Hi，ALL！ I recently tried to assign nvidia's graphics card virtualization to my virtual machine, and I've made it to the last step of assigning the virtual device to the virtual machine. But I'm having a problem with the <alias name='hostdev0'/> statement disappearing. At first I thought that the statement did not conform to the xml syntax, until I found the following post in the forum, I didn't realize it was a bug. The owner of this post seems to have circumvented the problem of disappearing alias names by other means. But for me, I can't solve the problem the same way. Is there any solution to this problem now？ Thanks for the support! The following is my original xml for reference： <hostdev mode='subsystem' type='mdev' managed='no' model='vfio-pci' display='off'> <source> <address uuid='xxxxxxxxxxxxxxxxxxx'/> </source> <alias name='hostdev0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </hostdev> <qemu:commandline> <qemu:arg value='-set'/> <qemu:arg value='device.hostdev0.x-pci-vendor-id=0x10DE'/> <qemu:arg value='-set'/> <qemu:arg value='device.hostdev0.x-pci-device-id=0x1c30'/> <qemu:arg value='-set'/> <qemu:arg value='device.hostdev0.x-pci-sub-vendor-id=0x10DE'/> <qemu:arg value='-set'/> <qemu:arg value='device.hostdev0.x-pci-sub-device-id=0x1c30'/> <qemu:arg value='-set'/> <qemu:arg value='device.hostdev0.driver=vfio-pci-nohotplug'/> <qemu:arg value='-uuid'/> <qemu:arg value='xxxxxxxxxxxxxxxxxxx'/> </qemu:commandline>

我有一块nvidia p4显卡。前几天看见了论坛里有个大佬分享了unraid上的驱动，就想尝试下之前看到的虚拟化显卡方案。 之后我按照RSG大佬的教程 https://www.lxg2016.com/55831.html ，进行了尝试。 进行到最后一步将虚拟化显卡插入虚拟机xml文件时， <hostdev mode='subsystem' type='mdev' managed='no' model='vfio-pci' display='off'> <source> <address uuid='9d046154-52a6-4c84-88a1-b5ae0a621a10'/> </source> <alias name='hostdev0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </hostdev> 此处的 <alias name='hostdev0'/> 语句无法保存，点击更新后该语句会自动消失，导致后面的语句无法调用hostdev0这个设备。 unraid版本: 6.11.5 稳定版 如果各位大佬有其他攻略可做参考，或者能解决虚拟机配置无法更新的问题都可以。 非常感谢！

The first problem is that after I restart my unraid, I find that the web access of the unraid is denied (including port 80 and port 8080). But I can use ssh to get to unraid. By connecting the display, I found that the unraid stopped at the last step of startup--starting samba. After repeated attempts, I found that the problem was solved as long as I closed the access to the ipv6 address of the management port. My ipv6 environment has not been configured, so I cannot access the Internet through ipv6. I want to confirm whether this problem is caused by the inability of ipv6 to access the network. The second problem is that after I update the hardware, there is a pcie network card that I often use, and the interface shows that it is shut down (not active). Although I can see the interface in unraid, I cannot configure it nor find the NIC in the interface rules. Rebooting didn't fix the problem either. Finally, I tried to re-plug the pcie network card and it returned to normal. My question for this problem is if it is because of my pcie contact problem, then why can I see the interface. If there is no problem with the pcie contact, then why am I able to configure it after replugging. English is not my native language, if there are sentences that you cannot understand, please forgive me and point them out, and I will explain in more detail. Thank you very much for your assistance.
