Booting Solaris Dom0

Install or upgrade to at least build 75 of Solaris Express: Community Edition, or later.

• Depending on the upgrade/install method, a Solaris xVM entry in `/boot/grub/menu.lst` may have already been created. Check by running:

     # bootadm list-menu
  

  If no Solaris xVM entry appears, run the following command to create one:

     # bootadm -m upgrade
  

  It should create an entry in /boot/grub/menu.lst similar to this:

  #---------- ADDED BY BOOTADM - DO NOT EDIT ----------
  title Solaris xVM
  kernel$ /boot/$ISADIR/xen.gz
  module$ /platform/i86xpv/kernel/$ISADIR/unix /platform/i86xpv/kernel/$ISADIR/unix [*]
  module$ /platform/i86pc/$ISADIR/boot_archive
  #---------------------END BOOTADM--------------------
  

  When booting Solaris xVM, the kernel$ line must refer to the Xen hypervisor, and there must be two module$ lines. The first module$ line must list the path to unix twice, with any arguments (once again, represented by [*] in the example) at the end of the line. The second module$ line lists the path to the boot archive:

  To boot Solaris on Xen in 32-bit mode on a 64-bit capable system, the entry must be manually edited to remove all instances of $ISADIR:

  #---------- ADDED BY BOOTADM - DO NOT EDIT ----------
  title 32-bit Solaris xVM
  kernel /boot/xen.gz
  module /platform/i86xpv/kernel/unix /platform/i86xpv/kernel/unix [*]
  module /platform/i86pc/boot_archive
  #---------------------END BOOTADM--------------------
  

  To boot the xVM entry by default, run bootadm list-menu to find the entry number of the xVM entry, and then run:

     # bootadm set-menu default=<number>
  

• A simple test to determine if things look approximately correct is to run xm top. (This command provides details of running domains; you should just have a single one called Domain-0.)

   # xm top
