virtualbox.org

Hi,

I'm working on a VirtualBox driver for Cloudify: (virtualbox-cloudify-driver in github)
Cloudify is a tool to deploy your application on any IaaS.
Because I don't have an internet connection sometimes, I decided to develop this driver to simulate a cloud on my laptop.
It works fine, I'm using the WebService to do that, with the vboxjws.jar.

In Cloudify 2.5, you can now attach a "volume" to the VM. Ex: in EC2, you can attach an EBS to the VM, so when the VM crash, it creates a new VM and attach the EBS to it.

I started to implement this feature in my driver, but it's not working:
I saw that "storageattach" can attach (or detach) volumes to a running VM if it uses a SATA controller, but the WebService API doesn't allow me to do that (exception about "the state of the VM is running")

Is it a "feature request" ? How can I ask that ? Can I change it "quickly" by contributing to the vboxjw.jar (so you can merge my contribution latter) ? If so, do you have any hints?

Thanks by advance.
Regards.

Are you positive the VM still has free SATA port available before attempting the attach?

Yes I'm sure (I already had this error before, now I put the maximum number of port: 30)

My error log is:

Code: Select all

2013-04-15 20:18:28,804 ESM SEVERE [org.openspaces.grid.gsm.machines.plugins.NonBlockingElasticMachineProvisioningAdapter] - Unexpected exception:VirtualBox error: The machine is not mutable (state is Running) (0x80BB0002); Caused by: org.virtualbox_4_2.VBoxException: VirtualBox error: The machine is not mutable (state is Running) (0x80BB0002)
    at org.virtualbox_4_2.IMachine.attachDevice(IMachine.java:2818)

As you can see, the WebService doesn't allow me to "hot plug" the disk.

In the WebService output (vboxwebsrv) I have the same error:

Code: Select all

32:39:36.660812 SQW01    API return code:            0x80BB0002 (VBOX_E_INVALID_VM_STATE)

32:39:36.660877 SQW01    COM error info text:        The machine is not mutable (state is Running)

Do you actual get a mutable object before attempting this change?
Relevant part of your code would help here.

Thank you for your help!

Indeed, I forgot to use a mutable object (but I use mutable object somewhere lese in the code... really don't know this time I didn't).

So I changed:

Code: Select all

IMachine m = virtualBoxManager.getVBox().findMachine(machineGuid);
m.attachDevice(defaultController, controllerPort, 0, DeviceType.HardDisk, medium);

By:

Code: Select all

IMachine m = virtualBoxManager.getVBox().findMachine(machineGuid);
ISession session = virtualBoxManager.openMachineSession(m);
m = session.getMachine();

try {
    m.attachDevice(defaultController, controllerPort, 0, DeviceType.HardDisk, medium);
    
    m.saveSettings();
} finally{
    this.virtualBoxManager.closeMachineSession(session);
}

Can u tell me which programming laguage it is?

.jar == Java.
