Tuetenk0pp Posted August 29, 2023 Share Posted August 29, 2023 I have a problem with my VM setup. Every now and then, my previously working VM fails to start. When I try to solve the issue with a restart of libvirt via the VM Manager, libvirt fails to start. Once I fully reboot the server, everything works fine until a few days later, the problem reoccurs. How can I solve that issue? I attached two diagnostics: one before I tried to restart libvirt and the other one just after it in case some log gets overwritten. I noticed these issues in the libvirt log: virNetSocketReadWire:1791 : End of file while reading data: Input/output error this appears every 10 minutes qemuDomainGetBlockInfo:11099 : invalid argument: invalid path Endeavouros_Cassini_Nova-03-2023_R2.iso not assigned to domain this appears every now and then and is related to a VM that I never started. I will remove the VM and see if that changes anything warning : qemuDomainObjBeginJobInternal:858 : Cannot start job (query, none, none) in API remoteDispatchDomainGetBlockInfo for domain Windows 11; current job is (modify, none, none) owned by (15916 remoteDispatchDomainAttachDevice, 0 <null>, 0 <null> (flags=0x0)) for (1777s, 0s, 0s) error : qemuDomainObjBeginJobInternal:893 : Timed out during operation: cannot acquire state change lock (held by monitor=remoteDispatchDomainAttachDevice) this is probably the most relevant section because it is related to the VM I am trying to start. error : qemuMonitorIORead:423 : Unable to read from monitor: Connection reset by peer and this is the first line in the libvirt log after I tried to restart the libvirt service. The VMs Tab reads 'Libvirt Service failed to start.' I will now restart the server and hope for somebody to help me unraid-server-diagnostics-20230829-0859.zip unraid-server-diagnostics-20230829-0920.zip Quote Link to comment
gilladur Posted November 7, 2023 Share Posted November 7, 2023 Hi Tuetenk0pp, where you actually able to fix the issue. I'm running currently into the same issues with my Win 10 VM. My Home assistant VM is not affected. Quote Link to comment

I'm running currently into the same issues with my Win 10 VM. My Home assistant VM is not affected. Actually not, BUT: Since the measured Powerdraw from the wall was lower with the VM on than off, I leave it running all the time. And I never had the issue again. Obviously, this does not work if you use the same HW in different VMs and you need to switch them on and off. 1 Quote Link to comment
