Hi,
I have a KVM box which has 4GB physical memory totally, I'd like to
know how much I can use to run my domains, and how much will be
reserved by hypervisor(KVM) itself?
Thanks!
KVM and the Linux host use relatively low amount of memory.
Unlike other hypervisors you know, kvm does not reserve memory and also
is able to swap the guest memory, so you can even use more than 4G for
your guest. (Just note swapping will be slow)
