Description
There was an issue reported that when using contextualization and CDROM images, the context iso always take precedence on the attached CDROM image and this prevents booting from it. A workaround what to set the target device for the CDROM to "hda". But this is supposed to be fixed in current version.
Now when trying a similar scenario but with an already existing VM by using the Attach feature, things do not work as expected.
When using a CDROM that has no target device set and attach this to a VM with a context iso then the CDROM will become hdb, not hda as expected.
Secondly, when attaching a CDROM that has the target device set to "hda" to a VM with a context issue the oned completely crashes and is restarted.
Both are undesired behaviours and should be fixed. I've tested this with ONE 4.14 on CentOS 7.

Hi Tim.
The issue about oned crashing is now fixed and in master and one-4.14 branches. You can safely apply the patch to your installation.
About the CDROM and context CD:- The CDROM always precede the context CD at instantiation, i.e. if both are part of the VM template. If there is no other CD, context will take hda.
- Booting from CD should not be an issue in this case.
- This cannot be change if you are attaching a CD to an existing VM with hda already taken by the context. Note that this would imply detaching the context iso, attaching the new one and re-attaching the context behind.
I'm closing this issue as fixed, if you have any other comment or issue please feel free to reply.
