-qemu-system-i386: void msix_vector_use(PCIDevice *, unsigned int): Assertion `vector < dev->msix_entries_nr' failed.
-Description of problem:
-While fuzzing, we observed a assertion failures in several virtio devices supporting msi-x functionality.
-Steps to reproduce:
-Here is qtest reproducer:
-```bash
-cat << EOF | qemu-system-i386 -display none -machine accel=qtest, -m 512M -machine pc -nodefaults \
--device virtio-mouse-pci,vectors=19923041 -qtest stdio
-outl 0xcf8 0x80001020
-outl 0xcfc 0xe0800000
-outl 0xcf8 0x80001004
-outw 0xcfc 0x02
-write 0xe0800010 0x4 0x6100
-EOF
-```
-
-and execution log:
-```
-cat << EOF | qemu-system-i386 -display none -machine accel=qtest, -m 512M -machine pc -nodefaults \

-If you need more information, let me know so I can discuss more about this issue.
-Additional information:
-```c
-int msix_init(PCIDevice *dev, unsigned short nentries,
-              MemoryRegion *table_bar, uint8_t table_bar_nr,
-              unsigned table_offset, MemoryRegion *pba_bar,
-              uint8_t pba_bar_nr, unsigned pba_offset, uint8_t cap_pos,
-              Error **errp);
-int msix_init_exclusive_bar(PCIDevice *dev, unsigned short nentries,
-                            uint8_t bar_nr, Error **errp);
-```
-
-`msix_init` accepts `nentries` as `unsigned short` type. 
-
-```c
-static void virtio_pci_device_plugged(DeviceState *d, Error **errp):
-
-    ...
-
-    if (proxy->nvectors) {
-        int err = msix_init_exclusive_bar(&proxy->pci_dev, proxy->nvectors,
-                                          proxy->msix_bar_idx, NULL);
-        if (err) {
-            /* Notice when a system that supports MSIx can't initialize it */
-            if (err != -ENOTSUP) {
-                warn_report("unable to init msix vectors to %" PRIu32,
-                            proxy->nvectors);
-            }
-            proxy->nvectors = 0;
-        }
-    }
-```
-
-When virtio-pci device is initialized, `proxy->nvectors` (`uint32_t` here) is casted into `unsigned short`.
-This causes inconsistency between `msix_entries_nr` and `nvectors` and triggers the above crash.
-
-While this is due to setting invalid value to `nvectors`, we need proper handling of the wrong value in the configuration.
