When i said in my message "real 8Gb Memory Ram", it means that I have 2 slots each one which contain 4Gb Memory Ram. "real 12Gb Memory Ram", it means that I have 3 slots each one which contain 4Gb Memory Ram.
And yes, i created Hugepages for the VM with the Debian Wiki ( https://wiki.debian.org/Hugepages). For 2048Mb allocate to the VM, i set "vm.nr_hugepages" to 4096. But i can't set 8192 to "vm.nr_hugepages" and set 4096MB for the Guest, I have not enough memory for the Host (I can use the host but if i launch Virt-Manager + VM, 99% of Memory Ram is used so the host freeze) 2016-06-21 19:37 GMT+02:00 Brett Peckinpaugh <b...@erylflynn.com>: > Are you using huge pages? > > On June 21, 2016 10:31:22 AM PDT, Berillions <berilli...@gmail.com> wrote: >> >> Hi guys, >> >> I found where come from the issue.
