NAME

       xend - xVM control daemon

SYNOPSIS

       /usr/lib/xend

DESCRIPTION

       The xend daemon provides control of the Solaris xVM domains on a system. Its administrative interface is xm(1M).

   Service Management Facility Support
       The xend service is managed by the service management facility, smf(5), under the service identifier:

	 svc:/system/xvm/xend:default

       Administrative  actions	on  this  service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
       vice's status can be queried using the svcs(1) command.

   xend Properties
       The xend service instance has the properties listed below. These properties are administered by means of svccfg(1M) and svcadm(1M).

       config/default-nic

	   Specifies the default network interface used for guest domain networking. By default, the empty string is specified, in which case  the
	   first  interface  listed in the output of dladm(1M) show-link is used. If you need to use a different interface, for example, bge0, you
	   should change this property appropriately.

       config/dom0-cpus

	   The number of physical CPUs to be used for the virtual CPUs of the control domain (dom0). The default of 0 implies  that  each  virtual
	   CPU	will  be placed on its own physical CPU where possible. Note that physical CPUs can still be shared between dom0 and other domains
	   unless they are configured not to do so.

       config/dom0-min-mem

	   The minimum amount of memory guaranteed to the control domain (dom0). The default is 196 (MB).

       config/enable-dump

	   Controls whether a domain core dump should be created if a domain crashes. Dumps are generated in /var/xen/dump and	can  be  processed
	   with mdb(1). The default is true.

       config/vncpasswd

	   Sets  the  password	required  by any client connecting to a VNC session for a guest domain. Defaults to "" (no password). VNC password
	   authentication is not secure and should not be used for securing guest domain consoles.

       config/vnc-listen

	   Address to listen on for VNC connections. By default this is 127.0.0.1, which has a special meaning: only users or processes  with  the
	   PRIV_VIRT_MANAGE  privilege are allowed to connect, and they must be logged on locally. If you set this to any other value, then anyone
	   will be able to connect to VNC sessions, regardless of authorization.

       config/xend-relocation-address

	   Address that xend listens on for relocation requests. If blank or not present, all interfaces are used. The default is 127.0.0.1.

       config/xend-relocation-hosts-allow

	   A space-separated list of regular expressions. If the host name of a system matches any one of the given  regular  expressions,  it	is
	   allowed  to connect and interact with the relocation server, if the server has been enabled by the xend-relocation-server property. The
	   default is ^localhost$.

       config/xend-relocation-server

	   Controls whether the xend relocation server (for live migration) should listen for relocation requests on TCP port 8002. The default is
	   true.

       config/xend-unix-server

	   Controls whether the legacy HTTP server interface should be provided on the local machine. The default is true.

EXAMPLES

       Example 1 Modifying an Existing Property

       Use the following sequence of commands to modify an existing xend property.

	 # svccfg -s svc:/system/xvm/xend:default listprop
	 # svccfg -s svc:/system/xvm/xend:default setprop config/dom0-cpus = 1
	 # svcadm refresh svc:/system/xvm/xend:default

       Example 2 Enabling Live Migration

       By  default, xend listens only on the loopback address for requests from the localhost. If you want to allow other machines to live migrate
       to the local machine, you need to configure xend appropriately. For example:

	 # svccfg -s svc:system/xvm/xend
	 svc:/system/xvm/xend> setprop config/xend-relocation-address = ""
	 svc:/system/xvm/xend> setprop config/xend-relocation-hosts-allow = 
	 "^flax$ ^localhost$"
	 svc:/system/xvm/xend> end
	 # svcadm refresh svc:system/xvm/xend:default && 
	 svcadm restart svc:system/xvm/xend:default

FILES

       /var/log/xen/xend.log
       /var/log/xen/xend-debug.log

	   Log files for xend.

       /var/xen/dump/

	   Domain crash dump files.
