Essentially, what the error tells you is that KVM timed out on start. I see that you have PCI pass-through in the command line. Try it without the PCI devices. If VM starts, review the passthrough guides, post your configuration (qm config [id]), review journalctl and dmesg,
If you continue having trouble, post more comprehensive description of your setup.

Good luck

Thanks！ I was able to start the VM after removing the PCI device.

After following various tutorials to enable hardware passthrough, I am unable to start the VM.
