[ovirt-devel] Can't join vdsm(4.17.0-390.gita3163f3.el7.x86_64) to Cluster 3.6

Tue Feb 10 15:39:31 UTC 2015

Hello Yaniv and all!

So i did this:
I tried to install clean rhel7.1 host with the right libvirt version(libvirt-1.2.8-16.el7.x86_64,vdsm-4.17.0-394.gitb237397.el7.x86_64) and failed to join this host under 3.6 cluster.
Host red-vds2.qa.lab.tlv.redhat.com is compatible with versions (3.0,3.1,3.2,3.3,3.4,3.5) and cannot join Cluster mb3.6 which is set to version 3.6.
After failing i checked the /usr/share/vdsm/dsaversion.py and saw that:
version_info = {
    'version_name': version_name,
    'software_version': software_version,
    'software_revision': software_revision,
    'supportedENGINEs': ['3.0', '3.1', '3.2', '3.3', '3.4', '3.5'],
    'supportedProtocols': ['2.2', '2.3'],
    'clusterLevels': ['3.0', '3.1', '3.2', '3.3', '3.4', '3.5'],

So i added the 3.6 for cluster levels and engine support lines, restarted vdsm and finally managed to join my rhel7.1 host to 3.6 Cluster.

All of this means that rhel7.1 hosts with vdsm 4.17.0 and libvirt version -libvirt-1.2.8-16.el7.x86_64 are still not supported by default for 3.6 clusters and dsaversion.py file must be edited manually in order to join to cluster 3.6.
I guess this must be changed.

Best regards,
Michael B

Thank you all!

Ok, so how can i get this right libvirt version for rhel7? not7.1 and without any dependencies issues??
I want to join rhel7 host, with the right libvirt version to 3.6 cluster..is it possible?

because we don't need it- i explained there
the cluster check is only after the supportedVDSMVersion does not catch. 
we failed to add the host to the cluster because the libvirt version . 
as it is now, with the right versions, you should be able to add vdsm 
4.17 to lastest engine regardless the cluster level
