So 4 GB is fine to run 2/3 light VM ? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] RAM for Qubes OS
Hi there, I have a Xiaomi Air Notebook 12.5": - Intel Core m3-6Y30 Dual Core 0.9GHz, Up to 2.2GHz - 12.5 inch IPS Screen with 1920 x 1080 Resolution - 4GB DDR3 RAM for Advanced Multitasking - 128GB SSD Storage Capacity (http://www.gearbest.com/laptops/pp_416105.html) I wonder if 4GB of RAM is enough to run Qubes OS. I know that 4GB is the minimum required nevertheless I won't install Qubes on it if I can't open 2 AppVM at the same time or if the laptop is very slow. Thank you, Feedbacks appreciated if someone alreday installed Qubes on the Xiaomi :) -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
