I had the same issue. Renaming the /boot/config/network.cfg file and rebooting resolved it for me. Many thanks.

I had this exact issue and changing to q35-2.10 (machine type) potentially resolved it for me. I say potentially because I did install a completely new VM instead of modifying the existing one.

How do I run a scrub from the GUI? The NVMe drive is unassigned and not in the cache array. I can see how to scrub cache drives but not unassigned ones. Thanks!

I haven't rebooted yet, the diagnostics zip is attached. tower-diagnostics-20180206-2335.zip

Many thanks @johnnie.black , that has resolved the disabled disk issue. Regarding the corruption warnings, I've tried scrubbing and it results in the following: dmesg shows the following: There is only 1 file on this NVMe drive and that is my Windows VM img. Does this mean it is corrupted, and if so is there a way I can repair it? Note that I'm currently using this Windows VM with no issues.

My bad, thought that was what I'd attached. Have attached it now. tower-diagnostics-20180205-1309.zip

Having an issue with a 4TB drive (part of the array) which is now showing as disabled in Unraid. Apparently the contents of this drive are being emulated but the only other disk in the array (besides the parity) is 500GB and my used data is roughly 1TB. I'm confused, is it emulating it using only the parity? I've attached my diagnostics file if anyone would be kind enough to advise what I should do. Has the drive failed? I'm worried removing the disk and installing it on the array again will delete my data. Thanks! tower-smart-20180205-1021.zip

I did isolate the CPUs and pinned them to the VM (and used emulatorpin) but it didn't resolve the issue I was experiencing with file transfers unfortunately. The VM still lagged whenever transferring a file from the array to the VM. I suspect the actual VM is misconfigured in some way.

OK, I've installed another fresh Windows 10 VM using Q35-2.10 (instead of i440fx-2.10) and this is working fine. Unless the different machine type solved it, something is obviously incorrectly configured/broken on the other VM. File transfers from the array on the new VM are fast (100MB/s+) and most importantly it doesn't cause any hangs/stutters. Also audio has improved as I get no crackling now at all - at the moment everything is working perfectly. I'm not sure what's wrong with the other VM and I doubt I'll try to fix it now. If anyone has any ideas I would be very interested!

The cause of the stutter/hang does appear to be due to file transfers causing 100% load on the VM CPU 1, please see the attached screenshot which shows this. File transfers are around 18-20MB/s. If I copy files via SSH directly on the Unraid server from one HDD to another HDD on the array, this works fine. There's no lag within the VM and the transfer speeds are mostly 100MB/s or above. Obviously because I'm using a vdisk file for the VM I can't just use SSH as a workaround and transferring files to/from the VM within Windows is painful. I can't figure out what's causing this. Any ideas? EDIT: Transferring files on a CentOS VM works fine. I'll try installing another Windows 10 VM now to rule that out.

I'm experiencing a strange issue where transferring files within my Windows 10 VM from a Share causes the VM to stutter, meaning the cursor no longer moves smoothly and the entire OS is prone to freezing momentarily. When the file transfer finishes everything goes back to normal (working perfectly). My issue is related to this: but the whole system doesn't lock up, only the VM freezes/hangs. I've tried increasing "md_num_stripes" to 8192 (mentioned in the Tips and Tweaks Wiki - https://wiki.lime-technology.com/Tips_and_Tweaks) as this seemed to be the same issue I'm experiencing, but it hasn't helped unfortunately. I'm running unRAID version 6.4.0-rc10b. I've attached my diagnostics file, let me know if you need anything else (ie, the VM XML?). Many thanks. tower-diagnostics-20171110-1217.zip

Testing again with AMD drivers uninstalled and I'm not getting any FPS issues, YouTube videos load fine without any stuttering. Looks like it's a driver issue. I'm using a Sapphire R9 290 TRI-X. Obviously I can't continue using the VM without the video drivers installed, anyone else experienced this?

Thanks coppit. I've made these changes to my XML (have updated the first post with the new XML now) but unfortunately I'm still experiencing the same FPS issues. It's worth mentioning that Chrome in general is laggy, loading pages which contain images makes Chrome stutter to the point where it stops responding. Likewise, games drop frames when loading new areas. Had some problems with audio initially but that's resolved now (driver issue).

I'm experiencing some FPS issues with a Windows 10 VM and Ryzen 7 1700. Just playing a YouTube video isn't possible at the moment, it drops frames constantly (especially when I move the mouse over the video or scroll, for some reason) but playing a video via VLC is fine. Audio is also fine, no crackling, etc. It seems like I've tried everything from pinning CPUs (and using isolcpus) to enabling/disabling Nested Page Tables. I've also reinstalled Windows multiple times with different CPU/RAM configurations with/without AMD video drivers installed. None of these changes make any difference. If anything it appears to be network/drive related, for example moving a file from one drive to another will cause considerable lag (ie. moving windows around has a noticeable stutter). I guess that also explains why YouTube/Browsers lag and VLC doesn't. Could it be an issue with a drive?
