AMD, then processor type is AMD.
S1102, when processor be Intel processor when, by intel_iommu=on write kernel in；When processor is
During AMD processors, by iommu=1 write-in kernels.
Specifically, in/etc/default/grub files be the row that starts with GRUB_CMDLINE_LINUX, for
Intel processor writes intel_iommu=on, and iommu=1 is write for AMD processors.
S120, judge whether the virtualization system supports virtualization, if so, then performing step S130；If not supporting, it is
System quotes the information of " current system does not support IOMMU ".
Specifically, for ADM processors, order " dmesg | grep AMD-Vi " is performed, if output information includes
AMD-Vi, then it represents that virtualization system has been switched on IOMMU functions, for Intel processor, perform order " dmesg | grep-
E DMAR-e IOMMU ", if output information includes DMAR and IOMMU, then it represents that virtualization system has supported IOMMU
Function, can distribute physical network card and be used to virtual machine is exclusive, if not having the information output of correlation, system in output information
Quote " current system does not support IOMMU ".
Wherein, there is relevant information to export if performing mentioned order, and carried out the exclusive distribution of physical network card, it is empty opening
During plan machine, virtualization system quotes " please ensure all devices within the iommu_group
Are bound to their vfio bus driver ", then show that hardware is not support that network interface card leads directly to, and system quotes " thing
Reason machine hardware does not support that network interface card leads directly to function ".
S130, the network interface card parameter information for obtaining physical network card；
Specifically, by taking the type physical network cards of Intel 82576 as an example, using order " ethtool-i physical network cards title ", obtaining
Take the domain of physical network card, bus, slot and function parameter, wherein, the bus message of the network interface card for getting is
0000:06:00.1, i.e. domain are hexadecimal number 0, and No. bus is hexadecimal number 06, and No. slot is hexadecimal number 00,
No. function is hexadecimal number 1, and then is configured according to the network interface card parameter information for obtaining.
S140, by the configuration file of the straight-through default virtual machine of configuration information write-in of network interface card, the network interface card is straight-through to match somebody with somebody confidence
Breath includes the network interface card parameter information.
