I use Myth in an unprivileged LXC container on a Ubuntu Trusty/14.04
host ... it works really really well and has been stable for 18 months
or so.
Some key points ...
- I use USB tuners, so needed to pass them thru from the host, wasn't
too hard in the end
- All screen access is via X2GO
- Needed to access setup via ssh from host "ssh -X my-id at 192.168.x.yyy
mythtv-setup.real"
- Set max CPU and RAM limits
- Supports 2 main clients and 4 tuners
- The host also doubles as the file server
I have various KVM VMs .... but they're much more resource intensive
albeit with higher security
On a middle of the road 4 core haswell cpu (no hyperthreading) with
16GB I run
- 4 LXC containers ... permanently
- 1 Heavy Windows gaming PC, with GPU passhrough, occasionally at full 2
cpu performance (whilst the LXC machines are all ticking away in the
background)
- 1 medium weight KVM machine occasionally
various other KVM machines very occasionally for special purposes
The point being -
- with LXC you can run very high VM densities on relatively modest
processors
- Myth can run very successfully inside an LXC container
- KVM offers better security & control at the expense of higher resource
utilisation
