Is a virtual machine totally safe?

Sounds like unnecessary risk to me. How do you plan to get the virus into the VM, without accidentally infecting yourself while doing so? Do you know for certain the virus isn't designed to break out of a virtual environment? Also make sure it's not a boot sector virus or anything else designed to infect firmware.
At the very least, I'd use a Linux based host, if you're certain the virus you're dealing with is only designed for Windows. Then make sure to remove the network from the virtual machine before running anything on it. Take a snapshot before infection and roll back to the snapshot afterwards.
If you want extra security, physically remove the host from the network. Wipe the entire machine from a read-only bootable USB stick when you're done. Even then there's no 100% security unless you know exactly what type of virus you're dealing with and what its capabilities are.
