[Xen-users] Unable to start domUs on Xen 3.0.2+hg9697-1 (Debian amd64)

[Rob Andrews <rob@xxxxxxxxxxxxx>]

I'm having trouble with starting domains under Xen 3.0.3+hg9697-1 on my
Debian amd64 machine.

The hypervisor and dom0 kernels are booting fine. Once booted, the xm
list output looks like:

# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0      123     1 r-----    45.2

So, I booted the latest FC6 (pre 5.91) x86_64 media and made a small
installation to an LVM group, then chrooted into it and installed the
kernel-xen package from the DVD - then copied the kernel and initrd back
to somewhere the Debian xen0 could get to them.

Upon returning to the Debian-xen0 system, I prepared the config file:

# cat /etc/xen/fedora
name = "fedora"
kernel = "/boot/vmlinuz-2.6.17-1.2517.fc6xen"
ramdisk = "/boot/initrd-2.6.17-1.2517.fc6xen.img"
memory = 512
disk = [ "phy:mapper/group01-fedora,sda1,w" ]
root = "/dev/sda1 ro"
vif = [ "" ]
on_crash = "preserve"

(n.b. I put 'on_crash = "preserve"' to stop the domain constantly
restarting)

Now, when starting the domain, I get:

# xm create fedora
Using config file "/etc/xen/fedora".
Started domain fedora

And xm list gives:

# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0      123     1 r-----    46.3
fedora                            11      512     1 ----c-     0.0

i.e. It crashed immediately.

If I perform 'xm create -c fedora', no additional output (i.e. kernel
messages) are output, and it just sits there until I hit ctrl+].

The setup is:

||/ Name                     Version
