I am planning to buy a new laptop.
a) Do anybody have idea which laptop will be suitable for such task,
Like high processing
shows {Intel? Virtualization Technology (VT-x) ?== ? ? ?No} . is it the
same vmx flag ?? because I have a netbook with ATOM z520
http://ark.intel.com/Product.aspx?id=35472&processor=Z500&spec-codes=SLB6Q
which shows a vmx flag. but in the above link, it show it do not have
{Intel? Virtualization Technology (VT-x) }
ensure that the virtualization is enabled in CMOS.
I was in the same quandry a few months back looking for a laptop on
which I could run the Linux KVM.
In my research, I learnt the following:
(a) it is not sufficient that the laptop CPU has VT-x or AMD-v
capability - the BIOS must have a Virtualization setting or not
preclude VT-x/AMD-v usage.
(b) On the Intel front, only the more expensive models have CPU with
VT-x but ... most of them come with a b0rked BIOS that prevents the
loading of KVM modules.
(c) On the AMD front, I could not find much information
Ultimately, I really **lucked** out when I bought the ACER Aspire 5542.
The BIOS, even though there is no Virtualization setting, does not
preclude the loading of KVM modules. It is a minor irritation which
can be fixed with a small script.
c) buying a laptop, with Graphics card with 1GB/512MB memory, How does
it help in performance.
It depends on what *you* want out of the system. Are you into
playing games, developing games and/or animation? Then fork out the
money for dedicated graphics memory.
On the 5542, The performance of the graphics is nothing to write home
about though, even with the proprietary ATI drivers - but to me KVM
was more important than graphics performance.
