These should be handled by the patch in Comment 2

today I've installed rhev-hypervisor-advanced-6.4-20130410.0.el6ev.noarch.rpm

it was an update to rhev-hypervisor-advanced-6.4-20130321.0.el6ev.noarch and several older rhevh builds

it resulted in wrong symlink

lrwxrwxrwx. 1 root root        66 Apr 11 13:58 rhevh-adv-latest-6.iso -> /usr/share/rhev-hypervisor-advanced/rhevh-6.4-20130410.0.el6ev.iso

which should be
lrwxrwxrwx. 1 root root        85 Apr 11 14:59 rhevh-adv-latest-6.iso -> /usr/share/rhev-hypervisor-advanced/rhev-hypervisor-advanced-6.4-20130410.0.el6ev.iso

please obsolete old broken builds (like 6.4-20130321.0)

when I cleaned all rhev-hypervisor packages and installed   rhev-hypervisor-advanced-6.4-20130410.0.el6ev.noarch.rpm again, link was created properly

obsoleting won't work, despite my suggestion that it would.  Because of the ability to install rhev-hypervisor-advanced side-by-side, obsoleting an old build results in a yum error because it wants to keep the old version but also remove it.

The only way to really fix this is to remove all old versions of rhev-hypervisor-advanced and then install only 6.4-20130410.0 or newer.  Once you're in a state that has only 20130410.0 or newer, then things should work as expected.

The issue is that there is a bug in the %postun script of the builds before 20130410.0.  That bug is fixed, but for yum transactions that remove one of the broken builds, the symlinks end up broken.

As a side note, even an obsolete would not solve this problem if it worked correctly.  The postun script in the broken rpm runs after the post script in the new rpm.

Adding known issue notes with workarounds.  

Nothing else I can do to fix this that I can see.

Moving back to ON_QA for verification that other symlinks are correct and upgrades starting with 20130410.0 are correct

*** Bug 961179 has been marked as a duplicate of this bug. ***

This bug refers to the rhev-hypevisor-advanced component.  This component was supposed to be introduced in RHEV 3.2.  It was later decided to drop the inclusion of this component in favor of the existing rhev-hypervisor6 component in RHEL.  

Because we're dropping the component, this bug is not valid any longer.  It only ever appeared in the rhev-hypervisor-advanced component.

Removing requires_doc_text? flag as this is not relevant to the RHEV 3.3 release notes.
