I am using libvirt 3.6 version on Ubuntu 17.10 and create domain with command:

But when i run this domain with qemu-system its succsessfuly boot and work. Cmd looks like: qemu-system-x86_64 -machine type=pc-q35-2.8 -accel kvm -cpu host \ -cdrom /var/lib/libvirt/images/virtio-win-0.1.141.iso \ --bios /usr/share/OVMF/OVMF_CODE.fd \ -m 2048 -smp 2 -drive file=/var/lib/libvirt/images/dc02.qcow2,index=0,media=disk,if=virtio -boot menu=on \ -spice addr=192.168.69.108,port=5910,disable-ticketing

This adds lot of default devices that you can't see (qom-list qemu command could help with figuring out the differences), so maybe one of the devices along the way (controller) has a different model and is not working in the guest. Is it possible that the Windows guest was installed with the disk plugged in as SATA? Because just changing that doesn't really work for some Guest OSes and maybe QEMU emulates some older devices that work (just a very rough guess). For details about the differences I'd also try asking the QEMU people, just in case they miss it on this list.

I cannot fugire out where i went wrong
