System Administration Commands                           xend(1M)



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 facil-
     ity, 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 service'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

System Administration Commands                           xend(1M)



         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 pass-
         word). 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  PRIVIRTMANAGE  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 regu-
         lar 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.

System Administration Commands                           xend(1M)



     config/xend-unix-server

         Controls whether the legacy HTP 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.
