i'm having this problem to start any xen HMV on my debian server:

root@server /h/l/Documentos# xl create vm.cfg
Parsing config from vm.cfg
libxl: error: libxl_dm.c:2427:device_model_spawn_outcome: Domain 20:domain 20 device model: spawn failed (rc=-3)

libxl: error: libxl_domain.c:920:domain_destroy_cb: Domain 20:Destruction of domain failed

In the logs appear:

My system is a:

My Xen configuration file points to:

name='vm'
type='hvm'
vcpus='4'
memory='4096'
disk=['file:/media/STORAGE01/ISO/vm-linux-kde-2019.2-amd64.iso,hdb,cdrom,ro' , '/dev/vm01/vm,raw,hda,rw']
boot='dc'
_on_poweroff_='destroy'
_on_reboot_='restart'
bios='seabios'
bootloader='pygrub'

I remember pygrub is for pv domains only. Can you confirm hvm domus can use that as bootloader?

serial='pty'
kernel='/boot/vmlinuz-4.19.0-5-amd64'
ramdisk='/boot/initrd.img-4.19.0-5-amd64'
device_model_version='qemu-xen'
device_model_override='/usr/lib/xen-4.11/bin/qemu-system-x86_64'

'device_model_override' requires xen to be built with qemu-system support. Can you confirm your installed packages have that support?

see: https://wiki.xenproject.org/wiki/QEMU_Upstream

vif=['ip=XXX.XXX.XXX.XXX','mac=XX:XX:XX:XX:XX:XX','bridge=xenbr0']
vnc='1'
vnclisten='XXX.XXX.XXX.XXX'
vncdisplay='0'

I've found several threads suggesting a diversity of approaches, none of them worked.

Update: It also appers to be releated with these logs too:

11/09/2019 00:40 lucifer /etc/xen/scripts/block: remove XENBUS_PATH=backend/vbd/24/768

And this very suspicious:

10/09/2019 22:45 xen en_evtchn: Event-channel device installed

10/09/2019 22:45 IPv6 ADDRCONF(NETDEV_CHANGE): xenbr0: link becomes ready

That led me to check

root@server:/# systemctl status -l libvirtd

lines 1-21/21 (END)

And hat makes me think that there is something wrong with the NIC device or its module; the bridge seems ok:

root@server:/# brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.e0d55ef46d39 no enp6s0

any ideas?
