Was trying to install Solaris 10 from sol-10-u11-ga-x86-dvd.iso today and it wouldn’t boot on a Generic/Generic/1GB RAM/8GB disk x86_64 KVM VM,. It failed with a kernel panic.
It seems related to the amount of RAM because I bumped it up to 2GB and the VM booted and I’ve started the installation.
As a note to self, 8GB is not enough for a Developer install either. I went with 14GB.
