Thanks,
I'll check this problem.
Vadim.

Vadim,

We tested the free build driver on 32-bit Windows 7 and the symptom was the same. In other words, the latest driver source from https://github.com/YanVugenfirer/ is buggy and it was not workable at all.

Vadim,

I downloaded the latest Windows guest driver code from (https://github.com/YanVugenfirer/) and built the test binary driver code.
When I tested the release build Vioserial driver on 64-bit Windows 7, the driver seemed to wait for something to happen and the update driver Windows dialog simply just stayed in busy state. Finally, the Windows system entered a busy loop. However, if I tested the debugging build driver, the driver could be installed. But it took for a long time to complete.

Our installed Qemu is 1.0. Is there Qemu build requirement so that we can verify the vioserial driver? From my test, the latest code from (https://github.com/YanVugenfirer/) seemed to be worst than the one we tested before. Let me know if we did anything wrong.

This code is slightly buggy.
Please try Yan's repository
at github (https://github.com/YanVugenfirer/).
I believe that the most critical changes have been merged already by Yan into this public repository.
I will ask to update binaries and sources at fedoraproject site as well.

Best regards,
Vadim.

Vadim,

We downloaded the driver source from the following website.

Just to be sure that we are on the same page:
could you tell me about the origin of the source?
Is it the latest from the Yan's repository at github.com?

Vadim,

We built it from the driver source. Up to this moment, we always use the same binary to test Qemu.

What about vioserial driver itself? 
did you build it from sources or is
it one, available through RHEL channels?
