Qubes OS: A reasonably secure operating system

I ran Qubes on a laptop for a while. 1) It's a huge battery hog. 2) It's a real pain to run a non rolling release distro (i.e. Arch). Some dependency is going to try and upgrade itself that can't and it will brick your whole distro. Even being locked to a specific release proved a bit of a pain. It just adds a lot of complexity to your day to day operations (i.e. opening a program is a tiny bit more complicated) that turned out to be a huge drain for me.

Running an HVM with a separate kernel should alleviate those problems. Qubes is phasing out PV support anyway.

I encounter an equal amount of complexity in my KVM workstation as I did in my Qubes workstation, and more problems.

For example, lack of a secure copy/paste mechanism, meaning I must type passwords by hand to avoid every VM being exposed to the clipboard.
