[one-users] Dynamic attach CD to VM

[Daniel Dehennin]

Hello,

I'm trying to attach a CD to a running VM without success.

I saw that IDE hotplug does not work.

I found that we can predefine a  without source[1] but it does
not seems to work on 4.8.

How are you doing to attach CD on running VM?

Regards.

Re: [one-users] Sunstone comes up but nothing happens

[Daniel Molina]

Hi Steven,

Could you check if there is any error in the browser developer console?

Cheers

Re: [one-users] Bulk delete of vCenter VM's leaves stray VM's

[Javier Fontan]

The deletion code worked like this:

* Get the list of VMs
* Search the list of a VM with an specific UUID

When several VMs are being deleted it could happen that one VM marked for
deletion is in the list of all VMs but by the time it checks its UUID it is
already deleted. There is another patch for that problem [1] that you can
apply to fix it.

Still, we have made some other changes to deal with VMs and templates in
folders so I think it is better to use the version 4.10.1 that comes with
all these fixes.

Cheers

This limitation is there for legacy reasons, and because of your mail we
have decided to remove it in the next maintenance release [1].
Meanwhile, you can give USE permissions to the group through an ACL rule
[2].

In any case, please be aware that a persistent Image can only be used by 1
VM at a time.

Best regards.

Re: [one-users] error: internal error: protocol 'gluster' accepts only one host

[Javier Fontan]

Most probably you have more than one host defined in the parameter
"GLUSTER_HOST" from the gluster datastore.

The VM state cannot be changed easily. I think the safest way to fix your
problem would be to edit the driver to exit 0, and then "false-resume" your
VMs. This can be done with the following steps:

- In the front-end, edit the /var/lib/one/remotes/vmm//restore
file.
- To send the update file to each host, execute ''onehost sync --force".
- Then you can run "onevm resume" on the suspended VMs, and they should
move to the running state.
- After that, restore the original driver script and use the onehost sync
command again.
