<p class="MsoNormal">Hey Mike, did you ever have any success figuring out this issue? I am having the 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?<o:p></o:p></p>
