在此答案中:在线是否有任何预构建的QEMU Ubuntu映像(32位)?我已经描述了Ubuntu 18.04 guest / host的以下工作设置:
- 云映像arm64:最快的设置入门
- debootstrap arm64:相当快,但是可以进行更多图像定制
这些设置提供了预先构建的磁盘映像,并且不会通过安装程序。到目前为止,它们是我见过的最佳选择。
接下来,我还设法在QEMU上运行arm64服务器映像。但是,这将通过安装程序进行,这在边界上实在是不可行的,除非您不在使用KVM的ARM主机上。这特别麻烦,因为完成安装需要数十个交互。
这是在Ubuntu 18.10主机上测试过的服务器脚本:

# This is because the drivers for the default virtio are not installed in the ISO,
# because in the past it was not reliable on qemu-system-aarch64.
