[pve-devel] [PATCH qemu-server/docs/manager v7 0/4] vIOMMU-Feature #3784

[Markus Frank <m.frank@proxmox.com>]

I was able to clarify any ambiguity regarding vIOMMU:
https://lists.gnu.org/archive/html/qemu-devel/2023-10/msg02370.html

The iommu_platform parameter could be made an optional parameter for VirtIO
devices to add more isolation (with the downside of making them less performant)
in a follow-up patch series.

qemu-server:

v7:
* changed viommu to string and added virtio-iommu implementation
* seperated "machine as property-string" patch from "feature #3784" patch
* moved format definition/parsing/printing to QemuServer::Machine
* merged test-cases into "feature #3784" patch
* removed kvm check, since it does not prevent vIOMMU from working
(only nested virtualization requires kvm & host cpu)

v6:
* added helper function for machine config validation
* replaced old standard option for "pve-qemu-machine" to new property string

v5:
* set $kvm to 1 if is_native, so that api kvm check works.

v4:
* added kvm/q35 checks in API
* reused pve-qemu-machine

v3:
* replaced old machine type with property-string with viommu-parameter

v2:
* moved viommu-parameter inside of machine_fmt and added it the new
parameter machine_properties
new Config -> machine_properties: viommu=1,etc
* check if kvm and q35 are set
