Description of problem: ovirt-guest-agent should load acpiphp module on service start due to hotplug / unplug PCI device like block device -> /dev/vdX Version-Release number of selected component (if applicable): [root@client01 ~# rpm -qa | egrep 'rhev|ovirt' rhevm-guest-agent-1.0.7-10.el5ev [root@client01 ~# rpm -qa | grep release-5 redhat-release-5Server-5.10.0.4 How reproducible: Always Steps to Reproduce: 1. Install rhel5 VM 2. add rhel-i386-rhev-agent-5-server channel (for 32bit rhel5 3. yum install rhevm-guest-agent -y 4. service ovirt-guest-agent restart 5. lsmod | grep acpiphp --> none output Actual results: ovirt-guest-agent won't load acpiphp module Expected results: ovirt-guest-agent should load acpiphp module if it's hasn't yet loaded

what PCI block device hotplug A host passthrough using a vdsm hook for this? Or regular "hotplug disk" via UI? is this RHEV or oVirt?

First of all you have to install the oVirt guest agent and the RHEVM guest agent anyway. When you install them you can also install the acpiphp module and configure the OS to make it load the module on startup. Having such a specific workaround for RHEL5 is in my opinion not any helpful. It is a nice thing to know that we could support disk hotplugging but if you are using an older OS and you want to use such a feature then the OS must be configured to support it anyway. From my PoV this feature is not really worth it for such a specialized task where this is actually the administrators thing to decide.
