Hi, sorry for bothering, but the last time i heard something about asyn IO was on Feb 2nd. Fabrice said:
[quote] I have at least 5 items on my TODO list : 1) New kqemu which virtualizes both user and kernel code (currently in alpha stage but not released yet). 2) DMA block I/O (merged) 3) async block I/O (not merged yet) 4) Network adapter using DMA (not merged yet) 5) VGA acceleration (either improve Cirrus VGA or switch back to Bochs VGA for Win 2000/XP or Linux) [/quote] so 1) and 2) are in HEAD. I saw something concerning 5) too, i think. I'm not sure about 4) - but - well, I'm very curious about 3) :-) It's not in HEAD yet, isn't it? Why i'm curious? Well, i'm curious about the improvement it causes. You people once told me, that the boost will not be that significant. On the other hand, i see my host CPU usage going towards 100% just because the guest is doing some IO or ... or is it because of somethine else perhaps? To be concrete: have you guys ever run windows-update inside qemu? Well, my win2k guest consumes all CPU on the host for some reason. What might be the reason? (qemu is started with -kernel-kqemu -m 256 -soundhw es1370) Also windows-update's green "progress bar" inside the guest is stopping for let's say 3 or 5 seconds and not moving continuous. Is anybody experiencing the same or knows the reason? Thanks, Sven
