   I've changed Yocto parameters in tools/labs/qemu/Makefile as follows:

   YOCTO_BASE=https://downloads.yoctoproject.org/releases/yocto/milestones/yocto-5.1_M3
   YOCTO_URL=$(YOCTO_BASE)/machines/qemu/qemu$(ARCH)/
   YOCTO_IMAGE=core-image-minimal-qemux86.rootfs-20240901114018.ext4

   Have you encounter this problem? I failed to setup loop device.

   root@ubuntu20:/linux/tools/labs# make boot
   mkdir /tmp/tmp.NXSxdjS8gJ
   sudo mount -t ext4 -o loop core-image-minimal-qemux86.rootfs-20240901114018.ext4 /tmp/tmp.NXSxdjS8gJ
   mount: /tmp/tmp.NXSxdjS8gJ: failed to setup loop device for /linux/tools/labs/core-image-minimal-qemux86.rootfs-20240901114018.ext4.
   make: *** [qemu/Makefile:57: .modinst] Error 32

   Same happens after a fresh reboot?

   after reboot the system, it seems working. But I don't know if it's correctly booted up. I use minicom -D serial.pts to connect, but I can't log in to the booted vm.

   If you don't have any virt accelerator enabled (e.g kvm) then the boot should take around 1 minute.

   I think you can run something like this KVM=yes ; make boot

   Thanks for your reply. I try launching using KVM=yes ; make boot and wait for around 3mins, but still minicom shows nothing. I suspect this is because the arbritary env I set to DISPLAY=0?

   I know this was already answered, but here is a slightly different version that works:
   open file /linux/tools/labs/qemu/Makefile, and modify YOCTO_URL to:

   YOCTO_URL = http://downloads.yoctoproject.org/releases/yocto/yocto-4.0/machines/qemu/qemu$(ARCH)/
