[lxc-users] Error on nested LXC-ibvirt container

[CDR]

Dear Friends
I defined a new network for libvirtd, after the default network gave
me the same error:

virsh net-start nat
error: Failed to start network nat
error: Unable to set bridge nat0 forward_delay: Read-only file system

Is there any work around? I need to have two levels of nested containers.
Rest assured that the file system is not read-only.
