In Vietnam, he is a respected figure, generally considered a founding father of modern Vietnam. He commands the kind of respect similar to that of Queen Elizabeth II in the UK, George Washington and the founding fathers in the US, King Juan Carlos I in the 90s Spain, Mahatma Gandhi in India, or even Mao Zedong in China. I guess every country needs a symbolic figure to bring the people together through tough times and Ho Chi Minh was made to play this role and he certainly stayed in the heart of the people for a very long time.
We call him "Uncle Ho". People in the country look up to him as a moral authority. When we were kids, we were taught his 5 teachings for children, that includes values not much different from what you have in a Western society: patriotism, hard working, cooperation, discipline, humbleness, integrity, bravery, and hygiene (yes, hygiene! It was important in a post-war, poverty ridden Vietnam).
In school we learnt about his life, his adventures around the world to find a way to save the country, his fluency in multiple languages, meetings with world leaders to negotiate alliance, his humble and frugal life. He is like a cool grandfather that you always wish to have.
If you have a chance to go to an international sports games where the Vietnam national team plays (especially soccer, we are crazy about soccer), listen and you will hear the loud singing and chanting from the stalls. It goes like this "Vietnam.... Ho Chi Minh...". No-one decided that this is the song we should sing to rally our sportsmen and women. No-one knows how it started. Some time in the past, someone sang it at a game and it caught on. And then everyone was singing it. The people just found that this is the song that connects all of their hearts.
