Re: [Xen-users] Core 2 Duo

[Wong Louis <mylover01ca@xxxxxxxxx>]

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.
ata3: translated ATA stat/err 0x51/20 to SCSI
SK/ASC/ASCQ 0x3/11/04
ata3: no sense translation for error 0x20
ata3: no sense translation for status: 0x51

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.

The VMXON tells you that unmodified guest is
supported. 

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,
