November 21, 20223 yr 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?
November 21, 20223 yr 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
November 21, 20223 yr Author 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.
November 22, 20223 yr I installed unraid on my new server for the first time two days ago and I've the same error every 10 minutes
November 23, 20223 yr 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.
November 27, 20223 yr 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.
November 27, 20223 yr Community Expert There messages are likely due to the virsh client disconnecting from libvirtd are you running VMBackup or similar plugins?

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?

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.

November 28, 20223 yr 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...

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?

A complete reboot of UnRaid is required to get VMs working again. 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.

After a reboot, the VM run again, the log entries come back. My behavior is in this thread
January 19, 20233 yr 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
March 1, 20233 yr 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?
March 7, 20233 yr +1 seeing the same issue, 10min like clockwork 2023-03-01 13:47:51.553+0000: 11837: info : libvirt version: 8.7.0 2023-03-01 13:47:51.553+0000: 11837: info : hostname: jdstorage5 2023-03-01 13:47:51.553+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 13:57:52.293+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 14:07:53.041+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 14:17:53.774+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 14:27:54.536+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 14:37:55.269+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 14:47:56.013+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 14:57:56.750+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 15:07:57.579+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 15:17:58.364+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 15:27:59.206+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 15:38:00.373+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 15:48:01.279+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 15:58:02.275+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 16:08:03.318+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 16:18:04.442+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error 2023-03-01 16:28:05.263+0000: 11837: error : virNetSocketReadWire:1791 : End of file while reading data: Input/output error Edited March 7, 20233 yr by darxtorm
March 7, 20233 yr Community Expert 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
March 20, 20233 yr 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
