Vhost user sockets are shared between qemu and ovs. Currently, we are patching ovs service file to make ovs run as qemu user. In order to avoid it, a new group 'hugetlbfs' has been introduced, which will be used by ovs and qemu. This patch allows the users to configure the group setting for qemu.conf file.
