 ### Does Qubes run every app in a separate VM?
 
-No! This would not make much sense. Qubes uses lightweight VMs to create security domains (e.g., "work," "personal," and "banking,"). A typical user would likely need around five domains. Very paranoid users, or those who are high-profile targets, might use a dozen or more domains.

 ### What's so special about Qubes' GUI virtualization?
 
 We have designed the GUI virtualization subsystem with two primary goals: security and performance. Our GUI infrastructure introduces only about 2,500 lines of C code (LOC) into the privileged domain (Dom0), which is very little, and thus leaves little space for bugs and potential attacks. At the same time, due to the smart use of Xen shared memory, our GUI implementation is very efficient, so most virtualized applications really feel as if they were executed natively.

 Absolutely.
 
 ### Can I run applications, like games, which require 3D support?
 
-Those won’t fly. We do not provide OpenGL virtualization for AppVMs. This is mostly a security decision, as implementing such a feature would most likely introduce a great deal of complexity into the GUI virtualization infrastructure. However, Qubes does allow for the use of accelerated graphics (OpenGL) in Dom0’s Window Manager, so all the fancy desktop effects should still work.

+### How much disk space does each qube require?
 
-Each AppVM is created from a TemplateVM and shares the root filesystem with this TemplateVM (in a read-only manner). This means that each AppVM needs only as much disk space as is necessary to store its own private data. This also means that it is possible to update the software for several AppVMs simultaneously by running a single update process in the TemplateVM upon which those AppVMs are based. (These AppVMs will then have to be restarted in order for the update to take effect in them.)

 ### How much memory is recommended for Qubes?
 
-At least 4 GB. It is possible to install Qubes on a system with 2 GB of RAM, but the system would probably not be able to run more than three AppVMs at a time.

 ### Can I install Qubes on a system without VT-x?
 
-Yes. Xen doesn't use VT-x (or AMD-v) for PV guest virtualization. (It uses ring0/3 separation instead.) However, without VT-x, you won't be able to use fully virtualized VMs (e.g., Windows-based AppVMs), which were introduced in Qubes 2. In addition, if your system lacks VT-x, then it also lacks VT-d. (See next question.)

 ### Can I install Qubes on a system without VT-d?
 
-Yes. You can even run a NetVM, but you will not benefit from DMA protection for driver domains. On a system without VT-d, everything should work in the same way, except there will be no real security benefit to having a separate NetVM, as an attacker could always use a simple DMA attack to go from the NetVM to Dom0. **Nonetheless, all of Qubes' other security mechanisms, such as AppVM separation, work without VT-d. Therefore, a system running Qubes will still be significantly more secure than one running Windows, Mac, or Linux, even if it lacks VT-d.**
