debian10 制作动态扩容根分区镜像

标签：setting   netmask   libguest   virt   uri   board   tom   graphics   toc   

环境说明：centos 7 主机使用kvm创建openstack动态扩容根分区镜像。

安装kvm包

yum install -y qemu-kvm qemu-kvm-tools libvirt virt-manager virt-install libguestfs-tools

创建kvm网络环境

cat <<EOF | tee /etc/sysconfig/network-scripts/ifcfg-eth0 >> /dev/null
BOOTPROTO=static
DEVICE=eth0
ONBOOT=yes
BRIDGE=br0
NM_CONTROLLED=no
EOF

cat <<EOF | tee /etc/sysconfig/network-scripts/ifcfg-br0 >> /dev/null
TYPE=Bridge
BOOTPROTO=static
IPV4_FAILURE_FATAL=no
NAME=br0
DEVICE=br0
ONBOOT=yes
IPADDR=192.168.100.100
NETMASK=255.255.255.0
GATEWAY=192.168.100.2
DNS1=223.5.5.5
EOF

systemctl restart network

上传centos ISO镜像

自行上传镜像到宿主机上。本教程将镜像上传到 /opt/image 目录。

创建qcow2文件

mkdir /opt/images
qemu-img create -f qcow2 /opt/images/Debian-10.9.0-amd64.qcow2 10G

启动kvm虚机

systemctl start libvirtd
virt-install --virt-type kvm --name Debian10 --ram 1024 --cdrom=/opt/image/debian-10.9.0-amd64-DVD-1.iso --disk path=/opt/images/Debian-10.9.0-amd64.qcow2 --network bridge=br0 --graphics vnc,listen=0.0.0.0 --noautoconsole

安装系统自行决定怎么安装，分区最好手动分区。
安装好系统，是让 reboot 重启系统。重启后kvm虚拟机不会启动系统。需要手动启动系统。
