When running Red Hat Enterprise Linux 6.0 as a guest virtual machine on a Red Hat Enterprise Linux 7 host, the GUI might not work correctly. To work around this problem, access the Red Hat Enterprise Linux 6.0 server over an SSH connection using a command line interface, or upgrade the server to a later version of Red Hat Enterprise Linux 6.

Can not access the GUi of rhel7

Description of problem:
Try to boot up a rhel7 guest with GUI in the rhel7 host, and the machine type is rhel6.0.0, the GUI can not be used(just GUI can not be used), can login with other tty and ping/ssh work well.

Version-Release number of selected component (if applicable):
# rpm -q qemu-kvm
qemu-kvm-1.5.3-21.el7.x86_64

Guest/host kernel
# uname -r
3.10.0-61.el7.x86_64


How reproducible:
100%

Steps to Reproduce:
1.Boot rhel7 guest with -M rhel6.0.0
# /usr/libexec/qemu-kvm  -cpu Penryn -enable-kvm -m 4096 -smp 4,sockets=1,cores=4,threads=1 -usb -device usb-tablet,id=input0 -name rhel7 -rtc base=localtime,clock=host,driftfix=slew -device ahci,id=ahci1 -drive file=/home/RHEL-7.0-20131127.1.qcow2_v3,if=none,id=drive-ahci,format=qcow2,aio=native,werror=stop,rerror=stop -device ide-drive,bus=ahci1.0,unit=0,drive=drive-ahci,id=sata-disk -device virtio-balloon-pci,id=balloon1 -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -monitor stdio -serial unix:/tmp/ttyS0,server,nowait -qmp tcp:0:4444,server,nowait -spice disable-ticketing,port=5930,seamless-migration=on -vga std  -M rhel6.0.0 -netdev tap,id=hostnet0,script=/etc/qemu-ifup,vhost=on -device virtio-net-pci,netdev=hostnet0,id=net0,mac=54:52:1a:23:0b:01


Actual results:
Guest stayed the screen as attachment, but can be ssh/ping and can login with other ttys, 

Expected results:
RHEL7 GUI can be used with rhel6.0.0 machine type

Additional info:

I test other newer machine types, all are ok:
rhel6.1.0
rhel6.2.0
rhel6.3.0
rhel6.4.0
rhel6.5.0
