Actual results: The guest got an bsod issue Expected results: The guest works well Additional info:
QE can reproduce the bz on rhel6.4 host too.thanks.
(In reply to comment #3) > QE can reproduce the bz on rhel6.4 host too.thanks. The issue cannot be reproduced while upgrading driver from 1.4.0 to 1.5.4.So please double check it,thanks.
Hi Min, Could you please reproduce the problem with kernel memory dump instead of small? Thank you, Vadim.
