xen上安装虚拟机:

一、全虚拟方式（hvm）安装

1、打开硬件支持：进入BIOS设置Configuratio >ntel Virtual Technology > Enabled。

2、创建映像 # 你希望在文件增长时才配置数据块，可以用迟缓的方式来配置 dd if=/dev/zero of=/etc/xen/Ubuntu.img oflag=direct bs=1M seek=20479 count=1 # 如果你想立即配置所有数据块，你亦可以这样做： dd if=/dev/zero of=/etc/xen/Ubuntu.img oflag=direct bs=1M count=20480

3、创建配置文件Ubuntu-hvm.cfg

builder='hvm' memory="4096" vcpus=4 name="ubuntu-16.10" vif = ['mac=00:16:3e:40:dd:11, bridge=br0']  disk=["file:/home/xiaojiatian/xen/img/ubuntu-16.10.img,hda,w","file:/home/xiaojiatian/ubuntu-16.10-server-amd64.iso,hdc:cdrom,r"] boot="dc" vnc=1 vnclisten="0.0.0.0" vncconsole=1

4、安装虚拟机

 

xm create /etc/xen/ubuntu-hvm.cfg vncviewer localhost:0

修改Ubuntu-hvm.cfg

 

builder='hvm' memory="4096" vcpus=4 name="ubuntu-16.10" vif = ['mac=00:16:3e:40:dd:11, bridge=br0']  #disk=["file:/home/xiaojiatian/xen/img/ubuntu-16.10.img,hda,w","file:/home/xiaojiatian/ubuntu-16.10-server-amd64.iso,hdc:cdrom,r"] disk=["file:/home/xiaojiatian/xen/img/ubuntu-16.10.img,hda,w"] #boot="dc" boot="c"  vnc=1 vnclisten="0.0.0.0" vncconsole=1

注意：

1、配置网桥

2、安装vnc，安装net-tools，安装netstat（查看vnc端口启动）

3、关闭防火墙 sudo systemctl stop firewalld.service、sudo systemctl disable firewalld.service

 

二、半虚拟方式（pv）安装

 

2、创建映像 # 你希望在文件增长时才配置数据块，可以用迟缓的方式来配置 dd if=/dev/zero of=/etc/xen/Ubuntu.img oflag=direct bs=1M seek=20479 count=1 # 如果你想立即配置所有数据块，你亦可以这样做： dd if=/dev/zero of=/etc/xen/Ubuntu.img oflag=direct bs=1M count=20480

3、创建配置文件Ubuntu-pv.cfg

 

choose an archive mirror https://launchpad.net/ubuntu/+archivemirrors

 

sudo mkdir -p /var/lib/xen/images/ubuntu-netboot cd /var/lib/xen/images/ubuntu-netboot sudo wget <mirror>/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/initrd.gz sudo wget <mirror>/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/vmlinuz

With a specific mirror chosen:

sudo mkdir -p /var/lib/xen/images/ubuntu-netboot cd /var/lib/xen/images/ubuntu-netboot sudo wget http://mirror.xtom.com.hk/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/vmlinuz sudo wget http://mirror.xtom.com.hk/ubuntu/dists/precise/main/installer-amd64/current/images/netboot/xen/initrd.gz

（PS：把Ubuntu镜像文件.iso挂载到/var/www/html上面）

name = "ubuntu-pv" memory = 1024 disk =['file:/home/xiaojiatian/xen/ubuntu-16.img,xvda,w'] vif = ['mac=00:16:3E:63:34:21,bridge=br0'] vcpus = 1 kernel = "/var/www/html/ubuntu/install/vmlinuz" ramdisk = "/var/www/html/ubuntu/install/netboot/ubuntu-installer/amd64/initrd.gz" extra = "debian-installer/exit/always_halt=true -- console=hvc0" #bootloader = "/usr/local/lib/xen/bin/pygrub"  #bootloader = "pygrub"

 

xl create -c ubuntu-pv.cfg

安装完成，关闭虚拟机。修改配置文件

ln -s /usr/lib/xen-4.1/bin/pygrub /usr/bin/pygrub

name = "ubuntu-16-pv" memory = 1024 disk =['file:/home/xiaojiatian/xen/ubuntu-16.img,xvda,w'] vif = ['mac=00:16:3E:63:34:21,bridge=br0'] vcpus = 1 #kernel = "/var/www/html/ubuntu/install/vmlinuz" #ramdisk = "/var/www/html/ubuntu/install/netboot/ubuntu-installer/amd64/initrd.gz" #extra = "debian-installer/exit/always_halt=true -- console=hvc0" #bootloader = "/usr/local/lib/xen/bin/pygrub"  bootloader = "pygrub"

xl create -c ubuntu-pv.cfg进入虚拟机

注意：

make dist PYTHON_PREFIX_ARG= make install PYTHON_PREFIX_ARG=

 

Try to find file libpython2.7.so.1.0: locate libpython2.7.so.1.0 In my case, it show out put: /opt/rh/python27/root/usr/lib64/libpython2.7.so.1.0 Then add dir /opt/rh/python27/root/usr/lib64 to file /etc/ld.so.conf And run ldconfig

pygrub启动失败，查看它的日志，报no module named xen.lowlevel.xc错误，可以修改pygrub，注释掉import xen.lowlevel.xc即可，详细参见https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=588811里面的解释。

pygrub启动失败，查看它的日志，报no module named fsimage错误，可以locate一下fsimage，看到它在/usr/local/lib64/python2.6/site-packages目录下，所以修改pygrub，在import fsimage前面添加sys.path = ['/usr/local/lib64/python2.6/site-packages'] + sys.path 即可，详细参见http://blog.csdn.net/jcwkyl/article/details/6324140里面的解释。
