Re: [Xen-users] HVM systems review

["Derek Sherlock" <derek@xxxxxxxxxxxxxxxx>]

Hi,

 

I've been struggling to get VT working on my new HP d4600y.  Up till this point I assumed the problem was that I was doing something wrong.  But your email makes me wonder whether I just have an incompatible chipset.  Windows' MyComputer/Hardware/Device Manager listing shows:

 

  Intel(R) P965/G965 Processor to I/O Controller - 29A0

 

Does that mean that I should give up on VT?  (If so, I feel rather cheated -- I bought the computer specifically for use with VT under XEN, and if it doesn't work, I've wasted a whole lot of money!)
 

In general, how do you KNOW if your system is VT-capable?  If it doesn't seem to work, how do you know it's the chipset causing the problem?  And how will I make a better informed choice, if I have to buy a different system to replace this expensive paperweight!

 

Thanks,

Derek.

I've done a short study on the current VT options: http://stateless.geek.nz/2006/09/11/current-virtualisation-hardware/

I've got a few issues I'm still trying to determine.

It seems that only the Intel Core Duo 2 desktop chipset that supports VT is the Q965/963.

Has anyone seen support for VT on any of the other 965 chipsets? 
Do any of the non-Intel chipsets (nForce 500?) support VT?


Conversely it seems that all AM2 (desktop) socket systems support Pacifica.

How good is the AMD Athlon 64 X2 CPU is at supporting HVM?
What about the AM2 motherboards. Is there generic out of the box HVM support for all motherboards?  Are some AM2 motherboards better?


PS: http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors should be updated with the new Opteron's.
However it seems the Xeon 5100s are 15% faster than the Opteron 2000s.
