Hello Team,
I have generated Azure image using packer but facing some challenges with packer generated image during boot time.
In builder section, I have added an additional disk of size 40GB and after partitioning this disk, we are performing some file operation during the installation process. This process is taking longer than usual. Without packer it takes 20 mins to complete all the installation process, whereas with packer it is taking around 50 mins. I have pasted the template below for your reference. kindly let me know your comments/thought on this.
Looks like it is selecting SCSI driver by default for packer vm. I am suspecting this might be the cause. So is there any options available to use different driver in builder section.
Packer version : 1.6.5
