1. Grab a minimal distribution ISO image and download it to your oVirt ISO domain

CentOS 7: CentOS-7-x86_64-Minimal-.....iso) from http://isoredirect.centos.org/centos/7/isos/x86_64/

Ubuntu: mini.iso from http://cdimage.ubuntu.com/netboot/

2. Create a virtual machine (512MB RAM is enough at first) and boot it from the downloaded ISO image

Don't forget to assign a network interface (and a IP address or a working DHCP server).

Warning: Things change a lot around Ceph. The guide below might not work with the current release.

Following Laurent Barble guide about mapping rbd images without installing ceph-common I've played with the systemd + fstab on CentOS7 (other distributions with kmod-rbd and systemd might also support this method). Systemd adds some interesting new features to regular fstab entries to automount filesystems.

We have an Acer Aspire One (Intel Atom with 1GB RAM) which was running Windows XP. Since it is no longer supported by MS I've spent some time to find a replacement.

For this hardware MS has no viable alternative I know of. There are, however, several Linux distributions that aim old netbook hardware.

I've checked these:

After dropping Fedora I switched to Ubuntu Gnome Desktop. It works pretty well, even my kids can use it.
This page contains some random tips about it. See my other pages about Gnome and Fedora on Lenovo.

I've been using Fedora for a couple of years now. I was kind of happy with it. I liked Gnome3 and I could handle the minor annoyances. It was stable enough to serve as my work, travel and home opsys.

As F16 reaches its EOL, I installed F18 on a clean PC. Well....

It is a disaster

The installer tries to be simple and intuitive but it is oversimplfied and not handy at all.
It crashed two times before I managed to install Fedora. F16 installed on the same PC without any problems.

This a set of random tips, suggested settings and programs I've collected during the setup of Fedora on a Lenovo T420 notebook.
