how bind Dummy network interface od alias ip an LXC guest without bridge?

Yes, this is possible using the “IPVLAN” virtual network interface driver. It differs from the MACVLAN driver you may already know in that it uses the same MAC address for all virtual interfaces on a master interface, just like multiple IP addresses directly on the master interface would.

On Debian, I use it like this:

auto ipvl-main
iface ipvl-main inet manual
   pre-up ip link add link eth0 name ipvl-main type ipvlan mode l2
   post-down ip link delete ipvl-main

In LXC, the corresponding configuration looks like this:

lxc.net.1.type = phys
lxc.net.1.link = ipvl-main
lxc.net.1.ipv4.address = 192.0.2.4/26
lxc.net.1.ipv4.gateway = 192.0.2.1
lxc.net.1.ipv6.address = 2001:db8:10b:2893::3/128
lxc.net.1.ipv6.gateway = fe80::1

Very straightforward. If the network namespace eats the network interface (for example due to lxc-start errors) you’ll simply have to recreate it.
