RE: [Xen-users] Building from Source
Are you using this config file for your domu?
name = "lb1"
builder = "hvm"
memory = "512"
device_model = "/usr/lib/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
#disk = ['phy:/dev/loop0,hda,w']
boot="c"
acpi="0"
serial = "pty"
vncpasswd = "test"
I found this in one of your previous emails to the list. I used this
to see if I could replicate your problem. Using the config file for
domu that you supplied I get the exact same results on a working
xen3.3 box.
You are trying to use the loop device for a disk for a hvm machine.
You are using 'boot="c"' when there is nothing on the "disk". You need
a line like this:
disk=['phy:/dev/rootvg/nathan,hda,w','file:/home/jonr/nevaeh-i386.iso,hdc:cdrom,r']
I am using your config file and booting just fine. Your problem is
your "disk=" line in your config file. I am using LVM's in this
example but you could also use file based "disks".
When I use the config file you supplied on the list I get the exact
same errors in /var/log/xen/qemu-dm-lb1.log.
You do not want to use /dev/loop0 as a disk.

Jon,
I guess I didn't explain clearly...
I cannot get a DomU to stay in a running state. It doesn't matter
if there is a disk attached or not, the DomU dies almost instantly.
Thank You,

Jon,
As I mentioned - the disk line seems to have no effect on whether or
not the DomU boots. Even with no disk line, I get the same
results. The loop device was just a temporary contrivance for
testing, but is definitely not the cause of the issue.
Nathan,
Using your config file I can get the same results on a known working
dom0. Whether I have the disk line in or not, when I boot the domu
this is what I see:
root@xenproof:/etc/xen# xm create nathan
Using config file "./nathan".
Started domain lb1
root@xenproof:/etc/xen# xm list
Name ID Mem VCPUs State
Time(s)
Domain-0 0 2367 2
r----- 2073.1
domutest 12 512 1
r----- 3662.0
Is this what you are seeing as well?
What OS is on loop0? Did you already install an OS onto that device? I
went back through the archives and couldn't find the email that said
you had already done that. I may have missed it though.
Jon
