[help] Xen 4.14.5 on Devuan 4.0 Chimaera

[tachyon_gun@xxxxxx]

Hello.

Following the advice of Andrew Cooper (thanks for helping out) over on OFTC.net in #xen, I'll post this here.
If this is the wrong place, please move it to the right section of your mailing lists.

 

I got some problems running Xen 4.14.5 on Devuan 4.0.

 

The AMD-Vi and I/O virtualisation are not being enabled when booting up the host system with Xen.

 

Hardware used:

Mainboard: Gigabyte GA-890FXA-UD5, BIOS version F6 (2010.11.24, the latest version)

CPU: AMD Phenom II X4 910e

Memory: 16GB

Storage: 2TB Crucial MX500

 

A short snippet of what I see when invoking "xl dmesg":

 

(XEN) No southbridge IO-APIC found in IVRS table
(XEN) AMD-Vi: Error initialization
(XEN) I/O virtualisation disabled 

 

What I would like to see (taken from Xen 4.0.1 running on Debian Squeeze, in use since 2011):

 

(XEN) IOAPIC[0]: apic_id 8, version 33, address 0xfec00000, GSI 0-23
(XEN) Enabling APIC mode:  Flat.  Using 1 I/O APICs
(XEN) Using scheduler: SMP Credit Scheduler (credit)
(XEN) Detected 2611.936 MHz processor.
(XEN) Initing memory sharing.
(XEN) HVM: ASIDs enabled.
(XEN) HVM: SVM enabled
(XEN) HVM: Hardware Assisted Paging detected.
(XEN) AMD-Vi: IOMMU 0 Enabled.
(XEN) I/O virtualisation enabled

 

My question would be if this is "normal" behaviour due to older hardware being used with newer versions of Xen (compared to the old 4.0.1) or if this is a bug.

If the latter, has this been addressed already in newer version (4.14+)?

 

I'll attach some log files (hypervisor.log, dom0.log, xl_info.log, lspci_vvv.log, acpi.dmp, ivrs.dat, ivrs.dsl).

 

Thank you for your time.

 

Kind regards, 

Denis
