All, I'm trying to build a virtualization/xVM server with Solaris as the host-system (i.e. Dom0). I have a machine with 1 4GB compact-flash card for the OS and 24 disk-drives for the guest-domains (using ZFS). While this machine has lots of cores and memory installed, my hope is to use just 2-cores and 4GB of memory for the Dom0.
Using UFS, my Dom0 space requirements were around 2GB, but when I select ZFS in the installer (b93), it calculates an enormous space requirement - around 10GB! I think this is because I currently have 16GB mem installed (though I plan to add more later) and so its reserving 1/2 physical mem for dump/swap; that is 1/2*16 + 2 = 10, but it really should be 1/2*4+2 = 4, which would barely fit my CF... Do I have to physically uninstall my memory before trying to install on the CF so the space requirements will fit? Also, given that the space-requirements are so close, I'm inclined to want to make the installer think I only have 2GB mem installed, so 1/2*2+2 = 3, which leaves a buffer for the install to succeed. But then, after the install and resintalling the physical memory (if I have to take it out), I would set the "kernel$" line in GRUB's menu.lst file to contain "dom0_mem=4G" - thus allocating 4GB to the Dom0, which should be more than enough to keep it from ever swapping. Just the same, would I have an issue since the dump/swap space was allocated assuming just 2GB mem? Thanks, Kent
