使用 libvirt 启动 Codeready 容器导致 "format of backing image was not specified in the image metadata"
Starting Codeready Container with libvirt cause "format of backing image was not specified in the image metadata"
我正在尝试使用 CRC 在我的笔记本电脑上测试 Openshift 4 (Ubuntu 20)。 CRC 1.17 版不支持 Virtualbox 虚拟化,因此请按照设置说明进行操作
我正在使用 libvirt,但是当我使用 crc start
启动集群时,它会启动以下错误

我没有使用 libvirt 的经验,所以我坚持使用它,在网上我没有找到任何东西......
谢谢
crc_libvirt_4.5.14 图片有问题。修复它的最简单方法是执行
qemu-img rebase -f qcow2 -F qcow2 -b /home/${USER}/.crc/cache/crc_libvirt_4.5.14/crc.qcow2 /home/${USER}/.crc/machines/crc/crc.qcow2
现在,如果您尝试执行 crc start
,您将面临与 Apparmor 相关的“权限被拒绝”错误,除非您将主目录列入白名单。如果你不想修改 Apparmor 设置,/var/lib/libvirt/images
应该被列入白名单。将图像移动到那里:
sudo mv /home/${USER}/.crc/machines/crc/crc.qcow2 /var/lib/libvirt/images
然后编辑指向新映像位置的虚拟机设置:virsh edit crc
,然后将 <source file='/home/yourusername/.crc/machines/crc/crc.qcow2'/>
替换为 <source file='/var/lib/libvirt/images/crc.qcow2'/>
。
然后执行 crc start
然后...就是这样。
