[Qemu-devel] Help:System crash when a large file is copied.

[韦理]

Hi everyone


I am trying to run qemu(v0.8.2) on a diskless linux system whose root file 
system is NFS. The disk image of Qemu is located on the NFS server. But we 
found the guest os  would crash down if a large file (e.g. 200M) is replicated 
to emulate hard disk. I have tested serveral guest os such as WinXp SP2, 
linux(kernel 2.6) and this problem always happens. And I also copy lager files 
on guest os which runs on normal linux (Disk image is located on local disk) 
and it's alright. I guess maybe it is caused by IO rate of NFS is not match the 
hard disk emulated by qemu? I don't kow whether it's reasonable, since there is 
nothing on the log about this problem.Please give me some advices to find the 
reason and fix this problem. Thanks a lot.
