openstack顯卡透傳（centos）

openstack基於centos顯卡透傳：

1、查看顯卡ID

在有雙顯卡的計算節點compute上，使用lspci -nn|grep NVIDIA命令查看顯卡設備product_id 和 vendor_id

2、控制節點配置

控制節點controller 編輯配置文件：/etc/nova/nova.conf

[scheduler]標籤下：

scheduler_driver=nova.scheduler.filter_scheduler.FilterScheduler

scheduler_available_filters=nova.scheduler.filters.all_filters

scheduler_available_filters=nova.scheduler.filters.pci_passthrough_filter.PciPassthroughFilter

scheduler_default_filters=RamFilter,ComputeFilter,AvailabilityZoneFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,PciPassthroughFilter

 [pci]標籤下

alias = {"name": "a1","product_id": "104c","vendor_id": "10de","device_type": "type-PCI"}

配置完之後重啓服務

systemctl restart openstack-nova-scheduler.service

systemctl restart openstack-nova-api.service

3、計算節點配置

計算節點compute編輯配置文件：/etc/nova/nova.conf

[pci]標籤下

alias = {"name": "a1","product_id": "104c","vendor_id": "10de","device_type": "type-PCI"}

passthrough_whitelist = {"vendor_id": "10de","product_id": "104c"}

配置完之後重啓服務

systemctl restart openstack-nova-api.service

4、UEFI配置修改

UEFI不受支持，日誌報錯uefinotsupported: uefi不受支持，需要修改源碼

安裝ovmf及win10鏡像見之前文章：https://blog.csdn.net/hutiewei2008/article/details/85986652

計算節點compute /usr/lib/python2.7/site-packages/nova/virt/libvirt/driver.py 改源碼

改成OVMF現在目錄。

DEFAULT_UEFI_LOADER_PATH = {

    "x86_64": "/usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd",

    "aarch64": "/usr/share/AAVMF/AAVMF_CODE.fd"

}

5、顯卡驅動43解決

NVIDIA驅動報錯43，解決方式。需要修改源碼。

計算節點compute /usr/lib/python2.7/site-packages/nova/virt/libvirt/driver.py 改源碼

<hyperv>

      <relaxed state='on'/>

      <vapic state='on'/>

      <spinlocks state='on' retries='8191'/>

</hyperv>

改爲

<hyperv>

      <relaxed state='on'/>

      <vapic state='on'/>

      <spinlocks state='on' retries='8191'/>

      <vendor_id state='on' value='1234567890ab'/> 

 </hyperv>

加入這一行<vendor_id state='on' value='1234567890ab'/>

重啓服務：systemctl restart openstack-nova-api.service

6、更改鏡像類型

openstack image set 8211fd9c-92c4-4f8b-be6d-6215d9be4c3b --property hw_firmware_type=uefi

openstack image set 8211fd9c-92c4-4f8b-be6d-6215d9be4c3b --property img_hide_hypervisor_id=true

openstack image set 8211fd9c-92c4-4f8b-be6d-6215d9be4c3b --property os_secure_boot=required

openstack image set 8211fd9c-92c4-4f8b-be6d-6215d9be4c3b --property hw_cpu_cores=1

7、創建實例

使用openstack的dashboard創建新實例類型passthrough，更新元數據

添加以下幾個：

pci_passthrough:alias  a1:1

img_hide_hypervisor_id  true

hw_firmware_type  uefi

添加完如下圖，

8、在雙顯卡計算節點上建立win10系統

openstack server create --flavor passthrough --image win10  --nic net-id=0e025936-a568-43fe-a32c-01f8b75472ae  --availability-zone nova:compute1:compute1 win10
