Re: "INTx fd" busy error on VM startup at boot, subsequent startup okay
...he same problem (on CentOS 7) with a custom data acquisition PCI card. It seems like the solution might have something to do with delaying the start of libvirtd in systemd until the PCI card (or vfio?) is ready, but I don’t know how to do that. Can anyone else offer assistance?
My output:
