Re: [Xen-users] two bridges with xen 3.2.0

[Jordi Moles <jordi@xxxxxxxxx>]

Hi, i tried something new....

i read somewhere that the problem now was that i had not installed 
hotplug on my debian.
i did this:

********

# apt-get install hotplug

The thing is that it removed 2 different paquets, "initramfs-tools" and 
"udev",  which i don't if xen needs.
anyway... after that, i keep getting the same error;

**********
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.
**********

any idea?
