Can't create 64-bit guest after upgrade to VMware8

anon209 · 10-26-2011, 06:44 PM

After upgrading to VMware8 I am no longer able to create a 64-bit Guest, Instead I receive 2 errors;

Code:

Software virtualization is incompatible with long mode on this platform. Disabling long mode. Without long mode support, the virtual machine will not be able to run 64 bit code. For more details see http://vmware.com/info?id=152.

and

Code:

This virtual machine is configured for 64-bit guest operating systems. However, 64-bit operation is not possible.
Longmode is disabled for this virtual machine.
For more detailed information, see http://vmware.com/info?id=152.
Continue without 64-bit support??

I have verified in the BIOS that VT-Intel is Enabled as well.
Has anyone else run into any issues running 64-bit guests with VMware8?

TIA

Which CPU are you using.
The error states that your CPU does not have 64bit extensions.

There are CPUs that do have hardware virt. extensions, but not 64bit capable - such as the Intel T2500 http://ark.intel.com/products/27236/...Hz-667-MHz-FSB)

Anyway, I rolled back to the previous version, as with this new version I can't mount anymore my "real hard drive" (I share my native linux partitions with my VM on windows Host, because it's SOOOO easier and cool)...

Last VMPlayer might be good for some points but this huge regression stop me to do the jump (I was happy to still have the previous version on my disk

).

It's sad somehow because I wished I could have benefit from OpenGL optimizations....

Btw, I didn't try to install a new VM with it, and I already had problem trying to install freeBSD 64bit (only the 32bit version works)...

Slack64 13.37 works very well on the previous version.

disturbed1,

I have the Intel 5 Series (i5) processor, what I don't understand is that I had no issues with VMware7 but now I do, with 8. I am unable to run any 64-bit Guest OS.

Not really sure then. There are some threads at VMware communities with the same subject, but most are solved with enabling VT in the bios, or upgrading the bios.

64/32bit guests work fine here on Slackware64. Both newly created guests, and previously created guests. I'm using Workstation 8.0.0 build-471780.

I'm getting the same thing with the Intel DX58SO motherboard.
This motherboard is aggravating me for a number of reasons, and I think I will be trying an Asus P6T Delux v2.
It's what I have on my main pc, the other being a newly-created "sacrificial" PC, although it is rapidly becoming a Money Pit PC.
I may well be TOTALLY off base blaming the MB, so take this for what it's worth.
Also, I realize this is a Linux board, and I have a Windows host in this case. I originally wanted an Ubuntu host on this PC, but the motherboard was giving me such a hard time, that when I finally got Windows to install, I just let it go.
I have no idea what's with this motherboard.
If I get really gungho by the time the board comes in, maybe I'll go back to my original plan.
In any event, I am also NOT a big fan of VMWare 8, and may also just go back to 7.
It all remains to be seen.
Don't these guys just crack you up with some of their responses? Not mentioning any names.....
PS....My configuration is similar to yours...i7 920; processor worked fine in the Asus MB with VMWare 7. What MB are you using? Also part of my warning message said, in addition to enabling virtualization to DISable ...what was it?.....I forget...."Allow trusted executables?" Something like that....I'm doing this from memory, and it's going fast!
