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

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.
