Im running Windows 7 on a Acer Aspire 5538 with an AMD Athlon(tm) X2 L310. I checked the specs, I also used an app that starts with an "s" to determine if my machine had AMD-V or virtualization capability and it does.
Although my laptop is/was the best model at the time it's missing the Advanced options in startup bios so I can't see if it's enabled or or not. I have BackTrack running in virtualbox, but I get "hardware not supported" when I try launching Mountain Lion from VMWare. VirtualBox starts the hackboot1 loader but after selecting the img and try booting it the screen goes blank.
I've attempted by converting my installesd.dmg into a iso, vmdk and rar file (to install from sd card) with no luck.
