[Xen-devel] Question: PV ops Fedora 16 Initialises Hypercall Page Twice?

[John McDermott CIV <john.mcdermott@xxxxxxxxxxxx>]

Xen Developers,

I noticed that my PV ops guests cause the hypervisor to invoke 
hypercall_page_initialise twice from traps.c (i.e. through 
wrmsr_hypervisor_regs), for different hypercall_page addresses. Looking at the 
code, I see hvmloader.c causing one of those, in its main. I read the HVM 
Loader Xen wiki page, Googled, spelunked the source, etc. but cannot find where 
/ why the other hypercall page is being requested. Is the other hypercall page 
being initialized by qemu-dm and the hvmloader page is discarded?

Sincerely,

John McDermott
