Troubleshooting Steps for Resolving Qualys Scanner Startup Issues
When the Qualys Scanner Virtual machine fails to start, check the event logs to identify the issue. We recommend checking the Hyper-V-VMMS Admin log under Applications and Services in Microsoft Windows. In most instances, the logs indicate the specific reason for the error. In this particular case, the virtual machine fails to start due to the There are not enough resources to complete the operation error, which is displayed in the following screenshots.
- When Qualys Scanner VM is not started.
- Check Admin log in Event Viewer for Errors.
- Check the available memory and logical processors on the host.
As mentioned in the Useful Command section, the systeminfo command provides details related to utilized memory on the Host, Get-WmiObject Win32_Processor | Select LoadPercentage | Format-List gives info regarding the Host CPU cores load.
The number of CPUs to allocated RAM ratio should always be 1:2, for example, 4 CPUS and 8 GB RAM. The maximum recommended size for a scanner instance is 8 CPUs and 16 GB RAM.
We strongly recommend disabling the Checkpoints setting on Hyper-V for all Qualys Virtual Scanner Appliance and deleting all created checkpoints for these virtual machines.
Qualys strictly prohibits creating a new virtual scanner instance from a snapshot or clone.
You can get the list of available checkpoints for a specific virtual machine, and delete these checkpoints for Qualys Scanner Virtual Machine with the following commands.
| Command | Description | Example |
|---|---|---|
| Get-VMCheckpoint -VMName <virtual machine name> | Displays the list of available checkpoints for a specific VM. |  |
| Remove-VMCheckpoint -VMName <virtual machine name> | Deletes the checkpoints for Qualys Scanner VM |  |
Adjust Memory and Processor settings, if needed, for the Scanner VM and restart it. The Scanner will boot from its original disk, not from a previously saved checkpoint.
