[Xen-devel] are there any hidden domains inside Xen when it is running?

["Haifeng Fang" <fhf25@xxxxxxx>]

hi, all:

 

i have programmed a little tool which can dump some information of key data-struct inside xen.

with the tool, i obtained some data related to "frame_table" as follows:

 

page_offset, page_number, count_info, is_allocated, reference, inuse_domain_id, free_list_order

    502636KB,     125659,   80000002, allocated,          2,          1,          0

    516092KB,     129023,   80000002, allocated,          2,          0,          0

    516096KB,     129024,   80000001, allocated,          1,      32754,          0

    523248KB,     130812,   80000003, allocated,          3,      32753,          0

 

in my testing, i have brought up two domains, i.e. domain0(0), domainU(1). But from the list above, there are another two domains, who are they?

 

thanks in advance.
