Re: [Xen-users] Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

[headhunter_unit23 <atatut@xxxxxxxxx>]

Hi Olivier,

I had this problem with Xen 2.6.18-r12 on Gentoo 2.6.31-r6 with udev 146-r1

xm create /PATH/TO/MY/VM/CONF 

gives after a while: 

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

I had to package.mask the gentoo kernel and udev latest versions and force
gentoo to install the following versions:

- linux-2.6.29-gentoo-r5
- udev-141

before I compile the xen kernel 2.6.18-r12

I found no other solutions than the above; kernel and udev downgrade, which
forced me to reinstall the whole server.

The first install with Gentoo 2.6.31-r6 with udev 146-r1 versions gave me:

* Mounting proc at /proc 
* Mounting sysfs at /sys 
* Your kernel is too old to work with this version of udev. 
* Current udev only supports Linux kernel 2.6.25 and newer. 

at boot time and that's what gave me the hint to downgrade the kernel and
udev versions.

If you don't need anything inside the latest kernel, then I suggest you
downgrade your kernel and go back to the "working" kernel version.

Hope this helps,

Cheers,

headhunter
