Novell SUSE LINUX ENTERPRISE DESKTOP 11 SP1 - 8-18-2010 VIRTUALIZATION WITH ZEN Manual page 33

The user interface to the name of the virtual machine also offers the possibility
to add a description to the newly generated guest.
3 The Hardware page allows you to specify the amount of memory and number of
virtual processors for your virtual machine.
Initial Memory
The amount of memory initially allocated to the virtual machine (specified
in megabytes).
Maximum Memory
The largest amount of memory the virtual machine will ever need.
Virtual Processors
If desired, you can specify that the virtual machine has more virtual CPUs
than the number of physical CPUs. You can specify up to 32 virtual CPUs:
however, for best performance, the number of virtual processors should be
less than or equal to the number of physical processors.
4 Select the graphics mode to use:
No Graphics Support
The virtual machine operates like a server without a monitor. You can access
the operating system through operating system supported services, such as
SSH or VNC.
Paravirtualized Graphics Adapter
Requires that an appropriate graphics driver is installed in the operating
system.
5 A virtual machine must have at least one virtual disk. Virtual disks can be:
• File backed, which means that the virtual disk is a single image file on a
larger physical disk.
• A sparse image file, which means that the virtual disk is a single image file,
but the space is not preallocated.
• Configured from a block device, such as an entire disk, partition, or volume.
For more information about available physical storage, see Section 7.1,
"Mapping Physical Storage to Virtual Disks" (page 59).
