I ran two plan9 guests for over two hours now on my laptop with no crash. They are both doing a ping every 10 ms and continuous floating pt additions. kqemu is enabled but not kernel-kqemu (as plan9performance under kernel-kqemu is abysmal). This is a Pentium M machine with 1GB of memory, running FreeBSD-current. plan9 is not very resource hungry (RSS is about 70MB) so if this is a resource related problem my test won't catch it. A quick reading of kqemu-freebsd.c does not reveal any problems for a uniprocessor machine (but I am not too sure of SMP). Can people who are seeing crashes or hangs provide some more information? - symptom: (host crashes, guest crashes, guest hangs, guest loses its mind) - freebsd version (also if UP or SMP version) - processor - command line used to invoke each qemu instance - what guest oses are run when this happens - if this is triggered more often by specific guest programs - what happens if you run the same guests with less memory. - output of sysctl kern.smp.cpus - VSZ and RSS of these images (from ps axlw). - whether -kernel-kqemu was used I am hoping a pattern will emerge that will help us debug this. _______________________________________________ Qemu-devel mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/qemu-devel
