[Users] Support by Scientific linux?

If you would like to use SL 6.2 as a node:
- Change the contents of /etc/redhat-release to "Red Hat Enterprise Linux Server release 6.2 (Santiago"
- Build the latest version of RHEV/RHEL 6.x vdsm srpm here: http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/RHEV/SRPMS/
- Add the resulting rpms to a yum repo or create one using createrepo and serve it up where your SL node can get to it
- Register that repo with yum EG: add a repo file in /etc/yum.repos.d pointing to it
- Finally you will have to edit a value in the postgres database to actually get ovirt to execute vms on the SL (EL6) node once it is added
- since ovirt is built around FC16 it will pass "emulatedmachine" or the "-M" value to KVM as "pc-0.14" whereas on EL6 the value passed is "rhel6.2.0"
- thus to change it to what we desire run the following: psql -U postgres -d engine -c "update vdc_options set option_value='rhel6.2.0'
where option_name='EmulatedMachine' and version='3.0';"
-  after that make sure to restart the jboss service as the previous values are cached

We have plenty of native Russian speakers on this list ;-)

The short answer is that is that no one wrote a patch to Vdsm to let it
recognize Scientific Linux. You are more than welcome to write such a
patch.

I suspect that you would need a (yet unpublished) SL6.2 in order to have
oVirt work properly. Vdsm requires several packages by version for a
reason.
