Hi,
Currently, we need to assign the iommu group to guests manually.
It needs to know the groups information.
I think we can add some iommu group commands to provide users
groups information.
I can think of these commands as the following:
#virsh group-list <--active>
* list all the groups in the system with VFIO
* --active: list the active groups which have been used by guests.
#virsh group-devs <groupnum>
* list the devices in the group.
*If groupnum is not specified, it will list every groups' devices.
# virsh group-dumpxml <groupnum>
* dump the group's xml configuration.
dumxml file for example:
<iommuGroup number='1'>
<address domain='0x0001' bus='0x40' slot='0x00' function='0x0'/>
<address domain='0x0001' bus='0x40' slot='0x00' function='0x1'/>
</iommuGroup>
This information can also be got by #nodedev-dumpxml <device>
But users still can't know all the groups and the devices in the group
directly.
Any suggestions?
I want to add iommu symbol to the commands name, but it's too long.
Thanks
Li Zhang
