qemu-system-x86: qemu doesn't show window with VM
Good Day All,
Problem description:
When I start qemu with the following command the VM seemingly gets
started but no window whatsoever shows up. AFAIR it always has worked
like that before.
$ qemu-system-x86_64 -m 1024M -name "Devuan GNU/Linux
Beowulf" -enable-kvm \
-vga cirrus -net nic -net user,hostfwd=tcp::1926-:22 -cdrom \
/mnt/somedir/devuan_beowulf_3.0.0_amd64_desktop-live.iso \
-boot menu=on &
$ qemu64 -m 1024M -name "eXe GNU/Linux" -enable-kvm -vga cirrus -net nic
\
-net
user,hostfwd=tcp::1921-:22 -cdrom /mnt/isodir/exegnu64_beowulf-20200707.iso
&
$ jobs

There is nothing in dmesg/syslog/messages/kern.log that indicates
something went wrong. There is only one message (per VM I think) which
says:
# kern.log
kernel: kvm [1608]: vcpu0, guest rIP: 0xffffffffbe25eb48 disabled
perfctr wrmsr: 0xc2 data 0xffff
After two hours of digging I neither can find a reason nor a report for
this behaviour on the net. Does anybody know what I might have missed
or how I can further troubleshoot?
Thanks for any hint.
Kind regards,
Stefan
