- Urgent
When attempting to pass through the 8111 network interface (Realtek RTL8111) to a virtual machine running on Unraid, the VM fails to start and QEMU throws an assertion failure related to PCI IRQ handling:
internal error: QEMU unexpectedly closed the monitor (vm='openwrt'): qxl_send_events: spice-server bug: guest stopped, ignoring qemu-system-x86_64: ../hw/pci/pci.c:1633: pci_irq_handler: Assertion 0 <= irq_num && irq_num < PCI_NUM_PINS' failed.
Steps to Reproduce:
Configure a virtual machine in Unraid.
Pass through the 8111 network interface (Realtek RTL8111) to the VM.
Start the virtual machine.
The VM fails to launch, and the error message appears in the log.
Expected Behavior:
The virtual machine should start successfully with the 8111 network interface passed through, without any errors related to PCI IRQ handling.
Actual Behavior:
The virtual machine fails to launch, and QEMU throws an assertion failure related to pci_irq_handler in pci.c.
Environment:
Host OS: Unraid
Guest OS: OpenWrt
Network Interface:
8125 (used for host connectivity)
8111 (passed through to VM, causing error)
