Parameter 'driver' expects a driver name

[Sean McGuigan]

Hi

I'm running a fresh build of CentOS 6.6 running KVM with the latest version of Packer. Getting the following error but not sure if I should post to the KVM user group. Anyone seen this?

2014/12/16 21:04:28 packer-builder-qemu: 2014/12/16 21:04:28 Qemu stderr: qemu-kvm: -device virtio,netdev=user.0: Parameter 'driver' expects a driver name
2014/12/16 21:04:28 packer-builder-qemu: 2014/12/16 21:04:28 Qemu stderr: Try with argument '?' for a list.
2014/12/16 21:04:29 ui error: ==> ubuntu-1404-server: Error launching VM: Qemu failed to start. Please run with logs to get more info.

Hello,

It seems for that I did test that Packer-KVM/Qemu is more related to ubuntu and just works there.

I tried couple of times, and seems it's hardcoded for some binaries that are not available on redhat centos. I tried one kvm from rpmforge/epel but no joy..

Thanks for the info Alvaro, so I guess packer doesn't work on RHEL systems. Not really keen on Ubuntu as our production env run CentOS :(

[Alvaro Miranda Aguilera]

I haven't tested packer+kvm+OEL7, maybe there is more luck..

Crazy idea 1:

Create a VM with ubuntu, use packer+kvm there.. can be LXC.. I haven't tested but I have seen some guys doing kvm inside docker ..

Workaround not that crazy:

packer + virtualbox, do not install vbox additions, leave the source artifact, and once it finish, you can convert the vmdk disk to raw with either VBoxManage or qemu

and you can just use/boot that raw format disk

then you can use virtualbox-ovf to just install vboxadditions if you need it, and you reduce the number of gold images to manage.

Alvaro.

FYI: 

The version of qemu-kvm shipped with CentOS6 is quite old relative to that in the latest Ubuntu and building qcows2 images on Ubuntu results in images which cannot run on RDO. "image uses incompatible feature" or some such message when trying to instantiate on Icehouse + CentOS6.

[Ben Hines]

This driver error is fixed by using "net_device": "virtio_net_pci" with the latest packer from the git repository.
