libvirt-guests is blacklisted from the RHEV-H image. In order to fix this, we need to do one of the following: 1. don't blacklist the service, but let vdsm disable it (bz moves to RHEL 6 ovirt-node) 2. have the vdsm plugin package essentially hack the script so that it removes libvirt-guests from the conflicting services (move to ovirt-node-plugin-vdsm component in RHEV) 3. have vdsm not throw a stack trace if a service does not exist (move to vdsm component in RHEV) #1 is easy, but seems like an odd way to approach this (add service just so we can blacklist it) #2 is slightly more difficult but doable. It is very hackish, though, and could be susceptible to breaking in the future due to the way we would have to do this. It would likely be a sed script to parse specific files to remove references to libvirt-guests #3 seems like the *right* solution to me. It protects us in the future in the case that services get removed or are not included automatically. (In reply to Mike Burns from comment #1) > libvirt-guests is blacklisted from the RHEV-H image.

Federico any other suggestion? moving to vdsm, please move if we decide on a different approach.

Discussed with Zhou Zheng Sheng about the upstream code and this report won't affect it. A solution can be the downstream patch only as follow (verified).

Agree to this solution (only for conflicting services part). Keep in mind that the code is different in master branch, should be fixed also there *** Bug 1007362 has been marked as a duplicate of this bug. *** fixed in is15 - version rhev-hypervisor6-6.5-20130917.0.el6ev.noarch.rpm verified RHEV Hypervisor - 6.5 - 20131011.0.el6 This bug is currently attached to errata RHBA-2013:15291.
