Hi all,
There was a lot of sub-threads, so I figured it's helpful to start a
new thread with a summary so far. For context; I have a super simple
perl script that pretends to be an RA for the sake of debugging.
https://pastebin.com/9z314TaB
I've had variations log environment variables and confirmed that all
the variables in the direct call that work are in the crm_resource
triggered call. There are no selinux issues logged in audit.log and
selinux is permissive. The script logs the real and effective UID and
GID and it's the same in both instances. Calling other shell programs
(tested with 'hostname') run fine, this is specifically crm_resource ->
test RA -> virsh call.
I ran strace on the virsh call from inside my test script (changing
'virsh.good' to 'virsh.bad' between running directly and via
crm_resource. The strace runs made six files each time. Below are
pastebin links with the outputs of the six runs in one paste, but each
file's output is in it's own block (search for file: to see the
different file outputs)
Good/direct run of the test RA:

Bad/crm_resource triggered run of the test RA:
- https://pastebin.com/vBiLVejW
Still absolutely stumped.
bandini found the problem
https://serverfault.com/questions/1105733/virsh-command-hangs-when-script-runs-in-the-background
/usr/bin/setsid --wait /usr/bin/virsh list --all
That fixed it.
omg. I'm going to sleep. holy crap.
