It's hard to check, as without at least one of them the box does not boot, but I don't think the things (e.g., Firefox freezing or not starting) are necessarily related. In particular, you have in your Xen boot parameters list, this item: =C2=A0"dom0_mem=3D1024M,max:1024M" This means that, in dom0, you will "only" have 1GB of RAM available. And if you just login after boot and start Firefox, dom0 is where Firefox is going to be running... and 1G, that Firefox will have to share with the rest of Linux running as dom0, may be too few RAM for it. And in fact, in your last log, we see this (from dom0, not from Xen!): [=C2=A0=C2=A0851.644443] Out of memory: Kill process 1945 (firefox) score 3= 25 or sacrifice child [=C2=A0=C2=A0851.644461] Killed process 1945 (firefox) total-vm:1228008kB, = anon-rss:305536kB, file-rss:0kB If you want to run a graphical environment on that test box, and browse with Firefox, then you should increase the amount of RAM you allow dom0 to use. When I suggested you to use 1024, I was assuming (given how your work environment is setup) you were not going to do any such thing. > And the following > is still present in the log. >=20 > (XEN) traps.c:3290: GPF (0000): ffff82d0801c1cea -> ffff82d080252e5c > (XEN) d1v1 fault#1: mxcsr=3D00001f80 > (XEN) d1v1 xs=3D0000000000000003 xc=3D8000000000000000 > (XEN) d1v1 r0=3D0000000000000000 r1=3D0000000000000000 > (XEN) d1v1 r2=3D0000000000000000 r3=3D0000000000000000 > (XEN) d1v1 r4=3D0000000000000000 r5=3D0000000000000000 > (XEN) traps.c:3290: GPF (0000): ffff82d0801c1cea -> ffff82d080252e5c > (XEN) d1v1 fault#2: mxcsr=3D00001f80 > (XEN) d1v1 xs=3D0000000000000000 xc=3D0000000000000000 > (XEN) d1v1 r0=3D0000000000000000 r1=3D0000000000000000 > (XEN) d1v1 r2=3D0000000000000000 r3=3D0000000000000000 > (XEN) d1v1 r4=3D0000000000000000 r5=3D0000000000000000 >=20 Mmm... and this is with all Jan's patches applied? So, just to make sure we understand each others, you're saying that, again with all patches applied, and with you not doing anything significantly different between a) and b) below, the system either: =C2=A0a) crashes right after login, like this:=C2=A0http://paste2.org/KEAet= MHb =C2=A0b) does not crash (you're even able to try starting Firefox), but Xen =C2=A0 =C2=A0 produces the following output: http://paste2.org/C8WpyKOg Is this correct?
