Hi everybody, I tried Workstation on my Core Duo Mac Mini; apart from what I think are probably beta issues (no full screen possible etc), everything works great - I'm definitely buying licenses when the release is out. If it's priced at 49,95 as the versions for the other host systems, it's a steal .. But: after my trial I installed Boot Camp and did a native XP install; since the necessary firmware update, launching a VM brings up the message that VT-X is present but disabled. Is it possible for me to reactivate VT-X in Open Firmware somehow, or is this a matter which must be solved by a new Workstation release? Cheers, Jan

VT-X disabled by firmware update?

Hi everybody,

Is it possible for me to reactivate VT-X in Open Firmware somehow, or is this a matter which must be solved by a new Workstation release?

Cheers,

MacBook - VT supported and enabled. 3. Mac mini - VT supported but disabled. Is it intention of Apple to reduce Mac mini functionality or just firmware bug - I don't know... __________________ Best Regards, anshar

I'd say there is probably just a glitch in the combination of these three - at least I really, really hope so. Being able to use Minis in our corporate environment would so rock :)

On a different note: I haven't really worked with VMs before, and especially not on the Mac, so please forgive me if this is a stupid question, but: what is the best way to exchange files between VM and host - i.e., make office documents created in the VM available to OS X?

The VM environment grabs its own IP address on the LAN, so you can set up a Windows share on either/both OS X and/or Windows and share files that way.

You'll also be able to share a folder/volume from the Mac environment into the Parallels environment using the Parallels tools.

Dave,

For various reasons I just don't want to fork out the cash for a Core Duo iMac or Mac Book Pro (I'm really holding out for the desktop machines) but with all this bootcamp and even more sexy to me virtulazation (I'm not really a gamer so this is just up my ally) the mini was looking like a real option to bide-my-time. Like I said I'm not a hard core gamer by any stretch so I can pretty much forgive the built in graphics (not happy but I can deal) but when I read that VT was crippled / disabled and or in some way not available stopped me in my tracks.

I hated to think it was done 'just to be nasty' aka a pure and heartless marketing move without any cost savings associated with it but it was the first thing that jumped into my head. Sure save a few bucks not having an ATI chipset (gulp well okay) but no VT when it is working fine everywhere else... That I couldn't forgive Apple for.

Well anyway I'm glad to read what you posted and I and I'm sure many others are quite interested in hearing anything more you might find out.

Thanks for (pretty much) restoring my faith in Apple. :D

Dave

The reason I ask is I have not installed bootcamp yet, but I have installed 10.4.6, I have installed firmware update 1.0, and I have installed the parallels workstation trial and I do have VT-x support working. I was planning on doing bootcamp shortly but now I'm wondering.

How did you test if VT was enabled? I wrote a VT test program based on the Xen start-up routines and it indicates VT is not only present, but enabled.

furfurfur Junior Member Join: Apr 2006 Posts: 21	Hi guys Just wanted to mention that I bought a mini yesterday (1.66 Duo / 1GB) and all I've done is update to 10.4.6 and installed Parallels - I haven't installed any new firmware for Boot Camp or otherwise. I get the message from Parallels that VT is disabled in the BIOS. Cheers James

Not sure how to check the MD5 hash but the date and file size are right.

One of the Parallels programmers has written a simple kext to demonstrate that VT is disabled/inaccessible on the Mac mini in firmware, and is in communication with Apple on the issue.

Scott Willsey Senior Member Join: Apr 2006 Posts: 174	Dave, How do you explain when I run parallels that it shows VT-x enabled on my core duo mini, and that xp runs quite fast (faster than expected) under it? I'm wondering if the Parallels test wasn't against the original mini firmware and not the update that came out on the 4th. Either that or they haven't tried it on a core duo, only a core solo? I don't know, I'm guessing, but it's working for me.
