I was wandering how does Windows XP virtual machine function on TRIM aware OS (saz WIndows 7 x64) with SSD?

Is the SSD drive compromised in any way, or does the TRIM functions on the underlying OS as it should?

TRIM will run normally on the host.

Guest OS are unaware of their surroundings and Windows XP will not know its using a virtual disk or its installed virtually.

Windows XP has no TRIM support. You have to sdelete (zero free space) and vmkfstools -y (it uses full size shortly to get through with this task.
Windows vista+ or linux 2.6.31+ has TRIM support and can work together with VAAI DISCARD support or with thin disks.
