Comment 1 Dor Laor 2009-07-20 10:16:20 EDT
Marcelo, note that the migration fixes are not needed. Just any other fixes.
Comment 5 Marcelo Tosatti 2009-07-20 12:42:48 EDT
There are no major fixes (other than the migration one), which would prevent preview of hugetlbfs backed guests.

Of course some basic testing by QA would be nice.
Comment 6 Dor Laor 2009-07-20 15:08:54 EDT
In that case, it's much more simple. Marcelo, can you please post the dirty page tracking and we'll call it a day.
Since the performance group did stress test it quite well.

run RHEL4u8 32/64,RHEL5u4 32/64,window2k3 32,window 2k8 32 
and run stress inside the linux guests,sp2004 inside window guests 
both guest and host are healthy during the testing

Please make sure migration of a guest with large pages backed memory works.
This was the latest fix.
