Hello everybody, Does anybody knows if is doable to run X in uml (not Xnest or similars) ? Rodrigo |

xterm and such are very easy to have with ssh and xforwarding, but I have never tried to have a complete desktop.

The problem with this idea is that a »real« X server expects to talk to graphics hardware of some description. VMware & co. solve this problem by actually emulating the registers etc. of a suitable graphics chip, but UML doesn't really deal in hardware; all it does is to present a Linux system call interface. I suspect the nearest thing to a »real« X server on UML would be something like Xvnc, which gives you a desktop-type X session that you can connect to using a VNC client. Anselm -- Anselm Lingnau ...

Adding framebuffer support to UML shouldn't be that hard. There was a patch which did that (never worked for me), you could then run X with the fbdev driver. |

I do not understand the need here, any application such as wireshark, firefox ... can be run graphically with ony a ssh and xforwarding, why exactly would we need a link to the real hardware?

Hi Vincent, clownix wrote: > I still don't get the reason behind the question, I am just curious, > you must have a good reason and the way I use uml, I never need more > than graphical applications. There could be lots of reasons, obviously I can only speak for myself (not sure what the original poster's intent was) and top of my list would be security: running UML in graphical framebuffer that only interacts with the local X server at the pixel level will be infinitely more secure. Another important one is that the X server would not be aware of the fact that it is running virtualized, whereas using ssh/Xvnc/etc does require explicit user setup, which is not ideal for testing unmodified generic setups. I really do think this would be a great feature to add to UML. I would have thought that adding a simple memory backed framebuffer should be easy enough.. (from memory, there was more to it than that though..) > nagafix is a place where there are uml linux and rootfs, I also make > machines, but I make my kvms with a boot sector and grub in it, how can > you mix your rootfs so that you can do both uml and kvm? KVM can handle raw disks just like UML. What is the difficulty you are encountering?
