hi,
I install xen 3.0 on our production sites servers and when i try to
create a domainU I get the following error message:
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.
I search in the Internet but I don't found anything which solve my issue.
First of all, I have used the default scripts network-bridge and
vif-bridge but the bridge did not mount during reboot so I've tried
to use the network script for xen 2.0.7 and this solve my first
issue.
So now, my problem is to mount the vif interface during domainU
creation and I have no idea why this error message happened. It seems
to be generic and I don't understand why my device is "busy" as we can
see in the following logs...
Our servers are on linux LFS OS, I suspect the network-bridge script
not being compliant with our network scripts (we have not ifup
command). I can easily solve this problem but I don't think the vif
interfaces will mount after that.
Here is the output of the script xend-debug.log:
