Doc Text:	Red Hat Enterprise Linux 6.3 included the new qemu-kvm-rhev package. Existing versions of VDSM were not able to correctly determine the version information for hosts with qemu-kvm-rhev installed. As a result the KVM version would be listed as 'N/A' for these hosts in the Red Hat Enterprise Virtualization Manager. VDSM has been updated and will now correctly report the KVM version for hosts, regardless of which qemu-kvm package is installed.	Story Points:	---

Description Guohua Ouyang 2012-05-25 09:37:34 UTC

Description of problem:
KVM version is N/A after rhevh show up in rhevm.
if upgrade from rhevh-6.2-20111117.0 build to rhevh-6.3-20120523.1 build,
the kvm version displayed wrong version 0.12.1.2 - 2.209.el6

# rpm -qa | grep kvm
qemu-kvm-rhev-0.12.1.2-2.295.el6.x86_64

# rpm -qa | grep vdsm
vdsm-4.9-113.1.el6.x86_64

with rhevh-6.2-20111117.0 build, the kvm version is 0.12.1.2 - 2.209.el6 , so it's a regression issue of vdsm.

Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.3-20120523.1.el6
vdsm-4.9-113.1.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. register rhevh to rhevm

Actual results:
KVM version is N/A in RHEVM 

Expected results:
KVM version is 0.12.1.2-2.295.el6

Comment 2 Mike Burns 2012-05-25 11:19:31 UTC

This is due to the move to qemu-kvm-rhev in 6.3.  

in vdsm/caps.py


    KEY_PACKAGES = ['qemu-kvm', 'qemu-img',
                    'vdsm', 'spice-server', 'libvirt']

    pkgs = {'kernel': kernelDict()}
    try:
        for pkg in KEY_PACKAGES:
            rc, out, err = utils.execCmd([constants.EXT_RPM, '-q', '--qf',
                  '%{NAME}\t%{VERSION}\t%{RELEASE}\t%{BUILDTIME}\n', pkg],
                  sudo=False)
            if rc: continue
            line = out[-1]
            n, v, r, t = line.split()
            pkgs[pkg] = dict(version=v, release=r, buildtime=t)
    except:
        logging.error('', exc_info=True)

    return pkgs


This could be solved using "--whatprovides" flag to rpm command

            rc, out, err = utils.execCmd([constants.EXT_RPM, '-q', '--qf',
                  '%{NAME}\t%{VERSION}\t%{RELEASE}\t%{BUILDTIME}\n',
                  '--whatprovides', pkg], sudo=False)

Comment 9 Dan Kenigsberg 2012-06-23 15:15:09 UTC

now that the patch has been pushed to the rhev-3.1 branch (v4.9.6-14-6-g3a0496e), this bug has exhausted its purpose.
