xVM Visual Panel

Visual Panel Introduction

Visual Panels is a development framework for Solaris system administration applications.  Applications created using this framework ("panels" for short) typically allow an end user to configure various pieces of a Solaris system.  These pieces can include desktop or system settings. For more information, see "Introduction to Visual Panels"  http://wikis.sun.com/display/vpdoc/Introduction+to+Visual+Panels.

Sun xVM Hypervisor Configuration 

The hypervisor configuration can be used to enable, disable and configure the hypervisor. See the xVM(5) man page for more details and terminology definitions.

The following topics are included:

• The Hypervisor Configuration: Basic Tab
  
• The Hypervisor Configuration: Advanced Tab
  

The Hypervisor Configuration: Basic Tab

The basic tab provides a checkbox that is used to configure whether the OpenSolaris OS should boot normally on hardware, or boot under the control of the hypervisor. 

Setting the "Enable Hypervisor" checkbox to true will update the grub(5) menu listing so that booting into the hypervisor is enabled. De-selecting the check box will update the menu listing so that Solaris is booted on hardware.

The tab also provides a menu used to control the amount of memory that should be reserved for domain 0. 

The "Reserved Memory" menu configures the GRUB menu item so that the specified amount of memory is reserved for use by domain 0. The default value is the lower of 1/2 of total installed memory, or 2048 MB.

The Hypervisor Configuration: Advanced Tab

The advanced tab provides configuration options that fine-tune certain commonly requested hypervisor startup options. 

The VCPU Limit option is used to limit the number of VCPUs that are available to domain 0. This value can be set as low as 0 (which is interpreted to mean no limit) or as high as the total available number of CPUs on the system. The default is 0.

The Pin VCPUs option causes the hypervisor to schedule VCPUs onto available CPUs. By default, VCPUs are not pinned to CPUs.

The hypervisor can be configured to boot with a Watchdog enabled, which will help to resolve certain failure situations.
