Is it Dell Latitute by a chance? I have very similar problem on such
system, regardless of Qubes version: when it is on AC power, performance
is normal, but on battery it is significantly slower. Some workaround is
to change CPU scaling governor, by executing in dom0:

xenpm set-scaling-governor performance

The battery issue, btw, as far as I recall is nothing new in Qubes 4. It's not 
something specifc to your system, and if it gets fixed, it'll probably be an 
update to fix all the Qubes 4 systems out there. But maybe there are settings 
you can flip to fix it manually, however it's not something I've checked. 

Make sure the VM's that start at boot, are starting just as slow (or quick) as 
if you started them on an already running Qubes system. If the speed is 
similar, then at least you can assume it has nothing to do with the actual 
booting process. 

It sounds weird that it happens randomly, maybe a few more clues are needed to 
hunt down the actual reason as to why it happens, unless someone with better 
insight drops by.

After you type in your drive encryption password, followup by typing F1 key on 
your keyboard. This way you can follow the booting process in details as it 
happens. If any booting processes are hanging, you'll be able to take note 
"which one", and thereby narrow down the possible culprit. 

You can also do a "sudo journalctl --boot" or akin to that, after booting. But 
remember to do so after a fresh bootup, unless you want a mountain of extra 
unneeded information.

Also, if the booting is slow before you type in your drive encryption, then you 
know it's related to settings or features EFI/UEFI or Legacy-Boot/BIOS. It 
could also possibly be because you got a thumb-drive or external-harddrive 
sitting in your USB; which on some systems can make the booting process 
significantly slower as the system tries to identify bootable systems on the 
extra external-drives/thumb-drives.

Re: [qubes-users] Qubes 4.0 rc3 boot and performance is quite slow

2018-01-07 Thread Fabrizio Romano Genovese
Ok, I dug a bit deeper into this. It doesn't look like a problem of how much 
memory I give to VMs. Essentially, my QubesOS boots in two different ways:

- When QubesOS is happy, it starts in ~1 min (yup, starting up all the VMs 
still takes a while). The overall system is very reactive, for instance if I 
type qvm-ls I obtain some output straight away. Moreover, if I start a VM the 
notification "VM blabla is starting" is displayed immediately.

- When QubesOS is not happy, it starts in ~3mins. The overall system is very 
slow, qvm-ls takes 3-4 seconds to display output, and starting a VM takes up to 
20 seconds. Even the notification "VM blabla is starting" is displayed 4-5 
seconds after the command is issued. Moreover the battery is drained much much 
quicker (200% quicker give or take).

What makes Qubes happy or not happy to start seems to be completely random. I 
have a slight suspect that this may depend on booting the laptop while 
plugged/unplugged, but I cannot confirm this.
Essentially my Qubes experience atm can be exemplified as follows: "At boot, 
throw a coin. If it's heads then it's fine, otherwise it's fubar". Any 
suggestion (or report of similar behavior) would be greatly appreciated!

Fab

Can you try giving your VMs more initial memory?
I saw that the default of 400MB is causing VMs to swap like crazy on 
startup. I change it to 1000MB and stuff starts significantly faster.

I also removed swap in fstab on all templates, the only effect this has had 
so far is show that the memory balancer is in need of work. It fails to give 
hosts memory when they use significantly more than others.

[qubes-users] Qubes 4.0 rc3 boot and performance is quite slow

2018-01-04 Thread Fabrizio Romano Genovese
As the title says, Qubes 4.0rc3 boot is very slow compared to Qubes 3.2.

Looking at the console messages at startup, it looks like the problem is that 
Qubes takes more than one minute to boot sys-net, sys-firewall, sys-usb and 
sys-whonix. That was not the case in 3.2. 

Also, when giving 
qvm-start someVM
the startup time is again quite slow. Could it be that my VMs are based on 
Fedora26?

Cheers,
Fab
