"fast-vm list" keep asking for sudo password

[jrjeon]

when runing fast-vm list, it errors with sudo password is required. Once, I run the command with sudo, then it stops asking.

$ fast-vm list
sudo: a password is required

# rpm -q fast-vm

Hi @jrjeon Jaram,

Thank you for reporting this issue. It seems as if something was missing from sudoers created by fast-vm during setup.

The request for sudo comes from this line - https://github.com/OndrejHome/fast-vm/blob/87f5a2e83d28059d6ff4ffb78b5b49919f47cc6c/fast-vm#L977

1. Would you be able to run following command on your system to check that it will ask for sudo password?

   # echo 'lvs'|LANG=C sudo -n /usr/libexec/fast-vm-helper.sh
   fastvm-pool 10.00g 0.00 private 

2. Can you check if you have following fast-vm-sudoers file present on your system?

   # cat /etc/sudoers.d/fast-vm-sudoers 
   ## fast-vm helper script
   %libvirt ALL=(root) NOPASSWD: /usr/libexec/fast-vm-helper.sh

3. For completeness could you please also provide me with following outputs?

   $ cat /etc/fast-vm.conf
   $ id
   $ id <your_user>

Thank you!

Hi Ondrej,

I apology for late update. it looks like there was some issue on sudo configuration, once I clean up the mess, I no longer sees error message. Thanks for the help.
