How to test PageFusion ?

I'm running 7 WinXP VMs, with 2 GB RAM each. How to know how much RAM is "fused" ?

According to docs,
I did:

C:\Program Files\Oracle\VirtualBox>VBoxManage metrics query "Windows XP PageFusion VM1" RAM/VMM/Shared,Guest/RAM/Usage/Shared
Object Metric Values
---------- -------------------- --------------------------------------------
Windows XP PageFusion VM1 Guest/RAM/Usage/Shared

C:\Program Files\Oracle\VirtualBox>

...
but no values returned.

You are running seven VMs and nothing is fused???

Alex,
Did you enable page fusion on each guest? It is not enabled by default.

[Technologov]

Yes I did enable host-side. Not sure if I need to enable guest-side (inside of each guest)

[Perryg]

It is the guest that needs to be enabled.

Code: Select all

VBoxManage modifyvm <vm name> --pagefusion on

[Technologov]

But this command is host-side. (there is no VboxManage inside guest)

[Perryg]

Yes the command is run from the host but it enables page fusion in each guest thus the <vm name> . If you enabled it in the guest and then clone it you should already have it enabled but you still need to check.


Run VBoxManage showvminfo < vm name > to verify if it is enabled or not.

[Technologov]

Yes, I did run this command for all of my VMs.
