guestfish修改镜像内容

Posted 2020-10-08 波神

1、安装guestfish

yum install libguestfs-tools

注意，如果要修改windows镜像需要安装

yum install libguestfs-winsupport

2、修改配置文件：/etc/libvirt/qemu.conf

user = "root"

# The group for QEMU processes run by the system instance. It can be
# specified in a similar way to user.
group = "root"

将user和group前面的#号放开

然后重启：

systemctl start libvirtd

3、修改文件内容

以下示例是将镜像里面的/opt/scalarizr/embedded/lib/python2.7/site-packages/scalarizr-3.3.4-py2.7.egg/scalarizr/storage2/volumes/cinder.py

的233行里面的display_description改成description

guestfish -a redhat6.7-kvm-oracle11g-22disk-pulsar2.2.qcow2 -i sh "sed -i ‘233s/display_description/description/‘ /opt/scalarizr/embedded/lib/python2.7/site-packages/scalarizr-3.3.4-py2.7.egg/scalarizr/storage2/volumes/cinder.py"

注意，不使用-i参数的话，需要在交互shell中运行
