I am using libvirt 3.6 version on Ubuntu 17.10 and create domain with command:
virt-install --name dc02 --memory 1024,maxmemory=2048 --vcpus 1 --cpu host --boot uefi,hd,network --disk /var/lib/libvirt/images/dc02.qcow2,bus=virtio --network bridge=br.27,model=virtio --video=qxl --memballoon virtio --hvm --controller usb3 --machine=q35 --graphics spice,listen=192.168.69.108
Domain boot failed with BSOD message "Unaccesible boot device", but when i change virtio-drive to sata-drive, its successfuly bootvirt-install --name dc02 --memory 1024,maxmemory=2048 --vcpus 1 --cpu host --boot uefi,hd,network --disk /var/lib/libvirt/images/dc02.qcow2,bus=virtio --network bridge=br.27,model=virtio --video=qxl --memballoon virtio --hvm --controller usb3 --machine=q35 --graphics spice,listen=192.168.69.108
ps -ef output for virtio-drive look like:
