![]() ![]() This is fixed in F3 CPU's.ĪMD tool can apparently confirm the problem: Mention of F2 virtualization issue at Microsoft's technet forum:į2 CPU's have a hardware problem and require BIOS support to workaround the issue. I have BH-F2 revision, so it may mean that it could be CPU issue that BIOS is just not covering, i.e. Until recently I was unaware of the fact that AMD F2 stepping has buggy virtualization. (Similarly to my #2061, where faghutz came with Mac OS X problem.) But ad rem. It was closed after bvkchaitanya came with other than predecessors' problem, that should have its own issue actually. The issue was going to cover AMD virtualization problems. OS/2 is working in Parallels Workstation too, so my OS/2 copy is good. But it is working fine in Microsoft Virtual PC - with and without hardware virtualization. I wasn't succeed - OS/2 freezes at startup screen. I suspected that hardware virtualization is enabled in VBox only when needed, so I tried to install OS/2. ![]() I installed VirtualBox 1.6.0 - 1.6.4 and I found that VT-x wasn't working too. I found that almost 1/2 of them was missing VT-x, because of strange motherboard problems, but some of them were working properly with VT-x enabled in Parallels Workstation and Microsoft Virtual PC 2007. Then I guessed that VBox don't work properly with AMD SVM, so I tested it on several Core 2 Duo systems with Intel VT-x. I suspected that my motherboard or my CPU for some weird reason is not working properly with VBox, so I tried it on my other computers - the result was the same: hardware virtualization wasn't working at all with VBox, but it was working very well with VMWare Workstation, Xen, Parallels Workstation. Then I tried several other OS that I already have installed on my PC - both 32 and 64 bit - the situation was the same: I enabled the option, but in running VM I found that it's disabled. I am using VirtualBox in my home for testing purposes and after some time I found that I can't make hardware virtualization to work with my main home computer. In my work I am using several virtualization products - VMWare ESX, VMWare Server, Parallels, Xen, Microsoft Virtual Server, Microsoft Virtual PC, linux vserver and some other. Yes, I have multiply boot machines in my home and a lot of servers and workstations at my work - I already said I am System Administrator, I am not an ordinary user. ![]()
