14.13.8. Changing the Memory Allocation for the Domain
virsh setmaxmem domain sizeallows the setting of the maximum memory allocation for a guest virtual machine as shown:
virsh setmaxmem rhel6 1024
The size that can be given for the maximum memory is a scaled integer that by default is expressed in kibibytes, unless a supported suffix is provided. The following options can be used with this command:
--config- takes affect next boot
--live- controls the memory of the running domain, providing the hypervisor supports this action as not all hypervisors allow live changes of the maximum memory limit.
--current- controls the memory on the current domain
