I've just tried PS and first impressions are not good. I have two VMs, both Solaris 10. The first Solaris 10 doesn't get past the GRUB boot loader and crashes. The second (Solaris 10 U4, the other is U3) starts, but stays at the Kernel loading screen with CPU @ 100%. Both these images came from PD.
I've tried creating a new VM using PS, this one boots but the performance is dire. It took 20 mins just to load the kernel, it takes seconds on PD.
This is on a Mac Pro, 2 x 3GHz CPUs with 13Gig RAM, I am not short of resources.
Is Solaris not really supported?
