esxi remote mount
mounting vmfs over ssh on esxi system on a linux box
https://serverfault.com/questions/549858/rsync-over-ssh-to-esxi
why not mount esxi file systems on a third machine with sshfs and rsync support, like so:
#mount src esxi file system
sshfs root@aaa.bbb.ccc:/vmfs/volumes/ mnt/sshfs/
src="mnt/sshfs/"
vmd="Storage_vmfs5/vm1-data"
#mount dst esxi file system
sshfs root@xxx.yyy.zzz:/datastore-vms/ mnt/tmp/
dst="mnt/tmp/"
#copy vm files
rsync -av --progress --stats --delete --force "$src$vmd" "$dst"
#unmount
fusermount -u $src; fusermount -u $dst

cmake for building hercules Hyperion (version 4) for arm
https://hercules-390.github.io/html/CMake/index.html
Quick build info from above:
QUICK START: Build Hercules Using CMake
To build Hercules on your computer using CMake, you need the following software installed:-
CMake version 3.4 or better:
cmake --version. (CMake older than 3.4? See these instructions.) - A git client version 1.8.5.1 or better:
git --version. - A c compiler. Both gcc and clang have been tested.
- If you wish to use
1Stop-Cmake, sed. - A REXX interpreter,
either Regina Rexx or Open Object Rexx,
if you wish to run
make test, the CMake equivalent ofmake check. - Not required: autoconf, automake, flex, gawk, grep, m4, nor perl. Although there is no issue if these are installed on the system being used to build Hercules-390.
- Clone or update your local clone of Hyperion, as needed.
- Create a build directory and make that directory your current working directory. You can create the build directory anywhere you wish, so long as the directory is writable.
- Configure:
cmake <hyperion-source-dir> - Build:
cmake --build . - Run Tests:
ctest - Install:
cmake -P cmake_install.cmake(if you wish)
