Version-Release number of selected component (if applicable):
# uname -r 
# rpm -q kvm

How reproducible:

Steps to Reproduce:

CLI: /usr/libexec/qemu-kvm -no-hpet -no-kvm-pit-reinjection -usbdevice tablet -rtc-td-hack -startdate now -name win08R2 -smp 4 -m 8G -boot dc -net nic,vlan=0,macaddr=12:23:32:12:13:18,model=virtio -net tap,vlan=0,script=/etc/qemu-ifup -drive file=/dev/mike/win08R2,media=disk,if=virtio,cache=none,boot=on,format=raw,werror=stop -spice host=0,ic=on,port=5910,disable-ticketing -qxl 1 -cpu qemu64 -M rhel5.6.0 -notify all -balloon virtio -monitor stdio -uuid 4e8567a1-4f9a-40aa-89d4-6278dd6c26d5
2.start listenning port

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 3 RHEL Program Management 2011-01-11 22:56:09 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 4 Gerd Hoffmann 2011-01-12 10:53:25 UTC
Spice server does this intentionally, seems to be needed for the spice client migration (i.e. have the spice client switch over to the new host after migration automatically).  Changing this looks non-trivial and has a pretty high risk of introducing regressions.
