You can review and change the name, description, and other general properties of a virtual machine.


Verify that the virtual machine is powered off.


  1. From the Navigator, select Compute > Virtual Machines.
  2. Select the virtual machine you want to edit.
  3. From the Card view, click the card for the virtual machine to open the Edit Properties panel.
  4. Click the Hardware menu, change the properties.



    Number of virtual CPUs

    The maximum number of virtual CPUs that you can assign to a virtual machine depends on the number of logical CPUs on the host and the type of guest operating system that is installed on the virtual machine.

    Cores per socket

    You configure how the virtual CPUs are assigned in terms of cores and cores per socket. Determine how many CPU cores you want in the virtual machine, then select the number of cores you want in each socket, depending on whether you want a single core CPU, dual-core CPU, tri-core CPU, and so on.

    Expose hardware-assisted CPU virtualization to guest OS

    You can expose full CPU virtualization to the guest operating system so that applications that require hardware virtualization can run on virtual machines without binary translation or paravirtualization.

    Total Memory

    The memory resource settings for a virtual machine determine how much of the host's memory is allocated to the virtual machine. The virtual hardware memory size determines how much memory is available to applications that run in the virtual machine. A virtual machine cannot benefit from more memory resources than its configured virtual hardware memory size.

    Memory hot add

    Memory hot add lets you add memory resources for a virtual machine while the machine is powered on. This feature is only supported on certain guest operating systems and virtual machine hardware versions.

    Virtual CPU hot add

    Virtual CPU hot add enables adding virtual CPUs to the virtual machine while it is powered on. You can add only multiples of the number of cores per socket. This feature is only supported on certain guest operating systems and virtual machine hardware versions.

    Number of sockets

    The number of sockets is determined by the number of virtual CPUs available.

    Removable Media

    Available removable media is displayed.

  5. In the Hard Disks field, click ADD to add a hard disk and fill out the following fields.
    Table 1. Hard Disk Options



    Bus Type

    Bus Number

    Unit Number

    Select a Hard disk size.

    The storage policy for the virtual machine is used. You can override this selection.

    Enter the bus type.

    Enter the bus number.

    Enter the unit number.

    By default, all the hard disks attached to a virtual machine use the storage policy specified for the virtual machine. You can override this default for any of these disks when you create a virtual machine or modify its properties. The Size field for each hard disk includes a drop-down menu that lists all the storage policies available to this virtual machine.

  6. In the NICs field, click ADD, and fill out the following fields. Virtual machine version 4 supports up to four NICs, and virtual machine versions 7, 8, 9, and 10 support up to ten NICs. vCloud Director supports modifying virtual machine NICs while the virtual machine is running. For information about supported network adapter types, see
    Table 2. NIC Options

    Primary NIC




    IP Mode

    IP Address

    MAC Address

    A flag displays when the primary NIC is selected.

    Select a primary NIC. The primary NIC setting determines the default and only gateway for the virtual machine. The virtual machine can use any NIC to connect to virtual and physical machines that are directly connected to the same network as the NIC, but it can only use the primary NIC to connect to machines on networks that require a gateway connection.

    Deselect the check box to disconnect a NIC.

    Select a network from the drop-down menu.

    Select an IP mode:

    • Static - IP Pool pulls IP addresses from the network's IP pool.

    • Static - Manual allows you to specify an IP address.

    • DHCP pulls IP addresses from a DHCP server.

    If you selected Static - Manual, type an IP address

    Enter the network interface MAC address.

  7. Click Save once you have completed making your changes.
