[pve-devel] New virtio-win driver 0.1-94.iso version in fedora proyect

[Alexandre DERUMIER]

Hi again,

It seem that it was a bug with qemu 2.2rc2, maybe related to this bug
http://git.qemu.org/?p=qemu.git;a=commit;h=771b6ed37e3aa188a7485560b949a41c6cf174dc

I have rollback to qemu 2.1, and now it's works fine.

I'm going to do some benchmark to see if we have improvement

I have tested with win2012R2, 

I don't have BSOD, but network don't work when multiqueue is enabled. 

I'll try to dig a little more.

Thanks for the report, I'll try today with win2008R2 and win2012r2

Hi 

I have tested this: 

Win2008R2 SP1 VM + 
net0: ......,queues=<numberofqueue> 
----------------------------------------- 
= bsod 

With 8 and 4 numbers of queues, it isn't stable.
