I've noticed that the "recommeneded" and "minimum" requirements differ depending on whether the live media is booted from DVD or USB.
From DVD: Recommended = 8G, Minimum = 6G
From USB: Recommended = 7G, Minimum = 5G
Don't know whether there's a real reason for the difference, or if it's just a typo.
While I appreciate your practicality,that approach would exclude the use of S11 as a series of VMs on some other OS.
In addition, this type of error makes it difficult to trust the documentation. It's as if they didn't care when they tested the different scenarios that they're trying to market.
We are talking about harddisk space, not RAM (is that what you were thinking?). What I think the other Alan is saying is that the diskspace used after installation can vary, based on how many boot environments (BE) you want to keep and how much software you want to install after the basic installation is complete. It does not make the VM any less portable, which might be the case if we were referring to RAM.
Meanwhile, I am working on finding out whether it is a typo or if there really is a difference, though installation from the 2 types of media should result in the same filesystem.

Since Solaris 11 is generally a pretty quick install you could just do a default install on both and then use df -h or du -sh / to figure out how much space it's taking up. Maybe one image holds more than the other. Personally I don't know.

I can see where it would be an issue if you're hosting thousands of VM's something like an EMC device. Or something smaller but along those veins.
I just use them as a guestimate at best since you'll probably need more than just the base OS anyways.

removed link to solaris 10 vm download
I am referring to HD space, and appreciate that someone is paying attention to at least one of my questions.
Here's the link I was looking for.
Solaris 11 VM images.
We looked at the installation for both the DVD and USB images, and we saw both show Recommended = 7G, Minimum = 5G. Can you confirm that you were looking at the install from the LiveDVD image from Solaris 11 11/11?

I've saved a screenshot of such, see upper right corner
Confirmed a second time, ref

Thanks, that helps. I haven't been able to reproduce it. Before I report the issue you are seeing, can you confirm the exact file you are using for creating your USB image?
FYI, I've been testing the live DVD on a VM in a KVM-based QEMU system. I just tried the same iso on VirtualBox, and got the 7GB/5GB numbers. So that suggests variation based on VM solution.
The difference is based on the amount of physical memory detected on the system (or VM in this case) If there is less than 900mb, an extra 1GB is allocated to swap space. Try allocating more RAM to the QEMU guest.
I'm not trying to be difficult... but on the two KVM VMs that I'm using for testing, the allocated RAM is already 1536 and 2048 MB.
How much RAM is necessary to bring the recommended space down to the standard 7G/5G?
That's puzzling. If you have 1GB or more you should be fine. If you are running the LiveCD environment, try also running the "Device Driver Utility" from the desktop icon and see how much memory it reports.
In order to debug this problem, please run the installer in debug mode from the system that you believe is reporting the wrong recommended size.
To run the installer in debug mode:
You can just quit the installer after the disk selection screen with the suggested size comes up.
The install log is at /system/volatile/install_log. Please put that file somewhere and point us to it.
