→‎All zdtm tests: Add more detailed description for --lazy-pages, --lazy-migrate and --remote-lazy-pages.

;--lazy-pages
 
;--lazy-pages
: Restore pages on demand.
+
: Restore pages on demand. In this case dump works "normally", restore skips the memory pages that can be handled on demand and lazy-pages daemon handles the page faults and reads the memory contents from the image files.
    
;--lazy-migrate
 
;--lazy-migrate
: Allows testing of lazy migration when running ns or uns flavor.
+
: Allows testing of post-copy migration when running <code>ns</code> or <code>uns</code> flavor. It cannot run with the host flavor because during post-copy migration the migrated tasks should exist both on the source and the destination.
    
;--remote-lazy-pages
 
;--remote-lazy-pages
: Simulate lazy migration with page server that can send pages.
+
: Simulates post-copy memory migration. Here again, the dump works "normally", but the lazy-pages daemon does not read data from the image files but requests it "over the network" for the page-server. It is the page-server that reads memory pages from the images and simulates what 'dump --lazy-pages' wound have done.
