Description Roman Hodain 2014-07-21 06:21:21 UTC

+++ This bug was initially created as a clone of Bug #1102072 +++

Description of problem:
RHEVM 3.4 admin UI doesn't show in tab VMs "Application" succesfully installed applications on that VM.
RHEVM - 3.4.0-0.20.el6ev

Host configuration:
Kernel Version: 2.6.32 - 431.5.1.el6.x86_64
KVM Version: 0.12.1.2 - 2.415.el6_5.6
LIBVIRT Version: libvirt-0.10.2-29.el6_5.5
VDSM Version: vdsm-4.14.2-0.4.el6ev

How reproducible:
100% reproducible

Steps to Reproduce:
1. Create VM (1024M, 4 CPU)
2. Connect to VM using SPICE
3. Install RHEL 6.5 from PXE
4. Update kernel 
# yum update kernel
Check version:
# rpm -q kernel
kernel-2.6.32-431.el6.x86_64
kernel-2.6.32-431.17.1.el6.x86_64
5. Update repo files
5.1. rhel65.repo   
[rhel-65]
name=RHEL_65
baseurl=<SNIP>
enabled=1
gpgcheck=0
 
[rhel-65-optional]
name=RHEL_65_OPTIONAL
baseurl=<SNIP>
enabled=1
gpgcheck=0
 
[rhel-65-zstream]
name=RHEL_65_Z
baseurl=<SNIP>
enabled=1
gpgcheck=0
rhel65.repo (END)

5.2. rhevm.repo
[qa-latest]
name=QA Latest build
baseurl=<SNIP>
enabled=1
gpgcheck=0
rhevm.repo (END)

[rhev-65-channel]
name=RHEV_65
baseurl=<SNIP>
enabled=1
gpgcheck=0

6. Install guest agent application
# yum install rhevm-guest-agent-common
Check version:
# rpm -q rhevm-guest-agent-common
rhevm-guest-agent-common-1.0.9-1.e16ev.noarch

7. Start guest agent 
# service ovirt-guest-agent start

8. Go to RHEVM admin portal
Select VM's tab "Application"

Actual results:
Nothing

Expected results:
kernel-2.6.32-431.el6.x86_64
kernel-2.6.32-431.17.1.el6.x86_64
rhevm-guest-agent-common-1.0.9-1.e16ev.noarch
