15.2.2. Collecting data about virtual machines
Collecting data about malfunctioning virtual machines (VMs) minimizes the time required to analyze and determine the root cause.
Prerequisites
- For Linux VMs, you have installed the latest QEMU guest agent.
For Windows VMs, you have:
- Recorded the Windows patch update details.
- Installed the latest VirtIO drivers.
- Installed the latest QEMU guest agent.
- If Remote Desktop Protocol (RDP) is enabled, you have connected by using the desktop viewer to determine whether there is a problem with the connection software.
Procedure
-
Collect must-gather data for the VMs using the
/usr/bin/gatherscript. - Collect screenshots of VMs that have crashed before you restart them.
- Collect memory dumps from VMs before remediation attempts.
- Record factors that the malfunctioning VMs have in common. For example, the VMs have the same host or network.
