Green Dragon Posted November 21, 2022 Share Posted November 21, 2022 Hiya! After upgrading to 6.11.5 I am seeing the following errors in the libvirt log, about every 10 minutes: 2022-11-21 02:38:20.190+0000: 13082: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2022-11-21 02:48:23.307+0000: 13082: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2022-11-21 02:58:26.536+0000: 13082: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2022-11-21 03:08:29.686+0000: 13082: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2022-11-21 03:18:32.955+0000: 13082: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error Thoughts?

baboolian Posted November 21, 2022 Share Posted November 21, 2022 Same here (although it started in 6.11.4), and when I launch my previously working windows VM with gfx card passed through it locks up Unraid and I have to do a force reboot Quote Link to comment
Green Dragon Posted November 21, 2022 Author Share Posted November 21, 2022 Also found that If I stop all VMs, disable VMs, then enable VMs the libvirt service fails to start. A complete reboot of UnRaid is required to get VMs working again. Quote Link to comment
exus Posted November 22, 2022 Share Posted November 22, 2022 I installed unraid on my new server for the first time two days ago and I've the same error every 10 minutes Quote Link to comment
Gonzo-the-great Posted November 23, 2022 Share Posted November 23, 2022 Will jump in here and say "Me too". From my research, it's possible that this is a known issue with libvirt library, but nothing definitive to support that. 1 Quote Link to comment
bosswaz Posted November 27, 2022 Share Posted November 27, 2022 Im living the same issues you are describing...however my VM will not shutdown clean...runs fine during the day. If I try a grace full shutdown the system locks up and I need to power down to restart. Also something occurs overnight as in the morning I find its locked up...again I need to power down to restart as a Grace full shutdown locks up unraid. Quote Link to comment
SimonF Posted November 27, 2022 Share Posted November 27, 2022 There messages are likely due to the virsh client disconnecting from libvirtd are you running VMBackup or similar plugins? Quote Link to comment

I am running VMBackup. No other VM related plugins though. Is this typical behavior for a plugin such as VMBackup to cause a connect/disconnect which generates a libvert I/O error every ten minutes? Is this a reportable bug? VMBackup? Libvert? UnRaid? Quote Link to comment

Not sure dont use VMBackup. Do you want to post diagnostics for review to see if I can see anything. Libvirt has been the same since 6.11.1 did you have the issue pre 6.11.5? Maybe related to something else. Quote Link to comment

bosswaz Posted November 28, 2022 Share Posted November 28, 2022 Solved my problem by isolating iommu for my radeon video card and then binding to vfio...in the tools system devices tab...took a long while to find the solution but im happier now... Quote Link to comment

Awesome! Could it be as simple as me needing to bind the 'Serial bus controller: Intel Corporation Comet Lake' to iommu for my 2003 server qemu issue referenced above? Quote Link to comment

I have the exact same issue, I am running portainer (docker images) inside a VM, wondering if some weird VTx issue, I only started noticing on the last 2/3 versions of unraid. Quote Link to comment

After a reboot, the VM run again, the log entries come back. My behavior is in this thread Quote Link to comment
bobobeastie Posted January 19, 2023 Share Posted January 19, 2023 I just started having this same issue after changing all of my cache mounts from referencing user to the cache drives name because I saw a youtube video about IO Wait. Changed the 2 path settings in the VM config back and still have the issue. it's a home assistant VM if anyone cares. I was having rebooting issues before today, but I found a message regarding insufficient memory, which I think I solved by changing the memory settings for the VM, so probably unrelated. Reboot didn't do anything. Tried creating a new debian VM and that wont start either. Diagnostics attached are from after reboot and Debian attempt/test. nastheripper-diagnostics-20230119-1642.zip Quote Link to comment
nongfeng Posted March 1, 2023 Share Posted March 1, 2023 这个问题有什么进展吗?我也遇到了同样的问题,暂时不清楚会有什么影响 下面是我的诊断报告 nongfeng-diagnostics-20230301-1046.zip Quote Link to comment
JimmyGerms Posted March 1, 2023 Share Posted March 1, 2023 I'm getting these errors too every 10 min. I rebuilt my unRAID flash from scratch and setup everything manually again one by one to track down another issue and noticed it happening. Not sure where to look for a further trace stack on the error. I suspect this is happening to quite a few people? Quote Link to comment

SimonF Posted March 7, 2023 Share Posted March 7, 2023 This is the feedback from Libvirt developers. The socket connection to libvirtd / other daemons was abruptly closed. Essentially you can almost always ignore this error message as being mostly harmless. With regards, Daniel Quote Link to comment
reboot81 Posted March 20, 2023 Share Posted March 20, 2023 Same issue here. virNetSocketReadWire:1791 : End of file while reading data: Input/output error VM (WS2019) no longer booting. The vdisk contains "C:" (verified by mounting it) but the VM doesn't see the drive at boot and fails. 6.11.5 Quote Link to comment
