Ok, so i will grab a 4 RAM GB, install a hypervisor on it (it will take almost 1 GB)
What hypervisor is grabbing so much RAM?
-
@coliver no dear, i already tried XenSever, it consume about 700 MB,
-
@IT-ADMIN said:
... and the rest is devided btw the 2 VM, one apache 1.5 GB RAM and one for Mysql 1.5 GB RAM, is it fine now ???
That's plenty, yes. Far more than we use for that stuff.

Are you sure about that? How did you determine that it was using so much? I've never seen it grab that much.
-
what makes apache not playing well with mysql if they are on the same server ??
-
-
it takes 1 GB
-
I don't know much about XenServer, but I know you can limit the amount of memory assigned to the Hypervisor (physical host) itself... Not sure where to do that though.

-
Ya mine's using close to 2GB
-
anyway it is another discussion about hypervisors we made it 6 months ago,
why it is recomended to make apache and mysql in seperate servers ??

because they compete heavily for physical resources and they scale at different rates

ah ok, i see what you mean,
thanks -

Default is 752 MiB.

They play fine, it's you we are trying to alter.

Use the free-m command, not a graphical representation. That's not the number that you think that it is.

That's the RAM for each VM and the host. 8% is allocated for the dom0. It's not actually using that much, but that much is allocated by default, bad wording.

No, that's not an issue. Specifically the issue is the potential to write code that relies on locality.
