hi, I have window 2012 instance running in Vmware ”vmdk”, how to make this vm compatible with openstack?. Do I need to install the VirtIO drivers before converting to qcow2? And if I need to install the VirtIO how to do it in window 2012 on pre-install windows VM?

It work with Windows server 2008. But with windows 2012 it did not work. look like installing the VirtIO driver in windows 2012 in not enough. Windows did not recognize the driver.

In Openstack controller, do below for to convert from vmdk to qcow2:

$ qemu-img convert -f vmdk -O qcow2 centos64.dsk centos64.qcow2

Not sure about VirtIO. Best way is to do above conversion and see you are able to launch the qcow2 image as VM.

I did convert it to qcow2, but when I upload the image it failed to boot and the kvm did not recognizance the hard disk. I think kvm need the virtio driver. But I don't know how to install it in existing VMware instance
