Title:
[ppa 2.0~git-20140225] SIGABRT with -virtfs
Status in QEMU:
New
Status in “qemu” package in Ubuntu:
Triaged
Bug description:
As requested on u-devel@, I tested QEMU
2.0~git-20140225.aa0d1f4-0ubuntu2 from ppa:ubuntu-virt/candidate. 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

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:
