slackrepo is indeed interesting. I can probably run this in a Docker container running pristine Slackware (or hack it so that it can spawn one for builds on its own!)

Hi,

Just two quick random notes.

1) You can achieve interesting results using QEMU disk image compression:
Code:
9.4G Aug 19 01:23 slackware64-14.2-sbo.base.qcow2
3.2G Aug 21 02:43 slackware64-14.2-sbo.comp.qcow2
428M Aug 23 06:11 slackware64-14.2-sbo.diff.qcow2
 37G Aug 14 01:10 windows64-7.base.qcow2
 15G Aug 20 00:54 windows64-7.comp.qcow2
170M Aug 23 05:51 windows64-7.diff.qcow2
*.base.qcow2 is the image before compression and *.comp.qcow2 after compression.
*.diff.qcow2 is backing_file, when VM runs, all the disk writes go to this image and not to the compressed one.
I haven't noticed slowdowns using compressed images, and that's cool :-)

2) Accessing libvirt managed VM using host name resolution:
If you want to access your virtual machines by hostname, you have to read about Libvirt NSS module.
I spent a lot of hours trying to figure out how to do it using other means, but it was that simple :-/

Cheers.
