在qemu-kvm中创建实例的安装错误

Question

操作系统: Debian 10.4 libvirtd版本: 5.0.0

你好!

我需要在qemu中创建一个实例。使用此命令：

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

但他回来了：

  virsh --connect qemu:///system start test01
otherwise, please restart your installation.

br0在Debian，贺平在物理网络中其他叶问。我可以使用BR0 IP建立和接收ssh连接。

我不明白父母的错误是什么：

Domain installation does not appear to have been successful.

或

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！

Answer 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>，即.--network bridge=br0。
