Hi, acrow 

virtio-win-0.1-15.iso is not RHEL6.x officially supported build .
Could you try with our offically virtio-win package (virtio-win-1.4.0-1.el6.norach)?

Best Regards,
Mike

Hi mike,

I am not using RHEL6 as my host, so this is not an officially supported release, and I am unable to obtain such a release without an RHEL6 license.

I am running on ubuntu 10.04 LTS, but I believe this is the correct place to report virtio-win bugs as I think you are now the developers since acquiring Qumranet.

I have reported a similar bug against 710040 for the network drivers and it was accepted. I hope it is still possible to help with this issue.

Can we see the entire crash dump file?

Thanks,
Vadim.

The virtio-win bugs from Fedora should be reported on the fedora-virt mailing list. In theory it can also be a host issue. I'll keep the bug in closed state but you can continue to post comments here.

Re: comment 4: The dump may contain private data - is it possible to obtain some kind of NDA?

Re: comment 5: So does that mean if Fedora is not my host (Ubuntu is) it's going to be next-to-impossible to fix this?

Thanks,

Alex
