virt-install error to create instance in qemu-kvm

Question

OS: Debian 10.4 libvirtd version: 5.0.0

Hello!

I need to create a instance in qemu-kvm. With this command:

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

But he return:

[Fri, 26 Mar 2021 10:26:07 virt-install 1172] DEBUG (cli:253)   File "/usr/share/virt-manager/virt-install", line 955, in <module>

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

The br0 is ok in Debian, he ping others Ip in the physical network. I can make and receive ssh connections with the BR0 IP.

I dont understand what is the parent error:

Domain installation does not appear to have been successful.

or

ERROR (cli:254) Unable to add bridge eth0 port vnet0: Operation not supported

And how to fix them.

Thanks again!

`eth0` is a rather unlikely bridge. – berndbausch Mar 26 '21 at 11:25 — berndbausch, Mar 26 '21 at 11:25
|__ yes is unlikely bridge, the correct is br0 – CH06 Mar 26 '21 at 12:06 — CH06, Mar 26 '21 at 12:06

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.

bridge=br0 <-- br0 and not eth0. Thanks a lot! – CH06 Mar 26 '21 at 12:06
