I have VMWare ESXi 4.0 installed (not embedded) on a server. datastore1 holds 2 wirtual machines on it currently, and reports about 9.5 GB free out of 131GB total disk space.
I wish to virtualise an XP machine that runs our telephone software. Currently this has a disk of about 9.5 GB.
Can I safely use all the space on datastore1 or should I leave some free space available?
