[Bug] Error when running network-attach

["蔡力刚" <cai_ligang@xxxxxxxxxxxxxxx>]

Hi,

When I try to add a network with xl network-attach command,

the log show some errors:

root@RK3588:/mnt# xl network-attach 0

what does vif-bridge exited with error status 1 mean?

"Could not find bridge device xenbr0", is that means I have to create a xenbr0?How to create?

I create a domu with the config below:

kernel = "/media/sdcard0/domu-Image"
memory = 1024
name = "guest1"
vcpus = 2
serial="pty"
vif = ['']
disk = [ 'phy:/dev/mmcblk2p2,xvda,w' ]
extra = 'console=hvc0 root=/dev/xvda rw clk_ignore_unused'

There also has the same error log above, and domu bring up failed.

If delete vif option. domu can bring up. and using network-attach create a network.

The network can work, dom0 and domu can ping each other successfully.

But the network type seems is NAT, How can I set up a bridged networking ?

Best regards
