Description of problem:
 qemu-kvm should examine the port already in use

Version-Release number of selected component (if applicable):
kernel:2.6.18-300.el5
kvm-83-246.el5


How reproducible:
100%

Steps to Reproduce:
1.boot  guest use the spice port as same as the incoming port

/usr/libexec/qemu-kvm -m 4096 -smp 2,cores=2,threads=1,sockets=2 -name win2008 -usbdevice tablet -rtc-td-hack -uuid 123465d2-2032-848d-bda0-de7adb149048 -boot dc -drive file=/mnt/win2008-64.qcow2,if=virtio,boot=on,bus=0,unit=0,format=qcow2,cache=none,boot=on,werror=stop -net nic,macaddr=54:52:00:23:1f:25,vlan=0,model=virtio -net tap,vlan=0,script=/etc/qemu-ifup -balloon none -monitor stdio -spice host=0,ic=on,port=5911,disable-ticketing -qxl 1  -fda /usr/share/virtio-win/virtio-drivers.vfd -drive file=/mnt/en_windows_server_2008_datacenter_enterprise_standard_sp2_checked_build_x86_dvd_342434.iso,media=cdrom,if=ide -incoming tcp:0:5911

Actual results:
 boot normally

Expected results:
should give a friendly tip for example:
(qemu) Migration failed. Exit code tcp:0:5955(-98), exiting.

It seems similar in nature to bug #682227.

Reassigning to better-fitting componets & assignees.
Comment 2 David Jaša 2011-12-07 16:18:57 UTC 
Tried to reproduce on rhel 6, it fails nicely as it should:

$ /usr/libexec/qemu-kvm -incoming tcp:0:1234 -spice port=1234 /dev/zero ; echo "qemu-kvm return code: $?"
do_spice_init: starting 0.8.3

spice_server_add_interface: SPICE_INTERFACE_KEYBOARD
spice_server_add_interface: SPICE_INTERFACE_MOUSE
spice_server_add_interface: SPICE_INTERFACE_QXL
red_worker_main: begin
Migration failed. Exit code tcp:0:1234(-98), exiting.
qemu-kvm return code: 158

Note for Virt QE: the reproducer on 5.x can be simplified to this universal command line so you don't have to re-create reporter's setup:

/usr/libexec/qemu-kvm -nographic -incoming tcp:0:1234 -spice port=1234 /dev/zero
