Description of problem: This is a bug report highlighting RHEL bug report of the same name found at: https://bugzilla.redhat.com/show_bug.cgi?id=2079938 This bug prevents booting a guest OS with multiple disks. For me it shows up when I try to boot a Windows Server 2016 VM with 3 attached disks (1 SATA, and 2 VirtIO). This worked fine in Fedora 36. It seems the patch has been applied to qemu 7.1.0. Version-Release number of selected component (if applicable): qemu 7.0.0-9 How reproducible: Every time. Steps to Reproduce: 1. Take a VM with multiple disks (of VirtIO) and try to boot it in Fedora 37. 2. Watch it segfault. Actual results: qemu segfaults. journalctl: Nov 15 12:19:48 cloud-dev01 systemd-coredump[4688]: [🡕] Process 4488 (qemu-system-x86) of user 107 dumped core. libvirtd qemu log: runner-1284-project-2316-concurrent-0-job-1000464.log:failed to set up stack guard page: Cannot allocate memory Expected results: System should boot as expected. Additional info: I believe this has been fixed upstream, and in the errata put out by RHEL today for 9.1. https://access.redhat.com/errata/RHSA-2022:7967 Would it be possible to backport?
