Thread-topic: Need help with xen boot time

[AMD Official Use Only - General]

Hi All,

I am Raveendra .Currently I am working on xen hypervisor with Ubuntu 22.04 .Compared to Native ubuntu kernel ,dom0 with xen is taking around 1.8s more to boot.

I used system-analyze tool for calculating boot time.

Can any body publish the boot time of xen that you are observing, also is there anyway to optimize the xen boot time,related to xen build or any command line options.

Thanks,

Raveendra
