fedora18下的xen安装与管理

fedora18下的xen安装与管理

############################# xen installation ##############################

关闭防火墙和禁用selinux

# iptables -F

# service iptables save

# vim /etc/selinux/config

    SELINUXTYPE=permissive

xen的安装

# yum update

# yum -y install xen xen-hypervisor kernel-xen libvirt-daemon-xen virt-manager virt-viewer libvirt libvirt-pythonpython-virtinst libvirt-daemon-config-network libvirt-daemon-driver-network 

# yum -y install tigervnc

xen的默认启动(grub2)的配置

# GRUB_DEFAULT="saved"

# grub2-mkconfig -o /boot/grub2/grub.cfg

# grep ^menuentry /boot/grub2/grub.cfg | cut -d "'" -f2

xend服务的配置

# systemctl enable xend.service

# systemctl start xend.service

# systemctl status xend.service

xen-tools的安装

# yum -y install debootstrap perl-Text-Templateh perl-Config-IniFiles perl-File-Slurp perl-File-Which perl-Data-Dumper

# wget http://xen-tools.org/software/xen-tools/xen-tools-4.3.1.tar.gz

# tar zxvf xen-tools-4.3.1.tar.gz

# cd xen-tools-4.3.1

# make install

############################## xen configuration file ##############################

fedora18下，xen虚拟机的配置文件存放路径: /var/lib/xend/domains/"uuid"，镜像存放路径: /var/lib/xen/images/“virtual name”

rhel5.4下，xen虚拟机的配置文件存放路径: /etc/xen/“virtual name”，镜像存放路径: /var/lib/xen/images/“virtual name”

故需/var/lib/xend/domains/"uuid"内容转出到/etc/xen/“virtual name”下，实例“virtual name”为vm0{1..5}，总共5台虚拟机，故有以下的脚本

# vim fedora-xen-virt-manager.sh

    #!/bin/bash

    xenfile=/etc/xen/vm0{1..5}

    if [ -f $xenfile ]

    then

        rm -rf $xenfile

    if

    for i in vm0{1..5}

    do

        virsh dumpxml $i > /root/$i.xml

        cd /root

        virsh domxml-to-native xen-xm $i.xml > /etc/xen/$i

    done

############################## xen manage ##############################

# xm list

# xm create DomainName

# xm console DomainName

# xm destroy DomainName

# xm reboot DomainName

# xm shutdown DomainName

# xm pause DomainName

# xm unpause DomainName

# xm save DomainName

# xm restore DomainName

# xm rename DomainName

# virt-install -p -n vm01 -f /var/lib/xen/images/vm01.img -s 4 -r 512 --vcpus=2 -b br0 -l ftp://192.168.254.254/pub -x "ks=ftp://192.168.254.254/pub/ks.cfg"

# virt-clone -o vm01 -n vm02 -f /var/lib/xen/images/vm02.img

############################## xen network configuration ##############################

给vm01增加一块网卡

# vim /etc/xen/vm01

vif = [ "mac=00:16:36:88:76:d4,bridge=br0,script=vif-bridge","mac=00:16:36:77:66:d5,bridge=virbr0,script=vif-bridge" ]

# cp /etc/libvirt/qemu/networks/default.xml /etc/libvirt/qemu/networks/virbr1.xml

# vim /etc/libvirt/qemu/networks/virbr1.xml

<network>

  <name>virbr1</name>

  <uuid>703619d1-1b15-4621-acc6-6f2d88f51eb9</uuid>

  <bridge name="virbr1" />

  <forward/>

  <ip address="192.168.123.1" netmask="255.255.255.0">

    <dhcp>

      <range start="192.168.123.2" end="192.168.123.254" />

    </dhcp>

  </ip>

</network>

# ln -s /etc/libvirt/qemu/networks/virbr1.xml /etc/libvirt/qemu/networks/autostart/virbr1.xml

小结:    fedora18下，图形化下调用“虚拟系统管理器”是kvm；在xen下安装和配置虚拟机，还是得靠字符界面下操作，故写下此文，方便日后翻查。
