when i close qemu(using unfs style) with command "poweroff", There will be the following error. reproduce steps: 1, download kernel and rootfs tar ball 2, unpack tar ball 3, start qemu: runqemu kernel rootfs(directory) 4, shutdown system with command poweroff "bitbake meta-ide-support" build info: poky/branch: poky-contrib / stage/master_under_test commit id: 0ad72a18b5077c3c73ee9ee76ffcd700b14772cf images location : http://autobuilder.pokylinux.org/pub/nightly/20120510-2/machines/qemu/qemux86/bzImage-qemux86.bin http://autobuilder.pokylinux.org/pub/nightly/20120510-2/machines/qemu/qemux86/core-image-sato-qemux86.tar.bz2 detailed error info: build-sunyl@buildsunyl:~/work-dir/poky-contrib/test$ runqemu /home/build-sunyl/Downloads/bzImage-qemux86.bin qemux86/Assuming qemux86/ is an nfs rootfs Set MACHINE to [qemux86] based on kernel [/home/build-sunyl/Downloads/bzImage-qemux86.bin] Continuing with the following parameters: KERNEL: [/home/build-sunyl/Downloads/bzImage-qemux86.bin] ROOTFS: [qemux86/] FSTYPE: [nfs] Setting up tap interface under sudo Acquiring lockfile for tap0... runqemu-export-rootfs restart qemux86/ Stopping rpc.mountd Stopping rpc.nfsd Removing exports file Creating exports file...

Hi Sun, The only way I could see this occurring is if the runqemu scripts (specifically oe-find-native-sysroot) is unable to run bitbake. The directory you invoked this in when you ran into the problem, ~/work-dir/poky-contrib/test, was this your build directory?
Please provide more information and reopen if this hasn't been fixed...
