i now was able to catch the error.
It is:
Length mismatch: 0000:00:12.0/virtio-net-pci.rom: 40000 in != 10000

This is a bug of your distribution. The file sizes for ROMs should
never change. In particular, if you round the sizes up to the next
power of 2 you should always have:
128k for bios.bin
256k for bios-256k.bin
64k for pxe-*.rom
256k for efi-*.rom
64k for vgabios-*
Unfortunately, most distribution get pxe-*.rom sizes wrong, because at
some point iPXE grew more features and didn't fit in 64k anymore with
the default configuration. I know at least Fedora does.
The solution is to copy the binaries from the QEMU git repository
(directory pc-bios/) to /usr/share/qemu.
