Description Guo, Zhiyi 2017-06-12 02:49:20 EDT
Description of problem:
Display 2 should be dropped when guest reboot

Version-Release number of selected component (if applicable):
qemu-kvm-rhev-2.9.0-9.el7.x86_64 
kernel 3.10.0-679.el7.x86_64(host & guest)

How reproducible:
100%

Steps to Reproduce:
1.Boot rhel7.4 guest with cli:
/usr/libexec/qemu-kvm -name rhel-sp4 -m 4G -machine pc,accel=kvm\
        -S \
        -cpu Skylake-Client,check,enforce \
        -smp 2 \
        -monitor stdio \
        -qmp tcp:0:4444,server,nowait \
        -device virtio-vga,max_outputs=2 \
        -serial unix:/tmp/console,server,nowait \
        -drive file=rhelsp4.qcow2,if=none,id=drive-scsi-disk0,format=qcow2,cache=none,werror=stop,rerror=stop -device virtio-scsi-pci,id=scsi0,addr=04 -device scs
i-hd,drive=drive-scsi-disk0,bus=scsi0.0,scsi-id=0,lun=0,id=scsi-disk0,bootindex=1 \
        -netdev tap,id=idinWyYp,vhost=on -device virtio-net-pci,mac=42:ce:a9:d2:4d:d7,id=idlbq7eA,netdev=idinWyYp \
        -spice port=3003,disable-ticketing,agent-mouse=on \
        -device virtio-serial-pci -chardev spicevmc,id=vdagent,debug=0,name=vdagent \
        -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 \
2.Enable Display 2 from remote viewer: View -> Displays, and enable Secondary display for Display 2 from geust display settings.
3.Reboot guest

Actual results:
Display 2 won't be dropped. After guest reboot finish and login to Desktop, Display 2 show "Waiting for display 2..." and won't get guest desktop graphic automatically. Need to uncheck and check Display 2 again to make it works normally

Expected results:
Display 2 should be dropped when guest reboot. Test against qxl-vga, Display 2 will be dropped and I think it is reasonable to drop display 2 if it cannot get guest desktop graphic automatically
