Hello team, Good day. This is Pinion from EMT and I want to highlight the business impact of this bug (ACE EN-64350). There was an incident previously where the VM rebooted unexpectedly, later it was found as a bug in RHEL. Last Friday they went ahead and patched RHEL and rebooted and then hit this bug on RHEV. This is one of their Critical DBs and has a financial impact if it goes down. They need to patch the system asap to mitigate the RHEL bug, but they are looking for the RCA for last Friday's incident before that. Your early assistance on this would be highly appreciated. Thank you in advance. storaged is a dead component, please reassign to something sane in your product. Hi Qing, could you please try to reproduce this? It's 8.6 EUS. The same issue also exists on Red Hat Enterprise Linux release 8.9 Beta (Ootpa) 4.18.0-504.el8.x86_64 qemu-kvm-6.2.0-37.module+el8.9.0+19491+15e62c0a.x86_64 seabios-bin-1.16.0-3.module+el8.9.0+18724+20190c23.noarch edk2-ovmf-20220126gitbb1bba3d77-5.el8.noarch libvirt-8.0.0-21.module+el8.9.0+19166+e262ca96.x86_64 virtio-win-prewhql-0.1-240.iso This is fixed upstream.

The limit of disks accessible to SeaBIOS is src/config.h:#define BUILD_MAX_EXTDRIVE 16 in both RHEL8 and RHEL9. QE bot(pre verify): Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass. Reproduced it with seabios-bin-1.16.0-3.module+el8.9.0+18724+20190c23.noarch, boot a guest with 1 virio-scsi disk and 10 virio-blk disks, hitting "No bootable device". Tested with seabios-bin-1.16.0-4.module+el8.9.0+19570+14a90618.noarch, not hit this issue. 1. boot a guest with 1 virio-scsi disk and 10 virio-blk disks, the guest boot successfully. 2. boot a guest with 1 virio-scsi disk and 16 virio-blk disks, the guest boot successfully. And run seabios test loop, no new bug was found. So set status to VERIFIED. Versions: kernel-4.18.0-509.el8.x86_64 qemu-kvm-6.2.0-38.module+el8.9.0+19636+489b90af seabios-bin-1.16.0-4.module+el8.9.0+19570+14a90618.noarch Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
