错误提示,
urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)>
解决办法:

1、进入SHELL命令窗口下
~# nano /etc/default/grub
修改行“GRUB_CMDLINE_LINUX_DEFAULT="quiet",
使其为“GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on",
如果是amd cpu请改为:GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on" 。
2、更新grud
~# update-grub
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-6.2.16-3-pve
Found initrd image: /boot/initrd.img-6.2.16-3-pve
Found memtest86+x64 image: /boot/memtest86+x64.bin
done
3、新增模块。修改文件/etc/modules,加入如下的行
~# nano /etc/modules
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
4、重启系统
~#reboot
5、可以在PVE WEB界面添加需要直通的PCI设备了。
