Hi all,
I''m having problems booting a guest OS. I''ve used
xen-2.0.6-src.tgz.
I''ve compiled a 2.6.11.10-xen0 kernel on both Ubuntu 5.04 and Debian
unstable using the stock debian .config files (for 2.6.11). Both of
these attempts worked and allow me to boot into dom0.
The problem is when I try to start a guest domain. LVM2 has been used to
create a root device and a swap device which have both been initialised
and set up (debian bootstrap used to create the root filesystem - all of
the necessary configuration of this guest OS has been done). The
xen config file is as follows:
#***********************************
# -*- mode: python; -*-
kernel = "/boot/vmlinuz-2.6.11-xenU"
ramdisk = "/boot/initrd.img-2.6.11-xenU"
memory = 256
name = "dom01"
cpu = -1 # leave to Xen to pick
disk = [ ''phy:xen/dom01root,sda1,w'',
''phy:xen/dom01swap,sda2,w'']
root = "/dev/sda1"
#************************************
I can start the xend service and query it:
> xm list
Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 123 0 r---- 26.1
However, when I try to start the guest domain using:
xm create /etc/xen/dom01.conf -c
All i see is the following line of output:
Using config file "/etc/xen/dom01.conf".
And the machine locks up. I then have to power cycle it. No errors are
reported in any of the xen log files.
Any help would be greatly appreciated!
Thanx, Marco.

Hi Marco, I''m using a similar setup on Debian with dom0 using sid and multiple domUs using sarge. (Can''t remember why now;)) All domains use kernel 2.6.11.12 (xen testing), but each compiled with different options. [end long story] I haven''t really got any answers for you I''m afraid so hopefully my questions below won''t send you off on a wild good chase!

If you did it manually make sure to do a make ARCH=xen oldconfig (or menuconfig....etc). Did you use a Debianised kernel source for your Debianised config?

Hi Marcus, Answers are scattered throughout the email : ) In short, there is no obvious reason why it doesn''t work. I was thinking today I might try xen testing. Enlightenment is most certainly a long and arduous journey... : ) On Mon, 2005-07-25 at 18:03 +1000, Marcus Brown wrote:> Hi Marco, > > I''m using a similar setup on Debian with dom0 using sid > and multiple domUs using sarge.

In each case I added the Xen stuff to the config file then did a make ARCH=xen oldconfig and removed all the ISA stuff which wouldn''t compile (error: `isa_virt_to_bus_is_UNSUPPORTED'' see: http://lists.xensource.com/archives/html/xen-devel/2004-11/msg00590.html). Following this, from the top-level directory I issue make kernels && make kernels-install.> > >The problem is when I try to start a guest domain.

I should''ve said that it''s a mini-Dell box (Optiplex SX280 if that helps) with integrated everything - including Intel pci graphics. I''ve noticed that intel_agp and agpgart modules get loaded (dom0) at boot time. Knowing that xen-2 and agp don''t mix well, I''ve tried removing them (in fact, I have removed every single non-essential module - and shutdown all non-essential dom0 services) but to no avail (note this is a bare bones debian - no X, no gui, no graphics).> > >name = "dom01" > >cpu = -1 # leave to Xen to pick > > > > > Might as well leave it blank then?point taken : )> > >disk = [ ''phy:xen/dom01root,sda1,w'', > > ''phy:xen/dom01swap,sda2,w''] > >root = "/dev/sda1" > >#************************************ > > > >I can start the xend service and query it: > > > > > > > >>xm list > >> > >> > >Name Id Mem(MB) CPU State Time(s) Console > >Domain-0 0 123 0 r---- 26.1 > > > >However, when I try to start the guest domain using: > > > >xm create /etc/xen/dom01.conf -c > > > > > If you don''t like typing that much: > xm create dom01 > > >All i see is the following line of output: > > > >Using config file "/etc/xen/dom01.conf". > > > >And the machine locks up.

Hi all, A very quick follow up for anyone who might be interested. I''ve since tried the xen-demo cd and FC4 on the same machine and have had the same problems - namely, trying to boot up a guest domain locks the machine up. If anyone is wondering: Dell Optiplex SX280, 1Gb ram, 160Gb SATA disk, Intel i915 integrated PCI graphics, broadcom netXtreme gigE. Booting up a xen dom0 kernel without X works fine. Attempting to boot up a xen domU kernel locks the machine up completely! I''ve been using xen-stable to-date. Next stop - xen testing. Thanx, Marco.
