I also added windows build so that people can help with testing also on windows. It's a static build, no need for installer, just single zipped .exe file. No dependencies.
@Johny So, you just want a low power VGA card... I did not find may new ones. I do see an ASPEED AST2400 chipset that many use for a PCIe 1x VGA card (non-gpu). It's reported to use about 2-3 watts. It costs about $30USD and ships from China. The issue I see reported with it is firmware issues. Newer systems booting with UEFI may have issues seeing the card and may need a flash update on the video card, which is a known problem.
Option 2 is to just not have a VGA display for dom0.
@cbaguzman I am not sure checking a vhd without its chain is giving much benefits
you may be able to use vhd-cli raw <vhd> <output> it will generate a raw disk of the source, you should be able to write it to /dev/null and it will fail if any block is unreadable
@irtaza9 it scans all the VDI's on the SR to see if something has changed, if there's a need for coalesce and so on.
I dont think it will be a big issue if you increase the auto-scan-interval value to lets say 5 minutes (300 seconds), but do remember, that everything regarding the VDI's on the SR will take up to 5 minutes to update, as well as triggering coalesce after removing snapshots.
