Dear colleagues, I've just realized that my KVM-hosts are running CentOS-6 whilst it's recommended to use CentOS-7 with the new versions of ACS. Everything seems to be fine (some of these hosts are working for a few years), hosts are working and things are great, but I'd like to ask a couple of questions. Here they are.
(1) How high is the chance of the next version of ACS (4.10 or 4.11) will be incompatible with CentOS-6? Should I worry about that and consider upgrading to CentOS-7 immediately? (2) What ACS features I'm missing because of that? I suppose that I'll be disappointed if I try to limit a VM's IO-consumption, just because old good QEMU-0.9 won't support it. Am I right? Are there other things that are worth of upgraging to CentOS-7? Thank you very much in advance for your replies! -- V.Melnik
