[edk2-devel] guest boot with edk2 on Xen hypervisor takes more time

[A Sudheer]

Hi All,

I tried the same with edk2 tianocore code base and see behavior is same. Time taken to boot guest is same.

i enabled edk2 ovmf logs and could see memory conversion in MdeModulePkg/Core/Dxe/Mem/Page.c , CoreConvertPagesEx() takes long time.
Can someone tell me if this conversion can be avoided.  Behavior is same with Ubuntu & android guests.

Attached the complete log file xl-edk2-ovmf-android-log2.txt .
