I was able to make further tests in the time available.
the result did not go well, but some doubts came.
Summary:
QWT (working and correct resolution!) Ok
UEFI boot OK
stubdom-linux-rootfs.gz *(only Dom0 starts) KO*
even with only Dom0 started and giving 12gb Ram the VM windows goes wrong.
with the fix stubdom-linux-rootfs it only works for me Dom0, so I
immediately restored it.
_________________________________________
I saw that the ATI Radeon card shares the IRQ 16 with these others:
00: 01.0 PCI bridge: Intel Corporation Xeon
00: 1a.0 USB controller: Intel Corporation 7 Series / C216 Chipset Family
USB Enhanced Host Controller # 2
00: 1c.0 PCI bridge: Intel Corporation 7 Series / C216 Family PCI Express
Root Port Chipset 1
But if I try to connect one or all the devices to the HVM, these (besides
the vga radeon) I always get:
... has failed to start: internal error: PCI end devices can not be
assigned to guest
1. I MUST also exclude these devices at startup in EFI.cfg ???
all devices that share the same interrupt ??
2. in lspci -t (show bus tree) which means this representation ??
(*+ -01.0- [02-03] ---- 00.0*) ??
sudo lspci -vt
- [0000: 00] - + - 00.0 Intel Corporation 3rd Gen Core processor DRAM
Controller
+ -01.0- [02-03] ---- 00.0 Advanced Micro Devices, Inc. [AMD /
ATI] Thames [Radeon HD 7550M / 7570M / 7650M]
3. is the kernel driver loaded on the card no good? (*Kernel modules:
radeon) *
4. In the conclusions of the guide, where can I find more info to try with
libvirt and libxl ??
"If it doesn’t work and you need to debug more things, you can go deeper.
Virsh (start, define, ...)
/etc/libvirt/libxl/
xl
/etc/qubes/templates/libvirt/xen/by-name/
/usr/lib/xen/boot/
virsh -c xen:/// domxml-to-native xen-xm /etc/libvirt/libxl/..."
*Thanks to those who want to explain these doubts.*
