History shows command I didn't run on my VPS (lemmy.ml)

Hey guys, I saw this in my VPS when checking history:

    1  chmod +x /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
    2  cat /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
    3  vi /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f

here is the content of the script:

# cat /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
swapoff /dev/vda2;mkswap /dev/vda2;swapon /dev/vda2;resize2fs /dev/vda1;yum -y update;systemctl disable guestfs-firstboot;reboot

This is a new server I provisioned on my VPS in racknerd. The command looks safe, but I'm wondering if these commands were executed on its own? Or someone has logged in to my VPS? This is also not normal, isn't it?

From the location of that script usr lib virt-sysprep looks to be a script put in the image by the provided to do a few things on first boot. Would have thought it was normal, but you can always ask them to double check

good point, it's just a test server for now so I'll try to reinstall OS and check if same commands will show in history
