==================================
虚拟机创建在 /dev/xenLVg1/vm101_img 里面
虚拟机的配置文件在/home/xen/vm101/vm101.cfg
/home/xen/vm101/ 下还有ifcfg-eth0，以及mnt文件夹
手动启动虚拟机：
xm create /home/xen/vm101/vm101.cfg
错误：
Error: Kernel image does not exist: /boot/solus-vmlinuz
还需要：
All set! needed to run: php /usr/local/solusvm/includes/xenkernel.php
===================================================
php /usr/local/solusvm/includes/xenkernel.php
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/dbase.so' - /usr/lib/php/modules/dbase.so: cannot open shared object file: No such file or directory in Unknown on line 0

Modulefile is /etc/modprobe.conf

Kernel setup completed.
================================================================================
在solusvm里 Boot 虚拟机就可以了。
无法远程 ssh
进入 console 查看IP：
系统启动不起来
ERROR opening /dev/console: No such file or directory
Trying to use fd 0 instead.
WARNING: can't access (null)
exec of init ((null)) failed!!!: Bad address
Kernel panic - not syncing: Attempted to kill init!
查看vm101.cfg
===========================
less vm101.cfg
kernel = '/boot/solus-vmlinuz'
ramdisk = '/boot/solus-initrd.img'
#bootloader = '/usr/bin/pygrub'
extra = ''
memory = 512

vm101.cfg (END)
=========================================================================
看到一个问题，0 字节的template
到 slave 的/home/solusvm/xen/template 看到与maste同名的系统 CentOS-XX.tar.gz 为0字节
手动下载，改为与maste同名。
在solusvm面板中重装系统试试。
console 可以连得上了。
远程依然不行。
在console 中看到 IP是正确绑定的。
在xen的主机，即slave查看IP信息
