Set Advanced Virtual Machine Attributes
You can set advanced attributes for a virtual machine.
Procedure
1 Find the virtual machine in the vSphere Web Client inventory.
a To find a virtual machine, select a data center, folder, cluster, resource pool, or host.
b Click the Related Objects tab and click Virtual Machines.
2 Right-click the virtual machine and select Edit Settings.
3 Click VM Options.
4 Expand Advanced.
5 Under Configuration Parameters, click the Edit Configuration button.
6 In the dialog box that appears, click Add Row to enter a new parameter and its value.
7 Click OK.
Advanced Virtual Machine Attributes
You can use the advanced virtual machine attributes to customize virtual machine configuration.
Table 15‑3. Advanced Virtual Machine Attributes
Attribute Description Default
sched.mem.maxmemct
l
Maximum amount of memory reclaimed from the
selected virtual machine by ballooning, in megabytes
(MB). If the ESXi host needs to reclaim additional
memory, it is forced to swap. Swapping is less
desirable than ballooning.
-1 (Unlimited)
sched.mem.pshare.ena
ble
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.
True
sched.mem.pshare.salt A salt value is a configurable VMX option for each
virtual machine. If this option is not present in the
virtual machine's VMX file, then the value of
vc.uuid vmx option is taken as the default value.
Since the vc.uuid is unique to each virtual machine,
by default transparent page sharing happens only
among the pages belonging to a particular virtual
machine (intra-VM). If a group of virtual machines
are considered trustworthy, it is possible to share
pages among them by setting a common salt value
for all of those virtual machines (inter-VM).
