This has a regression with virtfs. I created a simple cloud-image based VM with autopkgtest: $ sudo apt-get install autopkgtest $ adt-buildvm-ubuntu-cloud This part works fine with the new QEMU (it already boots the cloud- image in qemu and runs cloud-init). But running it with a shared 9p directory crashes: $ mkdir -p /tmp/shared $ qemu-system-x86_64 -enable-kvm -m 1024 -nographic -virtfs local,id=autopkgtest,path=/tmp/shared,security_model=none,mount_tag=myshare -snapshot adt-trusty-amd64-cloud.img ** ERROR:/build/buildd/qemu-2.0~git-20140225.aa0d1f4/qom/object.c:331:object_initialize_with_type: assertion failed: (type != NULL) Abgebrochen (Speicherabzug geschrieben) It should be easy enough to reproduce and the assertion message already should be clear, but this is the intersting part of the (unretraced) stack trace: #2 0x00007fe3329a9195 in g_assertion_message (domain=domain@entry=0x0, file=file@entry=0x7fe334c5a8e8 "/build/buildd/qemu-2.0~git-20140225.aa0d1f4/qom/object.c", line=line@entry=331, func=func@entry=0x7fe334c5ac40 "object_initialize_with_type", message=message@entry=0x7fe336e06e40 "assertion failed: (type != NULL)") at /build/buildd/glib2.0-2.39.90/./glib/gtestutils.c:2291 lstr = "331\000\377\177\000\000\320ޠF\377\177\000\000\220\026\321\066\343\177\000\000R\252\305\064\343\177\000" s = 0x7fe336e06e70 "pp\340\066\343\177" #3 0x00007fe3329a922a in g_assertion_message_expr (domain=0x0, file=0x7fe334c5a8e8 "/build/buildd/qemu-2.0~git-20140225.aa0d1f4/qom/object.c", line=331, func=0x7fe334c5ac40 "object_initialize_with_type", expr=<optimized out>) at /build/buildd/glib2.0-2.39.90/./glib/gtestutils.c:2306 s = 0x7fe336e06e40 "assertion failed: (type != NULL)" To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1285505/+subscriptions
