: Wrong bus type. vQFX expects virtio-blk , not sata . Fix : Ensure <target dev='vda' bus='virtio'/> .
Start the VM:
Running the virtual routing engine ( vqfx-20.2R1.10-re-qemu.qcow2 ) requires a dual-VM setup because the vQFX is split into a Routing Engine (RE) and a Packet Forwarding Engine (PFE) . To make it work, you must link these two separate QEMU virtual machines over a dedicated internal network. Core Components Required To get a functional switch, you need both images: RE Image: vqfx-20.2R1.10-re-qemu.qcow2 (the control plane). vqfx202r110reqemuqcow2 work
