It's exhausting the limit on the MemoryRegionSections. We probably should document the limit and replace the crash with a less dramatic failure mode.
(In reply to Paolo Bonzini from comment #2) > It's exhausting the limit on the MemoryRegionSections. We probably should > document the limit and replace the crash with a less dramatic failure mode. Hi Paolo, I am not sure how could we limit the max PCI devices based on maximum MemoryRegionSections. Replacing the crash with an error message is a start. Thanks, Marcel

Sorry,Please ignore the test results of comment #20. Corrected test results are as follows： qemu core dump when boot up 553 disks
No fix upstream yet. This would need some kind of extension to the memory API of qemu. Yes it's a crash but not one guests can trigger. So not high priority imho. Will start a discussion upstream.
only update test result: for rhel6.10 guest,can boot up 112 disk with "virtio-blk-pci-transitional" device for rhel7.7 guest, can boot up 552 disk for rhel8.1.0 guest, can boot up 156 disk host version: qemu-kvm-4.0.0-6.module+el8.1.0+3736+a2aefea3.x86_64 kernel-4.18.0-119.el8.x86_64 seabios-1.12.0-3.module+el8.1.0+3627+66216cf4.x86_64 Guest: rhel6.10 (kernel-2.6.32-754.18.1.el6.x86_64) rhel7.7 (kernel-3.10.0-1061.el7.x86_64) rhel8.1.0 (kernel-4.18.0-119.el8.x86_64)
QEMU has been recently split into sub-components and as a one-time operation to avoid breakage of tools, we are setting the QEMU sub-component of this BZ to "General". Please review and change the sub-component if necessary the next time you review this BZ. Thanks
