This bug also exists in kvm-83-140.el5.
Both 64bitwin2008 and 32bitwin2008 got BSOD during resuming after hibernation with 4cpu and 4G mem in the following env: host kernel: #uname -r 2.6.18-183.el5 kvm version: # rpm -q kvm kvm-83-147.el5 host cpu: processor : 3 vendor_id : AuthenticAMD cpu family : 16 model : 2 model name : AMD Phenom(tm) 9600B Quad-Core Processor host mem: 8G core dump analyse file will be attached.

Unrelated, please note you are using Vista SP1 / 2008 - which is the release versions. I think it's worth updating to SP2 as well (not that I think the bug is in the OS, but who knows).
Please repeat with Yaniv's request
(In reply to comment #9) > Please repeat with Yaniv's request Install 64bit win2008 sp2 and install all updates, still got the same bsod during resuming, and dump analyse file is same with the last.
Bugzilla changed the component of the bug. Moving back to 'kvm'.
Re-test with the same steps and host using the following packages: kernel-2.6.18-237.el5 kvm-83-224.el5 virtio-win-1.0.0-13.45801.el5 This issue does not exist. Guest can hibernate and resume successfully. So I will close this issue. Please re-open if I am wrong. Thanks qzhang
