Am considering a new laptop, and I wonder if anyone here can share their Xen experiences with the newest Core 2 Duo CPUs, ref http://www.intel.com/products/processor/core2duo/specifications.htm The list at http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors doesn''t include any Core 2 Duos. Does that mean that people have had problems, or is the wiki just not up to date? I gather VT is not available on the T5500 (similar to issues with anything less than the T2300 on Core Duo CPUs). Does the T5600 work OK, or do people here recommend customizing a system with the T7200/T7400/T7600 CPUs?

Dell had (or has) some problems with custumers in China, where it sold Latitude notebooks with T2x00E CPU''s without Intel VT (suffix E).

I don''t know how to get this reply attached to the
thread "Re: [Xen-users] Core 2 Duo". I am browsing at
the archives and there is no help about how to do
thread "linked" reply in the mailing list.
Anyways I have a m7680n (E6400 2M Cache) from HP.
It does have VMX support in bios, even though there is
no "option" of turning it on in the bios, its enabled.
It uses Award/Phoenix bios and the MB is Asus
Broadwater version 3.01 bios by hp. I can''t find any
info on this MB yet. all i865/ICH8 chipset like
broadwater is from P5W deluxe, but the MB is a bit
different, the name is p5Wla or something, check hp
website. The SATA DVD drives is not supported
properly with the linux-2.6.16.13 kernel that xen
uses. but works fine with the 2.6.17 (or mm4)...but I
can''t patch that to work with xen... so no SATA dvd
rom for me yet.

After you compile the kernel with I think P4 support,
you will see the vmx flag in the cpuinfo. then I get
the mercurial to get the unstable hg.

Getting the CDROM ISO to work was not easy because of
changes in the configuration files that is not updated
in the user manual. Its all now placed in "disk"
section. (so just comment/delete the "cdrom" section)
disk = [
''file:/root/w/w.img,ioemu:hda,w'',''file:/root/w/i.iso,hdc:cdrom,r''
]
The networking part is so diffuclt, I still can''t get
online on the vm.. I am connected with wlan0 (no
eth0.. the xen always thinks eth0.. (house is
completely wireless...) and I don''t know what file to
change to force it not load it). Now I don''t want to
use bridging, but xen forces me to??, (even with
rtl8139 (with the vif=''ioemu''... reply if you need
more info/interested) and vif-nat doesn''t work for me
(yet?), I will post a reply if I can get it to work.
I tried also with pciback unbinds, etc but it doesen''t
work, the winxp doesn''t detect the card. I think its
for linux domU guests only.
I am using xen unstable,

Hi, I have a IBM/Lenovo Thinkpad T60p with a core-duo, it works great. There is an option in the BIOS to enable or disable the VT extension. The machine is really great, I switched from a Dell Inspiron 8200, a piece of S**t, after having my motherboard changed 4 times, video card 2 times, DVD-CDRW changed once, HD changed once, power supplies changed once, modem changed once, and finally they had to change the case because it broke from having opened it so many times.... Anyways, the Thinkpad construct and quality is really good. I recommend it, I had expected it to cost a lot but it cost the same price as my Dell did. I have a 2GHz T2500.

The processors that support the VT depend on the procssor model. From the intel website the following are supported: T7600 - Does T7400 - Does T7200 - Does T5600 - Does T5500 - Doesn''t T2700 - Does T2600 - Does T2500 - Does T2400 - Does T2300 - Does T2300E - Doesn''t L2400 - Does L2300 - Does U2500 - Does T1400 - Doesn''t T1300 - Doesn''t U1400 - Does U1300 - Does Hope this helps.
