[libvirt-users] libvirt_lxc and sysfs

[pr.G]

Hello.

Is it possible to start container via libvirt_lxc without mounting /sys
inside container?

When I start container via lxc-start and do not add mount point to config, 
then /sys inside container is empty.

When I do it via virsh -c lxc:// container.xml, then 
/sys contains sysfs of the host and /sys on host becomes remounting read-only.

Am I doing something wrong or is this feature of libvirt_lxc? 

Thanks.
