I've got a Gigabyte motherboard with 7 R9-280's in it (using USB risers)
My thought was to install ESXi so that I could move GPU's between VMs as needed. ESXi sees them all, but can only assign 4 cards (8 PCI devices) to a VM, so isn't going to be a good platform for me.
I then tried using Ubuntu, but that distro only seems to see the GPU's on one PCI bus (4 cards).
Has anyone had a similar experience? Do other distro's seem to deal better with multiple PCI busses?
