[Qemu-devel] Assertion failed when I reduced HW support

2015-05-30 Thread Марк Коренберг
I'm trying to reduce qemu as much as possible, so I decide to cut off some hardware support, i.e. bluetooth, audio, USB and so on. After some time, compilation succeeded, but when I run qemu --help, assertion failed. $ i386-softmmu/qemu-system-i386 --help ** ERROR:qom/object.c:165:type_get_paren

[Qemu-devel] How to overclock guest timers?

2014-05-05 Thread Марк Коренберг
What I want - is to make all virtual clocks run faster. This means, for example, if I run command 'sleep 10' on the guest, and virtual clocks are 10 times overclocked, this command should take 1 real second. In other words, all timers should be 10 times faster, even timers that wait for IO in the g

[Qemu-devel] What is the cause of -net socket, mcast bad performance?

2012-08-16 Thread Марк Коренберг
Hello. On my PC, tap <--> bridge <--> tap networking gives 600 megbit. Exactly the same, but -net socket,mcast gives about 1 megbit (!) I do not understand why. In my mind, -net socket,mcast is the same as tap, but ethernet frames are going in much simplier way: instead of qemu1 -> /dev/tun ->

[Qemu-devel] Timers speedup

2012-08-16 Thread Марк Коренберг
Hello. Please advice me how I can speed up all timers inside VM. I mean patch for qemu that will tick all timers, say, twice as faster. So I expect, that time in VM will go twice as fast, "sleep 1" command will last 0.5 real seconds, real time clocks will be twice as faster, TCP timeouts will be p

[Qemu-devel] Proper usage of qemu_get_clock_*

2012-08-16 Thread Марк Коренберг
Hello! I'm looking at some places in qemu and saw that some code calculate next timer alarm (for qemu_mod_timer) use qemu_get_clock_* and specify specific timer, like vm_timer. I think, that it's more clean is to use timer's clock instead of hardcoded clock. For example, instead of qemu_mod_time

[Qemu-devel] Will qemu emulate m68k macintoshes ?

2008-01-18 Thread Марк Коренберг
I saw, that qemu fully support m68k processor. but what about other macintosh hardware? i want to run classic macos inside qemu. it is possible? which is the status? (if any work going) The my real task is to install debian linux for m68k on hard drive using qemu and then place this hard disk int
