I have two VMs on one node. The both use PCI devices, but different. And they can't run at the same time together.
Error from first:
Error from second.
those PCI passthroughed devices are video card and LSI SAS controller. They work perfectly in one started VM, even if I pass them both there. But doesn't in different VMs.
They both trying to access "/dev/vfio/1", though PCIe devices are different, so why? And how can I change it?
their configurations respectively:
