I am trying to improve my understanding of the boot up process for a windows machine running on top of xen and what happens behind the scenes at hypervisor level before guest machine starts.

I tried searching the available documentation but could not manage to find anything.

Can you please share some pointers?

Apologize in advance if this question is not relevant to this forum.

Hi Shiva,

TBH you'd be better posting to xen-devel for this question... There's nothing particularly special about Windows; it's essentially 'just another OS' running in an HVM container. The construction of that container does not differ according to the OS that will run inside it. The only real difference with Windows is what happens post-boot, since Xen provides a certain number of 'viridian' (a.k.a. Hyper-V) enlightenments, which are not generally used by other OS when running in a Xen environment.
