[libvirt-users] snapshot-create fails with "error: Failed to open file '(null)': Bad address"

[Thomas Stein]

Hello.

I'm not able to create a snapshot for none of my vm's running on a 
particular node. And i have absolut no idea where to look to solve this. 
Someone can point me to the right direction?
