File types like .wic,.tar.bz2, .cpio are not supported. Since the error messages in these cases can be quite obscure for example wic gives: [ 10.009298] Kernel Offset: disabled [ 10.009298] ---[ end Kernel panic - not syncing: Invalid configuration from end user prevents continuing --- it would be helpful to validate the rootfs inputs. 72097 1 liezhi.yang 2017-04-05 09:03:43 +0000 The runqemu does check whether the fstype is supported or not: def check_arg_fstype(self, fst): """Check and set FSTYPE""" if fst not in self.fstypes + self.vmtypes: logger.warn("Maybe unsupported FSTYPE: %s" % fst) if not self.fstype or self.fstype == fst: if fst == 'ramfs': fst = 'cpio.gz' self.fstype = fst else: raise Exception("Conflicting: FSTYPE %s and %s" % (self.fstype, fst)) what did you mean about "validate the rootfs inputs.", please ? 72164 2 brian.avery 2017-04-06 20:59:08 +0000 Hmm, so maybe my understanding of what should and should not work is wrong. I built core-image-minimal for qemux86 off of master commitish 633ad6c9f436f5d2. The following works fine: runqemu tmp/deploy/images/qemux86/bzImage-qemux86.bin tmp/deploy/images/qemux86/core-image-minimal-qemux86.ext4 The following all fail in diverse ways: uvesa timeout, no login prompt: runqemu tmp/deploy/images/qemux86/bzImage-qemux86.bin tmp/deploy/images/qemux86/core-image-minimal-qemux86.cpio.gz runqemu tmp/deploy/images/qemux86/bzImage-qemux86.bin tmp/deploy/images/qemux86/core-image-minimal-qemux86.cpio No valid filesystem found, kernel panic: runqemu tmp/deploy/images/qemux86/bzImage-qemux86.bin tmp/deploy/images/qemux86/core-image-minimal-qemux86.tar.bz2 runqemu tmp/deploy/images/qemux86/bzImage-qemux86.bin tmp/deploy/images/qemux86/core-image-minimal-qemux86.wic Undefined video mode 318 (stays stuck for ~ 1 minute then actually booted after I came back from getting tea. I thought his was failing but apparently not...) $ runqemu qemux86 core-image-minimal wic ---- Does this help clarify? 75373 3 liezhi.yang 2017-07-28 07:15:04 +0000 Merged into master: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=5c7d025ced2120e4f277b8fb22813a8602e3f8c7
