You pretty much did everything correctly. If it still refuses to come
up the only available option is restore from backup.

I see that you use losetup, meaning file-backed storage for domU. Do
you also use file:/ in domU config file? If yes, then that
configuration is prone to failures. You should use tap:aio:/ or phy:/
with LVM-backed storage.

Hi Fajar,

I got the commands via google search, so I didn't know that losetup was only meant for file-backed storage.

Here's the domU configuration:

[root@xen ~]# more /etc/xen/hfserver2
name = "hfserver2"
uuid = "073b87c5-0317-6eb3-f07f-b8978246ec48"
maxmem = 4096
memory = 1024
vcpus = 2
bootloader = "/usr/bin/pygrub"
>> >vfb = [ ]
disk = [ "phy:/dev/data/hfserver2,xvda,w" ]
vif = [ "mac=00:16:3e:2d:a1:fe,bridge=xenbr0" ]

Unfortunately there's no backups :(
