It's not in the interest of either side.

Ukraine is not going to accept Russian territorial demands and Russia is not going to give up what it has taken. Likewise Ukraine is not going to accept any demands Russia wants to impose on their military and Russia is not going to allow the Ukrainian military to continue building up like it is.

A ceasefire might be arranged but that does not solve any of these issues so hostilities would break out later on again anyway, both sides would simply use the ceasefire to give them time to build up strength.
At best we could get a situation like in North Korea where the ceasefire becomes the de facto status quo but that might be wishing for too much in this situation.
