reluctantflux Posted November 20, 2014 Share Posted November 20, 2014 Sooooo, I added a new video card, and bound it to my HTPC, and now my Disk Activity active time is 100%. Also, the average response time is crazy high, like 2000-30000ms. Has anyone seen anything crazy like this before? It's a qcow2 on my SSD cache drive. Quote Link to comment
reluctantflux Posted November 20, 2014 Author Share Posted November 20, 2014 This vm was working fine with a different card (ATI). New card is Nvidia. No docker containers are running that share the cache drive. I did take a snapshot of the machine yesterday, but it was working fine earlier today after the snapshot but before the new vid card.

reluctantflux Posted November 20, 2014 Author Share Posted November 20, 2014 Switched back to ATI. Definitely something going on with the Nvidia. Maybe it'll calm down if I can get the driver installed. I guess I should mention, the ATI card is a Radeon HD 7770, and the Nvidia is a 8400 GS. Quote Link to comment
reluctantflux Posted November 20, 2014 Author Share Posted November 20, 2014 Was simply the drivers. Wow that was brutal. Quote Link to comment
bungee91 Posted November 20, 2014 Share Posted November 20, 2014 What drivers did you switch from/to? I've noticed this sporadically in both an Nvidia & AMD pass through configuration. Quote Link to comment

reluctantflux Posted November 20, 2014 Author Share Posted November 20, 2014 I had ATI drivers installed, and then switched which card was being passed through and that's when the disk activity went crazy. Once I got the Nvidia drivers installed (which was painfully slow), it resumed to regular speed. There were some issues with the Nvidia card, and I reverted back to the ATI, and it worked fine until a reboot, and now my whole VM is hosed. Trying a system restore. I had taken a snapshot, but for some reason, he decided to delete himself.... *sad trombone noise* Might have to just rebuild this guy from scratch. He was from a Virtualbox build anyways. Might be good to do fresh all through KVM. Quote Link to comment
jonp Posted December 3, 2014 Share Posted December 3, 2014 I've had the issue with disk activity and latency like that happen to me once or twice and was wondering the issue. I don't think its driver related in the way you think. Is your ssd formatted with btrfs that the qcow disk is on? Quote Link to comment

I will say I've never noticed this on my VM (that is up 24/7) that has no pass through being used. Only on the one with, and it was as expected somewhat sporadic of an occurrence.

I was able to restore from my original VDI file that I converted to qcow2, so it wasn't a huge headache to get back to regular. I love VM's. So easy to backup the hard drive file and revert back if necessary. Quote Link to comment
