## VM images

## vGateway images extensions

* .qcow2 - KVM type Virtual Machines
* .vmdk - VMware and VirtualBox and ESXi
* .vdi - VirtualBox
* .vhdx - Microsoft Hyper-V
* .vhd  - Azure requires fixed size

## Example commands Convert qcow2 to other formats

### Convert for VirtualBox (.vdi)

```bash
qemu-img convert -O vdi ubuntu.qcow2 ubuntu.vdi
```

### Convert qcow2 to vmdk and make it VMware Workstation Player Compatible

```bash
qemu-img convert -f qcow2 -O vmdk ubuntu.qcow2 ubuntu.vmdk
```

### Convert qcow2 to vmdk and make it ESXi Compatible (doesn't work with VMware Workstation Player)

```bash
qemu-img convert -f qcow2 -O vmdk -o subformat=streamOptimized ubuntu.qcow2 ubuntu.vmdk
```

### Covert for ESXi 6 - Create a VMDK version 6 image (instead of version 4) (doesn't work with VMware Workstation Player)

```bash
qemu-img convert -f qcow2 -O vmdk -o adapter_type=lsilogic,subformat=streamOptimized,compat6 ubuntu.qcow2 ubuntu.vmdk
```

### Convert qcow2 to Microsoft Hyper-V new vhdx format

```bash
qemu-img convert -f qcow2 -O vhdx -o subformat=dynamic ubuntu.qcow2 ubuntu.vhdx
```

### For Azure (VHD images on Azure must have a virtual size aligned to 1 MB.)

* https://docs.microsoft.com/en-us/azure/virtual-machines/linux/create-upload-generic#resizing-vhds

```bash
# requires qemu 2.6+
qemu-img convert -o subformat=fixed,force_size -O vpc MyLinuxVM.qcow2 MyLinuxVM.vhd
```

## Example convert.sh script

    root@aws1-cm-01:~/temp# cat convert.sh

```bash
#!/bin/bash
echo "vGateway Name: "
read vgwname
echo "provide link:"
read link
curl $link > ${vgwname}.qcow2
echo "Converting..."
qemu-img convert \
 -f qcow2 \
 -O vmdk \
 -o subformat=streamOptimized \
 ${vgwname}.qcow2 ${vgwname}.vmdk
```
