Hi all,

I'm running 2 domUs simulataneously with multiple img partitions mounted. On starting the 3rd I got the following error:

Using config file "/etc/xen/conf/gust3.cfg".
Error: Device 769 (vbd) could not be connected. Failed to find an unused loop device.

I found this solution:

you could pass it as an option to your kernel at boot time, if you use grub, add  "max_loop=64" at the end of your kernel line, then reboot the server and look how much devices are declared in /dev/loop*

As you can see it requires to reboot the server which is not possible since it is a production server :

Can someone please give me a proposal to increase loop devices without rebooting the server ?

Thanks in advance,
