Re: [Bug] Error when running network-attach

["Paul Leiber" <paul@xxxxxxxxxxxxxxxx>]

Hi, 

you probably need to set up the bridge xenbr0 (default name) manually in Dom0. 
Please have a look at

https://xenbits.xen.org/docs/unstable/man/xl-network-configuration.5.html#bridge

and

https://wiki.xenproject.org/wiki/Network_Configuration_Examples_(Xen_4.1%2B) 

There seem to be other errors in your log which I can't diagnose.

Paul

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
Cailigang
