Folks, this is getting serious. My first open source (MIT license) project and I have no idea what I'm doing 😨

It's called nvirt. The concept in a nutshell: it's similar to writing/using a dockerfile, but for libvirt VMs.

Docs if you're curious to read more: https://nvirt-cli.gitlab.io/

I've just tagged v0.1.0 for testing, feedback and a bit more "tidy up" dev, especially before I commit to backwards compatibility for the "virtfile" format, but for anyone who's interested I'd appreciate feedback, ideas and/or rebukes (if I have wasted my time or committed any cardinal sins given I'm new to Go and actually publishing stuff...)

Huge shout-out for the #libguestfs and #virtManager projects - pretty sure I wouldn't have attempted something like this if those tools didn't exist.

Virt Tools의 홈페이지 대문에는 Linux 가상화 생태계를 구성하는 요소들이 정리되어 있습니다. 정리 차원에서 해당 내용 AI번역(+약간 수정)했습니다.

제가 하나 더 추가하자면 Web UI를 담당하는 Cockpit이 있을 것 같습니다.

2/ The "mount file system in a guest VM and then make it available via 9pfs" idea[1] mentioned by tytso in that thread made me wonder if this is something #libguestfs could handle without to much trouble. But I'm not really familiar with how it works, so I might be totally mistaken…

Bug #759725 “The kernel is no longer readable by non-root users” : Bugs : linux package : Ubuntu

The mode of the latest kernel has changed so it is no longer readable by non-root users: -rw-r--r-- 1 root root 4336016 2010-10-17 01:37 /boot/vmlinuz-2.6.35-22-generic -rw-r--r-- 1 root root 4336912 2010-11-24 12:46 /boot/vmlinuz-2.6.35-23-generic -rw-r--r-- 1 root root 4523072 2011-03-08 18:47 /boot/vmlinuz-2.6.38-6-generic -rw------- 1 root root 4523936 2011-04-11 05:24 /boot/vmlinuz-2.6.38-8-generic This prevents people from using this kernel to boot qemu virtual machines as non-root. ...
