Public bug reported: == Comment: #0 - Fabian Zu?iga Barajas <[email protected]> - 2025-04-16 18:16:18 == ---Problem Description--- I am currently using KVM to virtualize under ubuntu 24.04, it seems like everything works fine, virtual machine is working properly, I have tested IO execution on baremetal ubuntu physical machine and also under virtual machine, however it seems like VM looses reference to volumes attached after some relative time, sometimes it takes an hour sometimes it takes 20, Important to mention this scenario only ocurres in virtualized SCSI disks but not on volumes attached to baremetal, i have tried changing resources assigned to VM and assign less volumes to pool on VM but error is still presented. ---Steps to Reproduce--- 1. Go to edit -> Connections Details -> Storage 2. Add pool -> Multipath Device Enumerator 3. Go to virtual hardware details 4. Add hardware -> passthrough (SCSI) 5. Execute I/O to devices registered under lsblk
Failure occurs after some hours (relative) on step 5 ---uname output--- Linux ARCSR630516P1 6.11.0-21-generic #21~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Mon Feb 24 16:52:15 UTC 2 x86_64 x86_64 x86_64 GNU/Linux ---Debugger--- A debugger is not configured Machine Type = ThinkSystem SR630 V2 Contact Information = [email protected] Userspace tool obtained from project website: na The userspace tool has the following bit modes: 64 Userspace tool common name: na Userspace rpm: na *Additional Instructions for [email protected]: -Attach ltrace and strace of userspace application. ** Affects: qemu (Ubuntu) Importance: Undecided Assignee: Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) Status: New ** Tags: architecture-x8664 bugnameltc-212432 severity-medium targetmilestone-inin2510 ** Tags added: architecture-x8664 bugnameltc-212432 severity-medium targetmilestone-inin2510 ** Changed in: ubuntu Assignee: (unassigned) => Ubuntu on IBM Power Systems Bug Triage (ubuntu-power-triage) ** Package changed: ubuntu => qemu (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2107529 Title: Ubuntu24.04: KVM passthrough SCSI_disks IO fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/2107529/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
