[lxc-users] ubuntu containers on fedora host

[Király, István]

>> My first suggestion would be "use ubuntu host, it should just work" :)

I use fedora since fedora core 1, and wrote my app, srvctl - with a lot of
code for it, and move familiar within it. Back in my University days,
Gentoo was the most hyped distro, now Ubuntu seems to be, but I'm really
happy with Fedora. Just want to supply my users with the option for ubuntu,
.. .)

>> lxc-start -F
Aha, here it hangs for 120 seconds.

No idead what metadata is necessary. ...

>> Also, why did you use ubuntu cloud template? The download template
(where you can choose various distros and versions) should be more suitable
for most purposes.

I know you guys work on that a lot, but for me it seems that the templates
are mostly unmaintained, and don't work so well - at least I got the
feeling with using the fedora template for a while ... so I stopped using
them and make the rootfs on my own, by extracting the relevant code from
the templates and integrating the relevant parts to my app.
Didn't check yet for non-cloud versions, as I though that the cloud version
should be exactly what I need, as I run a sort of cloud ... but I see now
there might be some EC2 specific, or openstack specific code in it, that is
less LXC friendly .. I'll take a look at the ubuntu template.


Thank you, for your reply!
