The 940 will run you about $100 from a recent search of Pricewatch. It is also dual core, which is really helpful when running VMs.
Don't know what to tell you for the chipset, but the Intel chipsets usually do well. Just check out which the computer you are buying has, or just click the right link if you are purchasing the motherboard yourself :)
This is actually what I plan on getting working within the next few months (Unless something better is in the same price range by then).

hi,
for my home "testcenter" i'm searching for a mainboard and CPU to get
xen HVM running. So i still don't need a blade or something else ;-)
What can i buy, without rob a bank?
But please, no via/apollo/sis Chipset :-)

Thanks Steve. For some reason I don't have the CONFIG_ROOT_NFS option in my
kernel.
My problem is much the same as the one described on this page:
http://forums.gentoo.org/viewtopic-t-337239-highlight-.html?sid=f0de502989c707746fcebef76a1267d1
However, I had all the following enabled but still to no avail:
CONFIG_IP_PNP=y
CONFIG_IP_PNP_DHCP=yCONFIG_IP_PNP=y
CONFIG_IP_PNP_DHCP=y
CONFIG_IP_PNP_BOOTP=y
CONFIG_IP_PNP_RARP=y
CONFIG_IP_PNP_BOOTP=y
CONFIG_IP_PNP_RARP=y
I also tried "make CONFIG_ROOT_NFS=y world" and no luck there either.
Thanks,
Ardy

Hi,
based on this message:

kernel domU under 2.6.18 dom0 host now?

I pointed you at an article describing where to enable the relevant
option. The Gentoo page you reference also describes where to enable
the option. Typing random commands and expecting it to work by magic
isn't going to get you anywhere.
Follow the instructions in the Xen README for building a kernel:
# make linux-2.6-xen-config CONFIGMODE=menuconfig
# make linux-2.6-xen-build
# make linux-2.6-xen-install
When you're in the "menuconfig" stage enable:
Device Drivers --> Networking support ---> Networking options ---> IP: kernel level autoconfiguration
Device Drivers --> Networking support ---> Networking options ---> IP: DHCP Support
File Systems ---> Network File Systems ---> Root file system on NFS >
Once you do that you'll have a working system. Simply by following
instructions. No magic!

Hi,
I was wondering if is it possible to perform a "live migration" into the
same host of the original VM.
The reason why ones would like to do this is because at the end of the
"Stop-and-copy" stage of the
live migration process there are two consistent suspended copy of the VM
at both A and B (original and target host),
In cases where applications can afford a downtime on the scale of
nanoseconds this seems to be better option than
doing hot backups (using REDO files at least).
Can anyone shed some light on this?
Thanks

Thanks. I apologize if I was n't clear enough in my previous post. When I
get into the menuconfig stage ( after "make
linux-2.6-xen-configCONFIGMODE=menuconfig" as you also suggested), I
don't see an option for
enabling CONFIG_ROOT_NFS. The Gentoo page also starts by saying this option
did not exist for the user at the menuconfig stage, not until the the
following options were set:
Device Drivers --> Networking support ---> Networking options ---> IP:
kernel level autoconfiguration
Device Drivers --> Networking support ---> Networking options ---> IP: DHCP
Support
However, even by having the above options set, I still do n't have a away to
set CONFIG_ROOT_NFS!
This is my view of options in File Systems -> Network File Systems:
x x <M> NFS file system support
x x
x x [*] Provide NFSv3 client support
x x
x x [*] Provide client support for the NFSv3 ACL protocol
extension x x
x x [*] Provide NFSv4 client support (EXPERIMENTAL)
x x
x x [*] Allow direct I/O on NFS files (EXPERIMENTAL)
x x
x x <M> NFS server support
x x
x x [*] Provide NFSv3 server support
x x
x x [*] Provide server support for the NFSv3 ACL protocol
extension x x
x x [*] Provide NFSv4 server support (EXPERIMENTAL)
x x
x x --- Provide NFS server over TCP support
x x
x x --- Secure RPC: Kerberos V mechanism (EXPERIMENTAL)
x x
x x <M> Secure RPC: SPKM3 mechanism (EXPERIMENTAL)
x x
x x <M> SMB file system support (to mount Windows shares
etc.) x x
x x [*] Use a default NLS
x x
x x (cp850) Default Remote NLS Option
x x
x x <M> CIFS support (advanced network filesystem for Samba,
Window and other CIFS complix x
x x [*] CIFS statistics
x x
x x [ ] Extended statistics
x x
x x [ ] Support legacy servers which use weaker LANMAN
security x x
<M> CIFS support (advanced network filesystem for Samba, Window and other

x x [*] CIFS extended attributes
x x

And the reason I tried "make CONFIG_ROOT_NFS=y world" was the following
post:
http://lists.xensource.com/archives/html/xen-users/2006-08/msg00711.html
I'm no linux/xen expert, but I know this much that there is no magic. That's
why I looked around for a solution.
Thanks to you and others on the list for taking the time to help beginners
like me despite our stupid questions/problems!
