Steve Kemp's Blog Writings relating to Debian & Free Software

Things have settled down nicely

I've now completed all my KVM migrations. Moving my personal virtual machines from one host to another.

There were a few niggles, for example I didn't have a working IPv6 allocation at the time I moved things so I had to set that up post-migration.

I've also joined each of the hosts into a VPN which makes cross-guest communication secure and simple.

Finally I've overhauled my firewalls and service lists.

I installed a couple of extra guests, using libvirt and booting from the Debian ISO. The Debian installer continues to impress, though it did make me think I should overhaul my PXE setup at home.

It wouldn't be hard to have a Raspberry PI running as a TFTP + DHCP server. You could plug it into a network, reboot your desktop, and then have it boot into the imager. At the moment I run DHCP + TFTPD + etc on my main desktop, and that allows me to reimage any of the hosts in the flat easily, except itself obviously.

The last time I reinstalled this system I had to reconfigure DHCP + PXE + TFTP on another host. I think the next time I need to reinstall any system I'll "waste" an SD-card on an image-server host.

Finally I've recently read the Rick Cook Wizardy Series:

  • Geeky developer gets transferred to a typical fantasy land:
    • Where magic works/exists.
    • There are dragons.
    • He writes a magic-compiler using FORTH to build primitives into bigger spells.

Fun idea. Horrible puns. Some of the books were too long, or left plot elements dangling, but on average they were more good than bad. Albeit a little predictable and "simple".
