Comment 2 for bug 1738283

Should have mention I use openSUSE Leap 42.3 with above mentioned virtualization repo.

Removed the 0026-Fix-tigervnc-long-press-issue patch and rebuilt QEMU but no change.

But I noticed that if I run the ISO via libvirt and connect to it via virt-manager (virt-manager-1.4.1-4.1.noarch), the keys are there as expected:

/usr/bin/qemu-system-x86_64 -machine accel=kvm -name guest=OI,debug-threads=on -S -object secret,id=masterKey0,format=raw,file=/var/lib/libvirt/qemu/domain-2-OI/master-key.aes -machine pc-i440fx-2.11,accel=kvm,usb=off,vmport=off,dump-guest-core=off -cpu kvm64 -m 2048 -realtime mlock=off -smp 1,sockets=1,cores=1,threads=1 -uuid 5664149e-26ad-4ee8-8170-16701f107b4b -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/domain-2-OI/monitor.sock,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime,driftfix=slew -global kvm-pit.lost_tick_policy=delay -no-hpet -no-shutdown -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 -boot strict=on -device ich9-usb-ehci1,id=usb,bus=pci.0,addr=0x3.0x7 -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pci.0,multifunction=on,addr=0x3 -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pci.0,addr=0x3.0x1 -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pci.0,addr=0x3.0x2 -drive file=/var/lib/libvirt/images/OI-hipster-minimal-20171031.iso,format=raw,if=none,id=drive-ide0-0-0,readonly=on -device ide-cd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -vnc 127.0.0.1:0 -device VGA,id=video0,vgamem_mb=16,bus=pci.0,addr=0x2 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 -msg timestamp=on

Connection via TigerVNC (tigervnc-1.6.0-21.1.x86_64) to the same VM is unable to write those characters.
