For 64-bit (x86_64) hardware nodes, follow these steps:

  1. Download full PVA Agent distribution:
    wget http://download.pa.parallels.com/pva/4.6.3/downloads/linux/x86_64/pva_agent-linux-x86_64-4.6-1722.tar.gz
  2. Uncompress the archive:
    mkdir /tmp/pva_install
    tar -xvzf pva_agent-linux-x86_64-4.6-1722.tar.gz -C /tmp/pva_install
    cd /tmp/pva_install/pva_agent
  3. Uninstall current PVA Agent:
    NOTE: This step is required for the reinstallation procedure only.  Otherwise, you may skip this step.
    ./pva-setup --uninstall
  4. Launch PVA Agent installation:
    ./pva-setup -r local --install

Power Panel shows alerts for all containers when log in from POA CCP

Symptoms
When someone accesses Power Panel resource alerts via POA CCP (Hosting  >  Configuration & Administration  >  VPS > VPS Management > Login to VZPP via VPS IP address > Resource Alerts), it shows alerts for all containers hosted on the hardware node, instead of showing alerts for the particular VPS.

Resolution

  1. Open the dashboard.xml file with the text editor:

    Linux: /etc/opt/pva/pp/plugins/core/pp/dashboard.xml
    Comment out the logs.alerts section, so the resulting section will look as follows:
        <!-- commented out as workaround for PVA-30401
            <item id="logs.alerts" href="$baseurl/vt/pp/alerts-pp" title="Resource Alerts" icon="qos_alerts" tip="alerts_screen" cred="vzcp.log.list" security-obj-type="ve.vz.vt">
                <text>On this screen you can see the alerts related to the resources that are nearing their limits.</text>
            </item>

        -->
  2. Open the menu.xml file with text editor:

    Linux: /etc/opt/pva/pp/plugins/core/pp/menu.xml
    Comment out the logs.alerts section, so the resulting section will look as follows:
      <!-- commented out as workaround for PVA-30401
            <item id="logs.alerts"
                href="$baseurl/vt/pp/alerts-pp?branch=env-home,vzpp"
                icon="qos_alerts"
                tip="alerts_screen"
                cred="vzcp.log.list"
                security-obj-type="ve.vz.vt"
            >
                <title>Resource Alerts</title>
                <screen id="01.01.00.00.04"/>
            </item>

        -->
  3. Reconfigure Power Panel:
            Linux: /etc/init.d/pvapp reconfigure
  4. Restart Power Panel services:
            Linux: /etc/init.d/pvapp restart
  5. Set numtcpsock, tcpsndbuf, tcprcvbuf of CTID 1
    [root@vps30 ~]# vzctl set 1 --numtcpsock 800 --save
    [root@vps30 ~]# vzctl set 1 --tcpsndbuf 5242880:10485760 --save
    [root@vps30 ~]# vzctl set 1 --tcprcvbuf 5242880:10485760 --save
