Why is the new DomU not starting - CentOS 7. HVM?

Question

linux

Good day. I installed the CenOS 7 guest domain in hvm mode. How I installed it: 1) I created an LVM partition, all the guest domains on LVM work for me there. 2) Config during installation:

[[email protected] xen]# cat Centos7.hvm 
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
name = "Centos7"
memory = "1024"
disk = ['phy:/dev/mapper/VolGroup00-Asterisk,hda,w', 'file:/mnt/usb_HHD/CentOS-7-x86_64-Everything-1503-01.iso,hdb:cdrom,w']
vif = ['type=ioemu,bridge=avpublic']
device_model = "/usr/lib64/xen/bin/qemu-dm"
boot="d"
vnc=1
vcpus=1
serial = "pty"
on_shutdown = "destroy"
on_reboot = 'destroy'
on_crash = "preserve"
[[email protected] xen]#

Installation goes great, no errors.

2) Config after installation:

[[email protected] admin]# cat /etc/xen/Centos7.hvm 
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
name = "Centos7"
memory = "1024"
disk = ['phy:/dev/mapper/VolGroup00-Asterisk,hda,w']
vif = ['type=ioemu,bridge=avpublic']
device_model = "/usr/lib64/xen/bin/qemu-dm"
boot="c"
vnc=1
vcpus=1
serial = "pty"
on_shutdown = "destroy"
on_reboot = 'destroy'
on_crash = "preserve"
[[email protected] admin]#

A crash occurs at startup, and if the on_crash = “preserve” parameter is in the config, then the state is saved and it is possible to find out what it told us before death, otherwise it just cuts it out. And this is what is output before the crash: Crash . Tell me what's wrong?
