ncm, I think this may be an error of interpretation, the coral turns white when it dies, I mean when the organism dies. They form a symbiosis with alguaes and those give the color, white coral appears when the animal dies, you just have the skeletton left. White coral (with a few exceptions which are naturally white) is just like the bones left from a dead animal, it may result from increased acidity of water, but also from any other deadly condition. For example when overheating, if water temp reaches around 42 degrees, the coral rejects the alguae then dies, it can be quite dramatic because suddenly very large areas whithen suddenly, it's all dead and will take maybe half a century to get back in proper shape :-(
libvirt development progresses rapidly, as the traffic on the list can testify, we now have native secure remote operations, and there is ongoing work to add OpenVZ support. I hope to increase coverage of more virtualization engine, so far it looks good, we don't seems to have serious API design problems.
I made a new release 0.1.9 last week with some bug fixes and portability improvements.
