本文介绍如何在OpenSolaris上安装Xen更新，并详细解释了如何通过修改/boot/grub/menu.lst文件来设置默认启动项指向Xen，确保正确创建设备。此外，还提供了在Xen环境下运行Solaris所需的内核和模块配置示例。

Install the OpenSolaris Xen Update (July 2007) .

Adjust the default boot item in /boot/grub/menu.lst to point to the Xen line. You need to boot xen first in order to get the right devices created and reboot.

When booting Solaris on Xen, 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:
```
#---------- ADDED BY BOOTADM - DO NOT EDIT ---------- 
title Solaris on Xen kernel$ /boot/$ISADIR/xen.gz 
module$ /platform/i86xpv/kernel/$ISADIR/unix /platform/i86xpv/kernel/$ISADIR/unix [*] 
module$ /platform/i86pc/$ISADIR/boot_archive 
#---------------------END BOOTADM--------------------
```
To boot Solaris on Xen in 32-bit mode on a 64-bit capable system, all instances of $ISADIR must be removed:
```
#---------- ADDED BY BOOTADM - DO NOT EDIT ---------- 
title 32-bit Solaris on Xen kernel /boot/xen.gz 
module /platform/i86xpv/kernel/unix /platform/i86xpv/kernel/unix [*] 
module /platform/i86pc/boot_archive 
#---------------------END BOOTADM--------------------
```

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

NOTE: By default, you reboot into bare metal after install. If you subsequently reboot into dom0, you might need to manually enable all xctl services.

In Solaris, all of the properties from xend-config.sxp have been put into SMF xctl/xend (config/*).

To modify an existing property:

	# svccfg -s xctl/xend listprop 	
	# svccfg -s xctl/xend setprop config/dom0-cpus = 1 	
	# svcadm refresh xctl/xend

To create a new property.

	# svccfg -s xctl/xend setprop config/vncpasswd = astring: /"password/" 	
	# svcadm refresh xctl/xend 	
	# svcadm restart xend 	
	# svcprop xctl/xend

To enable the Xen services running on the system:

Become superuser, or assume the Primary Administrator role..

Verify that the xctl services are running.

# svcs -a | grep xctl

If the system displays the following, the services are not running:

disabled       12:29:34 svc:/system/xctl/console:default 
disabled       12:29:34 svc:/system/xctl/xend:default 
disabled       12:29:34 svc:/system/xctl/store:default

If the services are not running, verify that you booted an i86xpv kernel.
```
# uname -i i86xpv
```
Reboot if necessary.
If the correct kernel is running, enable the services.
```
# svcadm enable xctl/store 
# svcadm enable xctl/xend 
# svcadm enable xctl/console
```
You are now ready to create guest domains (domUs).
