PACI: Cannot open VNC console for VM from PACI CP

Article ID: 120075, created on Feb 11, 2014, last review on May 10, 2014

APPLIES TO:
  • Operations Automation 5.5
  • Virtuozzo
  • Virtuozzo hypervisor

Symptoms

  1. Customers cannot open VNC Console for virtual machines from PACI CP.
  2. Update 4 for POA 5.5 is not installed.
  3. Parallels Server hosts many other VMs (>15).

Cause

Due to the number of VMs and running VNC services for those VMs, the task to (re)start VNC service for VM on opening Console from PACI CP might take more than 1 minute. PACI CP currently has the timeout for this operation of 1 minute, thus the error is displayed.

Resolution

  1. Update POA installation to 5.5.4.

    This does not fix the issue completely, however VNC console is not restarted if it is accessed from the same session. That is why accessing VNC console again in 1-2 minute should load VNC applet.

  2. Decrease the number of running VMs to 12-15 to decrease VNC service start time.

    It is understandable that this can lead to underutilization of the hardware. In this matter, there are the following requests submitted:

    CCU-7704 to increase the timeout in PACI CP and make this timeout configurable. PSBM-24928 to decrease the time needed to start a VNC console on a busy server.
