Hi,

opennebula-5.3.90-1.x86\_64

I used to succesully run the following test setup with Vagrant

> <https://github.com/marcindulak/github-test-local/blob/master/vagrant-opennebula-tutorial-centos7.sh>

  
but for some time I’m getting the famous “Boot failed: not a bootable disk” from ttylinux.  
I found the following possible explanation of the boot failure “ttylinux is just for testing, it lacks virtio drivers and  
other amenities. Use hda for the disk and you should be fine.” [http://lists.opennebula.org/pipermail/users-opennebula.org/2013-November/042795.html](http://lists.opennebula.org/pipermail/users-opennebula.org/2013-November/042795.html)  
but in my case ttylinux seems to be already using hda.

Any suggestions how to correct the problem on the command line?

Can someone experienced look at that?  
What is the expected way to start ttylinux on the command line?  
Is it correct to specify `--prefix hd` for `oneimage create`?  
Is it correct that `onevm show` shows `hda` as the VM DISK number 0?  
Am I supposed to modify the context, which currently shows TARGET=“hdb” to TARGET=“hda”?

When trying to change the TARGET into hda in the context, starting from the state as in the above setup, I get:

```
[oneadmin@frontend ~]$ onevm recover --delete 0
[oneadmin@frontend ~]$ cat template.one
CONTEXT=[
  NETWORK="YES",
  SSH_PUBLIC_KEY="$USER[SSH_PUBLIC_KEY]",
  TARGET="hda" ]
CPU="1.0"
DISK=[

  LISTEN="0.0.0.0",
  TYPE="vnc" ]
MEMORY="127"
NIC=[
  NETWORK="private" ]
OS=[
  ARCH="x86_64" ]
VCPU="1"
[oneadmin@frontend ~]$ onetemplate update 0 template.one
[oneadmin@frontend ~]$ onetemplate instantiate ttylinux
[one.template.instantiate] Error allocating a new virtual machine template. Two disks have defined the same target hda
```

I’ll try to answer myself after comparing the working settings created using sunstone GUI to the CLI ones resulting in “Boot failed: not a bootable disk”.

> ```

apparently `--prefix vd --driver qcow2` are needed for ttylinux:

`oneimage create --name ttylinux --path http://marketplace.opennebula.systems/appliance/4fc76a938fb81d3517000003/download --datastore default --prefix vd --driver qcow2`

> ```

no, it should use vda.

> ```
> Am I supposed to modify the context, which currently shows TARGET="hdb" to TARGET="hda"?
>

with the above settings the context will have TARGET=“hda” set automatically.

A configuration that boots into ttylinux is shown below:
