Slow boot times

[jifitailu]

Hi,
I was making a VM of win10 (GPU Passthrough)
this tutorial https://www.youtube.com/watch?v=eTX10QlFJ6c
after fallowing tutorial vm works fine and no problem there but when rebooted the system I took too long I thought that is nothing and that is just applying settings but every time I try booting in the system I takes 5-4 min,
I typed

Code: Select all

systemd-analyze blame

here are results

Hi jifitailu. Perhaps you have an incorrect UUID in your /etc/fstab as described here:
viewtopic.php?p=1812371#p1812371
and here:
viewtopic.php?p=1540464#p1540464

Or the problem described here:
viewtopic.php?p=1725266#p1725266

Please post the output of cat /etc/fstab

Hello,
I agree with previous posts, but you've also a LVM (Logical Volume Management) issue. Perhaps that VM of yours doesn't work as smoothly as you expressed.
Maybe the output of

Code: Select all

systemd-analyze critical-chain

will give us a more precise idea of boot sequence.
