Hi Sergio, The idea is interesting and I tried to launch a guest by your guide but seems failed to me. I tried both legacy and normal modes, but the vncviewer connected and told me that: The vm has no graphic display device. All the screen in vnc is just black.
kernel config: CONFIG_KVM_MMIO=y CONFIG_VIRTIO_MMIO=y I don't know if any specified kernel version/patch/config is needed or anything I missed. Could you kindly give some tips? Thanks very much. Jing
A QEMU instance with the microvm machine type can be invoked this way: - Normal mode: qemu-system-x86_64 -M microvm -m 512m -smp 2 \ -kernel vmlinux -append "console=hvc0 root=/dev/vda" \ -nodefaults -no-user-config \ -chardev pty,id=virtiocon0,server \ -device virtio-serial-device \ -device virtconsole,chardev=virtiocon0 \ -drive id=test,file=test.img,format=raw,if=none \ -device virtio-blk-device,drive=test \ -netdev tap,id=tap0,script=no,downscript=no \ -device virtio-net-device,netdev=tap0 - Legacy mode: qemu-system-x86_64 -M microvm,legacy -m 512m -smp 2 \ -kernel vmlinux -append "console=ttyS0 root=/dev/vda" \ -nodefaults -no-user-config \ -drive id=test,file=test.img,format=raw,if=none \ -device virtio-blk-device,drive=test \ -netdev tap,id=tap0,script=no,downscript=no \ -device virtio-net-device,netdev=tap0 \ -serial stdio
