Bug Description

Binary package hint: qemu-kvm

kvm command fails with the below message when I try to use virtfs:

  kvm -kernel /boot/System.map-2.6.38-8-generic -initrd /boot/initrd.img-2.6.38-8-generic -virtfs local,path=./natty_root,mount_tag=hoge,security_model=none
  kvm: -virtfs local,path=./natty_root,mount_tag=hoge,security_model=none: there is no option group "virtfs"
  virtfs is not supported by this qemu build.

To enable virtfs, libattr1-dev package is required. The package should be listed in build dependency.

Thanks for taking the time to report this bug and helping to make Ubuntu better.

Thanks for the inf as well. I'll see if there's any problems when I add that to the dependencies.

The resulting package (for amd64) is available at http://people.canonical.com/~serge/qemu-with-virtio-debs.tgz. Would you like to test it before I push to the archive?

I've pushed the package for oneiric, which should build in awhile. I assume you'd like to see this SRUd to natty. Please feel free to do the SRU justification by editing the main description.

  * Add libattr1-dev to build-depends to enable use of 9p virtfs (LP: #782973)

Thanks Serge!

Well...I wanted to test your package though, unfortunately my machine had broken after I posted the report...so I cannot do, I'm very sorry.

However, I believe the fix would not harm because I actually rebuilt qemu-kvm package with libattr1-dev installed and it worked well.

I'm going to mark this Wontfix for natty until there is at least a specific request from someone who needs it. In order to fix it in natty, I would need to fill out a SRU justification, so it will help to be able to point to user demand, as well as to know that there will be someone around to test the fix.

I just started working with the SPICE interface and ran into this issue with the qemu-kvm-spice package on a 12.04 Precise Pangolin box. This is just another issue with that package in Precise.

@William,

please file a bug against qemu-kvm-spice (qemu-linaro) to get virtfs enabled there if it is not.
