Hey folks -- suppose ESX has decided to swap out certain pages of a guest VM to swap space on the host because there was severe memory crunch -- how do we make sure ESX recalims all pages back from swap space to the RAM whenever the RAM is available again ?
we have seen cases where a guest VM continues to use the swap space - even when the memory becomes available again -- consider this case: a host has been put in maintenance - there is crunch for memory on other hosts - so some guests swap out -- now the host is back in farm - some VMs fly out to the host but still the VMs which were using swap memory continue to do so ... how do we tell ESX to copy things from swap to memory again
this needs to be done immediately when memory becomes available
as always great group -- thanks in advance
