Re: A light VM for testing Xen.

[Jason Long <hack3rcon@xxxxxxxxx>]

Thank you.
I used "xl create /etc/xen/test.cfg" and got below error:

$ sudo xl create /etc/xen/test.cfg
Parsing config from /etc/xen/test.cfg
libxl: error: libxl_exec.c:117:libxl_report_child_exitstatus: 
/etc/xen/scripts/vif-bridge online [176788] exited with error status 1

destroy guest
libxl: error: libxl_domain.c:920:domain_destroy_cb: Domain 3:Destruction of 
domain failed


I changed config as below:

vif=['10.0.0.60,script=vif-route']

And added below lines to "/etc/xen/xend-config.sxp" file:
(network-script network-route)
(vif-script vif-route)

Then commented out below line in "xl.conf" file:
vif.default.script="vif-route"

But, I got below error:

$ sudo xl create /etc/xen/test.cfg
Parsing config from /etc/xen/test.cfg
libxl: error: libxl_exec.c:117:libxl_report_child_exitstatus:

libxl: error: libxl_domain.c:920:domain_destroy_cb: Domain 5:Destruction of

How can I solve it?

I think that you need to read the documentation about setup the bridge, and the 
xl tool... Those are prerequisite for the commands that I send to you
