Всем доброго времени суток!
На одной и той же машине, где все отлично работает на Ubuntu 14.04, лютый же треш на Ubuntu 22.04.
Первый звоночек был - что гипервизор Xen не работает на голой операционке «из коробки». Ядра что идут с ubuntu в комплекте - 6.8.0-40-generic и 6.5.0-18-generic, вообще в паре с Xen'oм не работают без вылетов.
Перебрав с дюжину вариантов, остановился на ядре «6.1.0-1036-oem» с которым получилось добиться стабильной работы Dom0. Но пока тщетны попытки пробросить в гостевую систему любой hardware. Ошибки одинаковые, будь то usb hub, soundcard или gpu.
Конфиг DomU:
#cat /etc/xen/router
builder='hvm'
memory = 1000
name = "router"
vcpus=1
#pae=1
acpi=1
apic=0
disk = [
'file:/media/md0/vm/router_test_ubu24.img,hda,w'
]
xen_platform_pci=1
viridian=1
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'destroy'
boot='c'
sdl=0
vnc=1
vncdisplay=5
serial='pty'
pci = ['08:00.0']
Запускаю:
#xl create /etc/xen/router
libxl: error: libxl_qmp.c:1838:qmp_ev_parse_error_messages: Domain 10:Offset 0x000e:0xffff0080 expands past register size (1)

libxl: error: libxl_create.c:1892:domcreate_attach_devices: Domain 10:unable to add pci devices
Если же в конфиге изменить acpi с 1 на 0, те же грабли только в профиль.
libxl: error: libxl_qmp.c:1838:qmp_ev_parse_error_messages: Domain 11:Bus 'pci.0' does not support hotplugging

libxl: error: libxl_create.c:1892:domcreate_attach_devices: Domain 11:unable to add pci devices
К pciback'у подключены:
# xl pci-assignable-list

IOMMU вроде работает:
# dmesg | grep DMAR

Если вдруг окажется полезным, выхлоп xl info и xl dmesg:

Само собой без строки «pci = ['08:00.0']» в конфиге - зараза работает.. У кого есть мысли куда копать?
p.s. Кидается в глаза строчка: (XEN) Intel VT-d Dom0 DMA Passthrough not enabled.
но в ubuntu 14.04 (4.4.0-124-generic & xen 4.4.2), эта строка идентичная, и passthrough работает..
