifup -boot c -drive
file=test_read.qcow2,if=virtio,media=disk,werror=stop,readonly=on

2.
(qemu) eject ide1-cd0
(qemu) change ide1-cd0 gpxe.iso 
(qemu) info block

Actual results:
ide1-cd0: type=cdrom removable=1 locked=0 file=gpxe.iso ro=0 drv=raw  

Expected results:
ide1-cd0: type=cdrom removable=1 locked=0 file=gpxe.iso ro=1 drv=raw

Comment 3 Jiri Denemark 2010-10-22 13:14:05 UTC
Note, this is actually preventing the media to be changed at all using libvirt if selinux is in enforcing mode so this would probably deserve higher priority.

Comment 4 Dor Laor 2010-10-24 10:59:44 UTC
Markus, what's your view of it? Is it complex to fix?

Comment 7 RHEL Program Management 2011-01-11 20:52:32 UTC
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.

Comment 8 RHEL Program Management 2011-01-11 22:50:54 UTC
This request was erroneously denied for the current release of
Red Hat Enterprise Linux.  The error has been fixed and this
request has been re-proposed for the current release.

Comment 9 Markus Armbruster 2011-01-14 16:08:04 UTC
Probably related to rhel-6 bug 602026.

Comment 10 Jes Sorensen 2011-01-17 11:14:24 UTC
Move to Tier2 to match tier of 602026

Comment 11 Jes Sorensen 2011-01-17 13:15:01 UTC
Reassign to Christoph as he did the RHEL6 patch for this one.

Christoph, please take a quick look and apply the same RHEL5.7
triage rules to this one.

Thanks,
Jes

It's easily doable for RHEL5.7.  I've just posted the patch for review.
