|
|
Optimized for
|
The type of system for which the virtual machine is to be optimized. There are two options: Server, and Desktop, and the field is set to Server by default. Virtual machines optimized to act as servers have no sound card, use a cloned disk image and are not stateless. In contrast, virtual machines optimized to act as desktop machines do have a sound card, use an image (thin allocation) and are stateless.
|

Name
|
The name of virtual machine. Names must not contain any spaces, and must contain at least one character from A-Z or 0-9. The maximum length of a virtual machine name is 64 characters.

Stateless
|
Select this check box if the virtual machine is to run in stateless mode. The stateless mode is used primarily for desktop virtual machines. Running a stateless desktop or server creates a new COW layer on the virtual machine hard disk image where new and changed data is stored. Shutting down the stateless virtual machine deletes the new COW layer, returning the virtual machine to its original state. This type of virtual machine is useful when creating virtual machines that need to be used for a short time, or by temporary staff.
|
|
Start in Pause Mode
|
Select this check box to always start the VM in pause mode. This option is suitable for virtual machines which require a long time to establish a SPICE connection, for example virtual machines in remote locations.
|
|
Delete Protection
|
Select this check box to make deletion of the virtual machine impossible. It is possible to delete the virtual machine only when this check box is not selected.

At the bottom of the General tab is a drop-down box that allows you to assign network interfaces to the new virtual machine. Use the plus and minus buttons to add or remove additional network interfaces.
