I have the following problem reproduced on  centos6 and RH6. 

When I am doing a recursive grep on my Clearcase view using a 3rd party program
called Windows Grep. On every run, the VM would crash (windows kernel crash
where the cause is reported as unknown by Microsoft) up after the program ran
about an hour or so.

The qemu-kvm version is:
