Re: [Qemu-devel] qemu dynamic translation (system design) question

[S . P . T . Krishnan]

Hi Laurent,

Thanks for the direction.

I am just thinking.  If I run a guest OS once and observe the blocks
that are translated and may be reused.  Then I again re-run the OS,
can I expect the same blocks are translated ?  i.e., is qemu
consistent on how it partitions the asm into blocks on successive runs
or the guest OS ?

Note: in both cases the user doesn't interact with the Guest OS.  It
is up for, say 1 min and then shutdown in both runs.

regards,
Krishnan
