There´s your problem. You should always make sure that your hosts are at
the same level of functionality as the engine. Breakage like this isn´t
nice, but you should have paid more close attention to the upgrade
process.

Having a gazillion different "release" packages floating around isn´t
helping, and installing them leaves ".repo" files behind that can mess
it all up, but that´s the way it is. That particular issue was just
about to annoy me enough to bug report, but then I noticed that it
already was:)

Thanks Bob:)

> So the 3.3.5 web engine complained that it wasn't the appropriated vdsm. Then I decided to upgrade engine to 3.4.0 el6 bit this time none of my 6 hosts get successfully activated and the error message is that host emulated is not the good one. I updated all of them to 6.5 with or without the official qemu it is the same. I remember I changed the 3.3 cluster compatibility for 3.4 but I can't rolling back to 3.3 compatibility (tells me it can't "decrease") What can I do now? Fortunately I saved the initial 3.2 webadmin image so that I can revert back to my to my 3.2 functionnal webadmin.

A little blurry there, but you say that Engine is now 3.4.0? How about
making sure to add the newest repo for 3.4.1 in both Engine and Hosts?

And take extra care of any old repo's you may have and which of them
really are enabled. Then "yum upgrade" the hosts, restart "vdsmd" and
see if it makes any difference?
