Changes since v1.2.0:
!123 Update rust-vmm dependencies (main) ← (update-deps)
!121 implement std::error::Error trait (main) ← (fix-impl-error)
!120 Show the nofile hard limit value in the warning me... (main) ← (fix-rlimit-warn)
!119 Do not create tmpdir and bind mount /proc/self/fd ... (main) ← (remove-tmp-dir-for-proc)
!116 Disable killpriv_v2 by default (main) ← (no-killpriv-default)
The one that affected Kata Containers the most was !119, as virtiofsd
would get denied when SELinux was set to run on enforcing mode.
