At Bobcares, we often get requests from our customers regarding Hyper-V errors as a part of our Server Management Services.

Why does Hyper V error 18590 occur?

A shutdown is triggered in the system without notifying the service in the server. During a clean shutdown, it works as by sending a signal to the service to turn off then Shutdown the machine.

If this process does not happen, the event is logged with the Event ID 18590.

How we fix Hyper V error 18590

Recently one of our customers contacted us with this error. Now let’s discuss how our Support Engineers help our customers resolve it.

Power issue

One of the common reasons for the event ID in the log is because of the issue with the power supply.

When the power supply is down thus making the Virtual Machine Shutdown unexpectedly.

If the issue with the UPS attached to the Hyper-V servers, then we suggest our customers contact the UPS Manufacture. Also, we suggest them to make sure to use the UPS manufacture software correctly to handle the battery threshold level.

Firmware update for Hyper V error

Recently one of our customers contacted us saying that the server unexpectedly keeps shutting down and no power interruption is happening.

On further analyzing the issue, we found that Hyper-V servers are facing issues with a CPU microcode update. Thus to resolve the error we update the firmware to the latest one. Let’s discuss how our Support Engineers update the firmware for our customers.

1. Initially, we log in to the management interface. Then we go to Maintenance and select Firmware update.

2. Now we enable update mode by clicking the Enter Update Mode.

3. Then we upload the ZIP file. Now the screen will show the current and the newly added firmware. We confirm the version and click on Start Upgrade.

4. Once the update is complete the management interface will reboot. It will return back to the login screen.

After the firmware update, we monitored the servers. The Virtual Machine was stable after the update.

If the issue still persists we need to upgrade the Intel processors on the Hyper-V host server to resolve it.

Power control

Another solution to the error is to make changes to the power management settings in BIOS.

To make the changes in the settings we enter the BIOS. Then we select Power Management in BIOS.

We change all the systems from Active Power Controller to Maximum Performance.

Thus the CPU ready times drop to a normal level. This way we resolve the error.
