x86 also has this issue. upstream commit 777c5f1e436d334a57b650b6951c13d8d2799df0 Fix included in qemu-kvm-rhev-2.10.0-17.el7 Test against qemu-kvm-rhev-2.10.0-17.el7.x86_64 Use qemu cli: /usr/libexec/qemu-kvm -name EPYC -m 8G \ -cpu EPYC,enforce \ -smp 4,cores=2 \ -device VGA \ -device virtio-vga \ -uuid 215e11b2-a869-41b5-91cd-6a32a907be7e \ -device ich9-usb-uhci6 \ -drive file=/home/rhel75.qcow2,if=none,id=drive-scsi-disk0,format=qcow2,cache=none,werror=stop,rerror=sto p -device ide-drive,drive=drive-scsi-disk0 \ -qmp unix:/tmp/qmp,server,nowait \ -monitor stdio \ -vnc :0 \ -device usb-tablet \ -netdev tap,id=idinWyYp,vhost=on -device e1000,mac=42:ce:a9:d2:4e:d7,id=idlbq7eA,netdev=idinWyYp \ -serial unix:/tmp/console,server,nowait \ Boot rhel7.5 guest, guest can boot successfully and enter desktop, guest use VGA device as output Switch display to spice in qemu cli, guest also boot successfully and enter desktop, guest use VGA device as output too.
