Hello,
Recently read an article by Ron van der Heij on use of CMM to flush a guests
memory. Included script to drop page cache.
I have two questions:
1) We are not running a VMRSMVM is that required to correctly implement
this process?
2) Are other people implementing a
I was never much enamoured with the original cpuplugd - and my customer
response to testing it was less than enthusiastic. This, however, looks more
interesting.
Now to see if I can convince the customer to retest using it (R/H 6.4).
