Hi,

I have a problem with an automatic yum vdsm upgrade  (4.13 to 4.14)  on ovirt 3.3  : Host x.x.x.x is installed with VDSM version (4.14) and cannot join cluster Default which is compatible with VDSM versions [4.13,4.9,4.11,4.12,4.10].

I am searching the solution and one of them (from bz Bug 1083008 ) points to gerrit site(http://gerrit.ovirt.org/#/c/23456/)

I do not have any experience in solving bugs, neither bz, gerrit, github....  
How to initialize in this world and solve the ovirt problem ?

another thing : does downgrade or remove vdms package excludes the installed virtual machines ?
