Then you can create a new virtual machine and attach the vmdk image to it (see [http://techathlon.com/how-to-run-a-vmdk-file-in-oracle-virtualbox/ how to run a vmdk file in virtualbox] for detailed instructions on this). | Then you can create a new virtual machine and attach the vmdk image to it (see [http://techathlon.com/how-to-run-a-vmdk-file-in-oracle-virtualbox/ how to run a vmdk file in virtualbox] for detailed instructions on this). | ||

== Locking VMs == | |||
When working with multiple people in a project or simply to protect a VM from accidental deletion or shutdown it can be useful to lock it. | |||
To '''lock''' a VM, simply click on the "Lock Instance" from the action menu in the dashboard.<br/> | |||
Once a vm is locked most of the action menu item will not be able to be executed until the instance is unlocked. There is an icon indicating the lock state for every instance. | |||
To '''unlcok''' a VM, simply select the "Unlock Instance" from the action menu in the dashboard.<br/> | |||
==Resizing VMs== <!--T:59--> | |||
It is possible to resize a VM by changing its flavor. However, there are some things to be aware of when choosing to resize a VM which depends on whether you have a "p" flavor or a "c" flavor VM (see [[Virtual machine flavors]]). Resizing a VM may involve some risk as it is similar to deleting and recreating your VM with a new flavor, if in doubt contact cloud [[technical support]]. | It is possible to resize a VM by changing its flavor.

"c" flavors often have extra ephemeral drives, which will be resized when you choose a new "c" flavor. These ephemeral drives can not become smaller, and as such "c" flavor VMs can only be resized to flavors with equal or larger ephemeral drives. After the resize however, you will not immediately see a larger ephemeral drive within your VM (e.g. the [https://en.wikipedia.org/wiki/Df_(Unix) <code>df -h</code>] command will not show the size increase). To see this extra space you will need to resize your file system (see the [https://linux.die.net/man/8/resize2fs <code>resize2fs</code>] command). However, filesystem resizes should be treated with caution and can take considerable time if the partitions are large. Before resizing a filesystem it is recommend to create backups of its contents (see [[backing up your VM]]). | "c" flavors often have extra ephemeral drives, which will be resized when you choose a new "c" flavor.

Unlike "c" flavors, "p" flavors do not typically have extra ephemeral drives associated with them, so they can be resized to larger and smaller flavors. | Unlike "c" flavors, "p" flavors do not typically have extra ephemeral drives associated with them, so they can be resized to larger and smaller flavors. | ||
