BTW, I tried to install by booting directly from the DVD in a new Parallels Desktop 6 OS X Server VM, and it worked out of the box (i.e., it accepted to install also when booted form the machine-specific DVD): which is a good thing, as in Parallels you can't apply the "OSInstall" workaround, as there is no preformatted HFS+ virtual disk to mount.

As for the hint, it looks like the code, for some strange reason, is missing the backslashes (or the quotes, alternatively); so, it should be, respectively, in the Terminal:

/Library/Application\ Support/VMware\ Fusion/vmware-rawdiskCreator create /dev/disk1 fullDevice /Users/Shared/Virtual\ Machines.localized/Mac\ OS\ X\ Server.vmwarevm/Mac\ OS\ X\ Server lsilogic

/Volumes/Mac\ OS\ X\ Server\ Install\ Disc/System/Installation/Packages/OSInstall.mpkg

open /Volumes/Mac\ OS\ X\ Server\ Install\ Disc/System/Installation/Packages/OSInstall.mpkg

... if you copy and paste the text. And the "see also the previous thread" sentence of course shouldn't have been there (sorry for the mistake): it was a reference to a thread from a post of mine - from which I created the hint - on the VMware forums.

Talking about disk images, I have never been able to boot an OS X Server VM from a disk image: it always gave a stop sign (the one with the diagonal bar), after some time; maybe because I made the image in the CD/DVD master format? But probably that's not the problem...
