Original GitHub issue: https://github.com/retspen/webvirtmgr/issues/157

I just begun using webvirtmgr (amazing application) and noticed that the views and edit pages for virtual machines do not show the Used and Max memory or vcpus separately. My workflow is to typically set the max memory and vcpu to double the allocated value.

Before I worked on a PR I wanted to check if current memory and vcpu representations on the web interface were intentional.

Example of a domain XML that has memory of 2GB max and 1GB allocated and 2 VCPUs max and 1 allocated.

<domain type='kvm'>
  <memory unit='KiB'>2097152</memory>
  <currentMemory unit='KiB'>1048576</currentMemory>
  <vcpu placement='static' current='1'>2</vcpu>
</domain>

Ideally the interface would show these 2 values separately for both memory and vcpu so the current allocation and max allocation could be viewed and set.

From what i see in the code the amounts allocated are fixed, this is why there is no max value for neither cpu or memory so it is allocating from start what you give it.

It would be probably good to add max values for each but at the same time this might be better handled in a autoscaling feature ??
