The lspci -v command can be used to print information for PCI devices already installed on a system. Note that the NVIDIA Quadro 2000 is not supported, nor is the Quadro K420 card.Ĭheck vendor specification and datasheets to confirm that your hardware meets these requirements. The emulated VGA is used for pre-boot and installation and the NVIDIA GPU takes over when the NVIDIA graphics drivers are loaded. Currently up to two GPUs may be attached to a virtual machine in addition to one of the standard, emulated VGA interfaces. For example, if a switch does not support ACS, all devices behind that switch share the same IOMMU group, and can only be assigned to the same virtual machine.įor GPU support, Red Hat Enterprise Linux 8 supports PCI device assignment of PCIe-based NVIDIA K-Series Quadro (model 2000 series or higher), GRID, and Tesla as non-VGA graphics devices. PCIe devices must support ACS or ACS-equivalent capability.Īll PCIe switches and bridges between the PCIe device and the root port should support ACS. IBM POWER8 supports IOMMU by default.ĬPU root ports used must support ACS or ACS-equivalent capability. However, use the default allocations, which use more storage space.ĬPU must support IOMMU (for example, VT-d or AMD-Vi). The minimum storage requirements for host installation are listed below. The storage requirements for Red Hat Enterprise Linux hosts vary based on the amount of disk space used by their existing configuration but are expected to be greater than those of RHVH. The minimum storage requirements of RHVH are documented in this section. Using network storage might result in a performance downgrade. If RHVH boots from SAN storage and loses connectivity, the files become read-only until network connectivity restores. Adding a drop-in multipath configuration file can help address losses in network connectivity. Booting from network storage can result in a freeze if there is a network disconnect. Red Hat Virtualization Host (RHVH) can boot with one, some, or all of its default allocations in network storage. Hosts require storage to store configuration, logs, kernel dumps, and for use as swap space. Infrastructure Considerations"Ĭollapse section "3.5.
