Advanced Virtual Machine Attributes
You can use the advanced virtual machine attributes to customize virtual machine configuration.
Table B-4. Advanced Virtual Machine Attributes
Attribute Description
sched.mem.maxmemctl Maximum amount of memory reclaimed from the selected virtual machine by
ballooning, in megabytes (MB). If the ESX/ESXi host needs to reclaim additional
memory, it is forced to swap. Swapping is less desirable than ballooning.
sched.mem.pshare.enable Enables memory sharing for a selected virtual machine.
This boolean value defaults to True. If you set it to False for a virtual machine, this
turns off memory sharing.
sched.swap.persist Specifies whether the virtual machine’s swap files should persist or be deleted when
the virtual machine is powered off. By default, the system creates the swap file for a
virtual machine when the virtual machine is powered on, and deletes the swap file
when the virtual machine is powered off.
sched.swap.dir VMFS directory location of the virtual machine's swap file. Defaults to the virtual
machine's working directory, that is, the VMFS directory that contains its
configuration file. This directory must remain on a host that is accessible to the virtual
machine. If you move the virtual machine (or any clones created from it), you might
need to reset this attribute.
