[Qemu-devel] [Bug 1285505] Re: [ppa 2.0~git-20140225] SIGABRT with -virtfs

[Thomas Huth <1285505@bugs.launchpad.net>]

If I get the last two comments right, the problem was only about the
Ubuntu PPA package, so I'm closing this for upstream QEMU, too. If you
still have problems with upstream QEMU here, please feel free to open
the ticket again.

Title:
  [ppa 2.0~git-20140225] SIGABRT with -virtfs

Status in QEMU:
  Invalid
Status in qemu package in Ubuntu:
  Fix Released

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:
