Subject Setting user data removes SSH public key data on a running VM
Date Fri, 11 Oct 2013 08:31:56 GMT
Hi all,

My Environment is: CS 4.1.1, KVM hypervisor

Here is the use case steps:
1. Create SSH keypair "keypairname" through the REST API.
2. Deploy VM with the created keypair from step 1.
3. On the VM, the url "http://<dhcpserverip>/latest/public-keys" returns
the public key.
4. Update the running VM with userdata.
5. On the VM, the url "http://<dhcpserverip>/latest/public-keys" returns
nothing and the user data url "http://<dhcpserverip>/latest/user-data"
returns the user-data which was set in step 4.

Result: User data is set but public key is gone (cleaned).

When I update user data on a stopped VM, both SSH public key and user data
are available.

Is this behavior expected or is this some kind of an issue ?

Best regards,
Stanislav Petrov
