Terraform apply fails due to --synthcpu setting

[jzohrab]

Running the example with the provided ubuntu image fails:

2 error(s) occurred:
* virtualbox_vm.node.1: exit status 1
* virtualbox_vm.node.0: exit status 1

Setting Terraform tracing gives the output file with the following lines:

... [snip] ...
2016/01/12 11:43:43 [DEBUG] terraform-provider-virtualbox: pid-21335-vbm.go:45: executing: VBoxManage modifyvm node-01 ... [snip] ... --synthcpu off ...

synthcpu is no longer supported in VirtualBox 5. Docker also ran into this issue, ref https://github.com/docker/machine/pull/1496, and removed that flag.

This flag should be removed, and the code should use default VBoxManage flags as much as possible.

The code doesn't actually contain "synthcpu" ... checking further. ... update. After further checking, I wonder if the inclusion of Docker in the example image is what is causing trouble. Will try later with a different image.

This parameter stopped being supported on VirtualBox 5. Similar problems solved here ref, fix.

Found where it appears. CCLL is included by Gopfile.

Proposed a fix in https://github.com/ccll/go-virtualbox/pull/1. This will require a recompile of the provider.

Thanks @joaocc! I'd seen the Docker PR, but hadn't looked further. I hope @ccll can get to this, would be interested to try it out. Update: have emailed the project owner as some issues have been open for a while.

[joaocc]

Hi. Any news on this? Thx

[jzohrab]

Looks like this is a dead project, unless @ccll replies here.

[ccll]

Sorry for the late response, lately I've been occupied by other stuff, the PR is merged now.

[jzohrab]

Thanks @ccll for the response.
