"Cannot connect to qrexec agent for 60 .." - how to change this timeout?

[Oleg Artemiev]

Re all.

I've slow disk on my qubes PC. Sometimes when I start VMs it tells
that it can't connect to qrexec & fails to start automatically - I've
to start again manually & then on the second time the disk reads
faster due to cache & it succeeds. Where can I change the timeout to
90 seconds or even more?

$ qubes-prefs default_qrexec_timeout

You might want to increase default_shutdown_timeout as well, to
prevent your VMs from getting killed when they're slow to shut down.

Hi!

As I've been there, too (originally staring with an "USB stick" to run
Qubes OS, I found out that it's way too slow. Then I tried on external
USB-connected hardddisk, and it still was slow occasionally. Finally I
bought an external USB case for an NVME SSD and a fast NVME SSD.
I can only recommend that: It's *much* more fun using Qubes OS. VMs
start in maybe 2-3 seconds instead of 30-40 seconds...

Regards,
Ulrich
P.S.: I'm using an external drive for Qubes because I have filled my
four harddisks with other stuff already, and a fifth harddisk would
would have bee an organizational challenge with the desktop case I have.
