Yes, some users have reported issues with booting CentOS/Alma 9 on Virtual Machine Manager. There could be several reasons why this is happening, including compatibility issues, incorrect configurations, or software/hardware limitations.
To troubleshoot this issue, you can try the following steps:
Check if your Virtual Machine Manager is up to date and supports CentOS/Alma 9.
Make sure that the virtual machine settings are configured correctly, including the CPU, RAM, and disk space.
Verify that the CentOS/Alma 9 ISO file you are using to install the operating system is not corrupted or incomplete.
Try booting the virtual machine in safe mode or with different boot options to see if that resolves the issue.
If none of the above steps work, you may need to consult with your hosting provider or seek help from a Linux administrator.
