I am experiencing a rather odd problem. If I try to boot from a Linux install CD in the guest, it will not boot--just locks up. Booting the guest from an XP or Vista install disk works just fine. I've tried booting Xandros, Knoppix, Mandriva, Sabayon (Gentoo), but none work. It shows the initial unpacking linux, and then stops responding.
My host system is Sabayon 3.3 x86, on AMD 64 X2 3600+, 2 gig memory.
