That sucks...thx both. @both - which ACS version do you use (and encounter such issues?)
Ubuntu comes with a whole another set of issues (I was losing my nerves around very idiotic things, last time a week ago...) - though most can be managed with some workarounds. But yes, Qemu/libvirt should be better with Ubuntu - free of RedHat s$^%tty business politics - i.e. in CentOS 6.x you were able to live migrate VM WITH all the volumes to another host/storage. On CentOS 7 you can't do that any more, unless you are using qemu-kvm-ev (but not the regular one from the SIG CentOS repo, you need the one from the oVirt project) I'm just trying to understand if this is happening also on i.e. ACS 4.11 - so to stop digging around the problem (and assume it's purely CentOS which is broken - why all great things need to come to an end...damn it) (well I could also test same ACS code on Ubuntu and see if no issues there with live migrations..)
