Hi, all. When I executing virsh to connect to openvz I get the following: [root@localhost ~]# virsh -c openvz:///system libvir: QEMU error : cannot create bridge 'virbr0' : File exists Failed to autostart network 'default': cannot create bridge 'virbr0' : File existsWelcome to virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit virsh # ... But I didn't want to connect to QEMU... Anton
