Aaron,

Seems to be something related to your block device.

Try this config file:
name = "Belldandy"
maxmem = 256
memory = 256
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
device_model = "/usr/lib64/xen/bin/qemu-dm"
disk = [ "phy:/dev/SystemsVG/Belldandy,hda,w" ]
vif = [ "mac=00:16:3e:1d:43:df,bridge=xenbr0,script=vif-bridge" ]
vncpasswd='YOURPASSHERE'
vnclisten="YOURDOM0 IP HERE"
vnc=1

Using one of this options:
disk = [ 'phy:/dev/SystemsVG/Belldandy, ioemu:hda,w' ]
disk = [ 'phy:/dev/SystemsVG/Belldandy, sda,w' ]
disk = [ 'phy:/dev/SystemsVG/Belldandy, xvda,w' ]

You can try comment your vif line, maybe is something related to it, and it won't start.

Then, try to connect to vnc server: dom0ip:5900

What's the difference between yours domU config files ? Did you see any other error in xend.log ? If there is no difference at all, try to fsck your lvm partition.

I will give this a look to see if it shed any light on the situation.

> Does the LV show that it's open (or ever changes state) when the VM attempts to boot? Did you try taking a snapshot of the LV and mucking around with the xen configuration to see if anything changes? Did you update anything else on the machine, like perhaps the BIOS? Can you mount the VM's filesystem? Is its partition table okay? How about the boot loader?

- The LV goes to Open when the VM starts and stays that way until the VM
is destroyed
- I have tried messing with the virsh/xen config repeatedly after taking
backups of them
- The host machine has had no hardware or firmware updates applied to it
- I can and have mounted the VM's file systems using kpartx with no
troubles at all
- When I dd'd the LV to a .img file and started it with KVM, the
Bootloader appears as expected

Baffled,
Aaron
