[one-users] Booting stopped VMs a second time after an error cause problem with CDROM link

[Daniel Dehennin]

Hello,

On ONE 4.2, testing why the stop did not work[1]:

1. start a non persistent VM
2. stop it => successfully copied to frontend datastores/0
3. resume the VM, transfer failed => the VM state is back to STOPPED
4. fix the transfer problem[2]
5. resume the VM =>

    [TM][I]: Command execution fail: /var/lib/one/remotes/tm/ssh/context /var/lib/one/vms/1565/context.sh grichka:/var/lib/one//datastores/0/1565/disk.1 1565 0
    [TM][I]: context: Generating context block device at grichka:/var/lib/one//datastores/0/1565/disk.1
    [TM][E]: context: Command "ln -s /var/lib/one/datastores/0/1565/disk.1 /var/lib/one/datastores/0/1565/disk.1.iso" failed: ln: unable to create symlink “/var/lib/one/datastores/0/1565/disk.1.iso”: file exists
    [TM][E]: Error creating ISO symbolic link
    [TM][I]: ExitCode: 1
    [TM][E]: Error executing image transfer script: Error creating ISO symbolic link
    [DiM][I]: New VM state is FAILED

Maybe a clean should be done on host before resuming from STOPPED?

Regards.

Footnotes: 
[1]  each node must be able to SSH password-less to them self

[2]  was a host key verification failed
