jude Posted December 21, 2014 Share Posted December 21, 2014 Finally have a stable working Win8.1 VM! Very happy to have achieved this milestone. It didn't seem quite as easy to achieve with an AMD motherboard, but it does work amazingly well once its up and running. I have to admit for a while I was considering changing to an Intel board. Motherboard GA-990FXA-UD5 Rev 3.0 Beta Bios GPU HIS 1GB Radeon 6450 Lots of thanks to all of the KVM gurus. Special mention Dmacias, JonP, Peter_SM, Archedraft, JustinChase and lots of others who have been documenting there Plugins, systems, issues and successes. I am sure that there is lots to tweak in my system and I still have one major issue with my microsoft wireless keyboard crashing but I am sure this can be fixed. I thought I would post what I have working just in case it helps anyone else.

I added the following code to syslinux.cfg "iommu=pt iommu=1" prior to adding the above code when I did a dmesg | grep AMD-Vi I would get: AMD-Vi: Enabling IOMMU at 0000:00:00.2 cap 0x40 AMD-Vi: Lazy IO/TLB flushing enabled but nothing about passthrough. With the updated syslinux.cfg dmesg | grep AMD-VI gets: root@Tower:~# dmesg | grep AMD-Vi AMD-Vi: Found IOMMU at 0000:00:00.2 cap 0x40 AMD-Vi: Interrupt remapping enabled AMD-Vi: Initialized for Passthrough Mode I made this change based on the October 17th,2012 post on this forum http://ubuntuforums.org/archive/index.php/t-1818433.html (not sure if its ok to include this link) Seemed to make a difference. With a corded USB keyboard and mouse attached and passed through everything works great. High bitrate movies in Plex play perfectly. Have not tried games yet. Passing through my Microsoft wireless keyboard and trackpad is not so great. The VM starts and GPU passthrough works as expected. The keyboard trackpad works for a short time (30 seconds to a minute or two and then the keyboard and trackpad stop functioning all together. I am forced to shutdown the VM from VM Manager.

reluctantflux Posted December 22, 2014 Share Posted December 22, 2014 I had the same problem the Microsoft All-in-One keyboard. I ended up returning it for a Logitech and haven't had any issues since. I believe the issue stems from the device going into sleep mode after a short period (10 seconds?) of inactivity to save power. I got frustrated and just returned the unit since it was a new purchase. Perhaps you could look into some of the nitty gritty driver details on the device going to sleep or passing through the USB controller, instead of individual USB devices. Quote Link to comment
jude Posted December 22, 2014 Author Share Posted December 22, 2014 Thanks for the feedback. I had a feeling it would be something like that. Unfortunately I am beyond my return window, so I have just started trying to pass through a USB controller but I am having some issues with that too.
