RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
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
