操作系统：Debian 10.4 libvirtd 版本：5.0.0
你好！
我需要在 qemu-kvm 中创建一个实例。使用以下命令：
virt-install --connect qemu:///system --virt-type kvm --name test01 --ram=2048 --vcpus=2 --disk /opt/test01/test01.img,bus=virtio,size=10 --pxe --boot uefi --noautoconsole --graphics none --hvm --network bridge:eth0 --description "Test VM with w2k16" --os-type=windows --debug
但他回答说：

If it was, you can restart your domain by running:
virsh --connect qemu:///system start test01
otherwise, please restart your installation.

Debian 中的 br0 正常，他可以 ping 物理网络中的其他 IP。我可以使用 BR0 IP 建立和接收 ssh 连接。
我不明白父错误是什么：
Domain installation does not appear to have been successful.
或者
ERROR (cli:254) Unable to add bridge eth0 port vnet0: Operation not supported
以及如何修复它们。
再次感谢！
答案1
bridge=BRIDGE
Connect to a bridge device in the host called BRIDGE.
Use this option if the host has static networking config & the guest requires
full outbound and inbound connectivity to/from the LAN.
Also use this if live migration will be used with this guest.
--network bridge=<bridge_iface_not_phys_iface>， IE。--network bridge=br0。
