Hi,
I searched on net , but could not find it.
Does anyone know what is the equivalent tool of "xm top" in KVM.
Actually I was comparing the management tools of XEN with KVM. and it seems XEN excels KVM in that.
e.g.

In XEN, I can start the HOST OS with fixed amount of RAM. (dom0) , whereas in KVM I do not see this option. This may pose a great difficulty in future when I have to install a new VM on KVM installed HOST. Because Linux kernel eats as much RAM as it can over the period of time and it may give me wrong picture when I have to check for the available RAM while trying to install new VM.
Where as in XEN , xm top will give me clear picture.

Hello,

Thanks.

But that post does not answer my query. To some extent it answer my query but it requires GUI to setup .

Here is another one with command line tool.

In command line you can find information about your VM:
virsh dominfo your_vm_name

and you can fix size of VM memory:
virsh setmem your_vm_name 64
or edit XML-config for VM
virsh edit your_vm_name
<memory>65536</memory>

virt-top is one the command you may use, plus you alway you can force linux kernel with amount of memory you want your linux kernel to start with, like mem=xG or M, T, and for management option look at virsh command lines man page, plus if you have libguestfs installed it add more power full features. i think xen kernel have some limitation with memory.
