Also consider testing if system gzip supports --rsyncable and using that in script, might greatly speed up rsyncs.

How to create a KVM template in Proxmox VE

Wed, 10/31/2012 - 19:01 — dnaeon

Probably this is something that most people working with Proxmox VE have stumbled upon.

In Proxmox VE you can only use (at least for now) OpenVZ templates. If you are intrested in running Proxmox VE with KVM (as I was), then you will be surprised that the only supported templates are for OpenVZ.

Here are the instructions to filter out just the photos we picked.

I'm attaching a file alex_suzanne_picks.lrsmcol that defines a LightRoom Smart Collection Settings that filters out just the photos we want. This file is identical to the following, but includes all the photos:

s = {
  id = "D7B14054-AE5E-4FC8-8E16-FC0EAA9B9581",
  internalName = "Alex_Suzanne_Picks,
  title = "Alex_Suzanne_Picks",
 type = "LibrarySmartCollection",

My Vagrant Ubuntu VM just died while running a memory intensive command.

Its output just says "Killed".

vim /var/log/syslog confirms that the machine ran out swap and the process was killed.

free -m shows we have 768M (or so) swap space.

sudo swapon -s shows that we have a single swap partition at /dev/mapper/precise64-swap_1

I googled around, especially with site:news.ycombinator.com for backup recommendations. Here are notes on the top hits.
