Virsh Autostart – Let’s discuss it in detail!!
Are you confused with Virsh Autostart? We will help you with it.
Usually, virsh commands are very useful at the same time a bit confusing.
At Bobcares, we often receive requests to fix some virsh errors as part of our Server Management Services.
Today, let’s discuss how our Support Engineers use these commands efficiently for our customers.
More about Virsh
Before discussing the topic in-depth, let’s have a look at virsh.
Virsh is the interface for managing virsh domains. And, Virsh commands can create, pause, restart and shutdown domains.
Also, it can list the domains available in the Virtualization platform.
To run virsh commands, we need root privileges. Otherwise, it will end up throwing errors.
So, let’s discuss how can we autostart domains using the virsh command.
How we use Virsh Autostart?
Having a decade of experience in managing servers, our Dedicated Engineers frequently get requests to solve virsh command errors.
Recently, one of our customers approached us with an error related to virsh.
He had a dedicated server and it had been crashed one day.
To fix it, he booted the server. But, he found that some of his virtual machines didn’t boot.
Our Support Engineers checked the error in detail. To get the basic information about the domain, we used the below command,
virsh dominfo Domainname
When we executed the above command, we got the following result.
On checking, we found that error occurred because autostart wasn’t enabled.
Usually, we can configure a domain to automatically start at boot.
Auto-restart helps to start the virtual machines at the boot time without executing the virsh start command.
So, to turn the autostart on, we used the command,
virsh autostart domainname
Finally, after turning the autostart on, the VM worked fine in the next reboot.

In short, we use virsh autostart to automatically start the Virtual Machine at the boot time. In today’s write up, we discussed virsh and also saw how our Support Engineers help our customers to fix the errors related to it.
