[Devel] Query on host swapping of guest pages.

[Arn]

Hi,

I need to know the following for some experiments I'm doing as part of
a school project:

Does OpenVZ support host swapping of guest pages ? That is : if a host
experiences memory pressure, can it swap out some of a guest's (guest
vm) pages and use them ? I assume that if this is possible then when
the guest needs to use the memory again it will be swapped back in ?
Can someone confirm if OpenVz does this ?

Also, can the host change the memory allocation for a guest at runtime
(while the guest is running) ?

Thanks
Arn
