Managing Memory Resources for Virtual
Machines
Managing Resources
This section describes the process of managing memory resources for virtual machines.
Configuring Main Memory Resources
The main memory resources for virtual machines include the following:
• main memory
• video memory
The process of managing these resources is described below.
Configuring Main Memory
To configure the amount of memory that will be available to the virtual machine, use the -memsize
option of the pctl set command. The following session shows how to change the
amount of memory for the MyVM virtual machine from 512 MB to 756 MB and to check that the
new value has been successfully set:
# pctl list -i MyVM | grep memory
memory 512Mb
# pctl set MyVM --memsize 756
Set the memsize parameter to 756Mb
The VM has been successfully configured.
# pctl list -i MyVM | grep memory
memory 756Mb
You can configure the memory size for both running and stopped virtual machines.
Configuring Video Memory
To set the amount of video memory to be available to the virtual machine's video card, use the -videosize
option of the pctl set command. Assuming that the current video memory size of
the MyVM virtual machine is set to 32 MB, you can increase it to 64 MB by running the following
command:
# pctl set MyVM --videosize 64
Set the --videosize parameter to 64Mb.
The VM has been successfully configured.
To check that the new value has been successfully set, use this command:
# pctl list -i MyVM | grep video
video 64Mb
