One of the significant downside is that Qubes OS boots show and shutdowns slow.
I kind of understand why Qubes OS shutdowns slow - that is because Qubes OS want to shut down the remaining appVMs (what I do not understand is that why a VM using 10GB ram spends ~2 minutes shutting down, and ~5 minutes if it has 20GB ram; I suspect that the VM spends their time flushing the memory cache).
I does not understand why Qubes OS boots slow. Usually it takes more than 5 minutes to boot up. By pressing F1 I can see that Qubes OS spending nearly most of the booting time (when I looked at the
journalctl -r it seems to be around 4 minutes) playing with LVM (like it takes 4 minutes to “Finish LVM event activation on device ‘/dev/dm-0’”). btw I installed my Qubes OS on HDD.
I bet that the slow boot time can be one meme about Qubes OS. Every time why anyone asks why I like to “suspend” my computer I can only say that the OS boots as slow as a snail.
Anyone knows better about the question?
- Why is Qubes OS booting slow?
- Why is AppVM with large memory shutdowns show?
