VHD root disks and VM start-up process at XenServer

[Vadim Kimlaychuk <Va...@Elion.ee>]

Hello friends,

            I would like to understand how CloudStack creates/runs VM on XenServer host?  What source files contain process of VM start-up?
            I want to repeat this process manually on dedicated host, but it seems XAPI does not work with VHD disk images.  I can’t start VM from existing VHD file manually. Converting it to XVA is not the case I suppose.

            I have tried to create empty VM from XenServer template and replace root disk by my VHD file, but VM fails to start-up. Who can shed the light on this process?

Thanks,

Vadim Kimlaychuk

Hi,

I recommend you take a look at CitrixResourceBase. This is the "server
resource" for XenServer and is where commands such as "start VM" are
dispatched to.

Talk to you later,
Mike
