This is what I was doing to create a venv in Python 3.4 on Ubuntu 14.04.3 LTS until last week:
» pyvenv-3.4 --without-pip venv
I was doing that because of this. But since yesterday:
» pyvenv-3.4 --without-pip venv
The program 'pyvenv-3.4' is currently not installed. You can install it by typing:
sudo apt-get install python3.4
python3.4 is definitely installed:
» python3.4 --version
Python 3.4.3
I have probably done an apt-upgrade recently, but ... why has pyvenv-3.4 disappeared?
venv is a built-in module in Python 3. You can always call it via the -m <module> call stack. So for your example:
python3 -m venv --without-pip venv
As for where it's gone, 3.4.0 (in trusty-updates and trusty-security) ships the script. However 3.4.3 in trusty-proposed does not. This may explain why yours has gone missing.
You can still use it with python3 -m venv ... so it's not that important.
If you're wondering how you ended up on 3.4.3, it was SRUd into trusty-updates back in September and pulled very recently after it was found to break several things. This should be fixed and re-released in short order. Follow that bug report for updates.
dpkg -L python3.4 | grep venv on my system doesn't show it in the file listing. That suggests that it's been removed in later versions. I'm on 3.4.3-1ubuntu1 from trusty-proposed.

It now appears in Synaptic Package Manager under "installed - local or obsolete" along with all its dependencies. In fact, I think this is worth its own question. – Organic Marble Oct 7 '15 at 15:46
