But docker-machine ssh test0 works fine! Thanks! [I installed all with brew, but this package i had built]

It seems that the version of qemu-img Ubuntu 18.04 comes with requires the disk size passed in with the postfix of 'M' instead of 'MB'.

E.g.:

if stdout, stderr, err := cmdOutErr("qemu-img", "resize", d.diskPath(), fmt.Sprintf("+%dM", size)); err != nil {

Seems like we need a v0.1.1 binary built, with some matching lines in the README.md afterwards.

$ curl -L https://github.com/machine-drivers/docker-machine-driver-qemu/releases/download/v0.1.0/default.docker-machine-driver-qemu-$(uname -s)-$(uname -m) > docker-machine-driver-qemu
$ sudo cp docker-machine-driver-qemu /usr/local/bin/docker-machine-driver-qemu
$ sudo chmod 755 /usr/local/bin/docker-machine-driver-qemu

Not sure where that "default" came from last time, but we should probably try to get rid of it if we can ?

Will also fix #2

This driver works fine in Windows with Boot2docker but I can't get this working with Rancher. The example presented here uses cloud-config.yml but I have no idea about what to place in it and where this must be. Maybe that simply this cannot run in Windows?

The current release is out of date and does not contain an important bug fix #6 .

Please consider adding a CI file to automatically update the release. :-)

@SvenDowideit: This looks like exactly what I'm looking for to get qemu working with docker. How do you install? I assume make then make install? With that said, I tried and didn't have any success. :)

Make it work on windows also ? I tried it but got defeated by it . The main problem is the process not detaching properly , resulting in a blockage , otherwise it should work . Also modified some .network stuff to not throw errors anymore .

Do you think this is possible ? Thanks ...
