Hi all, I'm not a developer but I would like to set up my Xen system to |
| 2 |
get bug reports as useful as possible. At present I am logging the xen |
| 3 |
console via serial port, and I am running Xen compiled from gentoo |
| 4 |
ebuild with "debug" use flag. Is there anything more I need to set up to |
| 5 |
be able to collect as much useful info as possible? |
| 6 |
|
| 7 |
At present, this is my xen command line: |
| 8 |
xen_commandline : ssd-xen-debug-marker console_timestamps=date |
| 9 |
loglvl=all guest_loglvl=all sync_console iommu=1,verbose,debug |
| 10 |
iommu_inclusive_mapping=1 com1=115200,8n1 console=com1 dom0_max_vcpus=4 |
| 11 |
dom0_vcpus_pin=1 dom0_mem=8G,max:8G cpufreq=xen:performance,verbose |
| 12 |
tmem=1 sched_smt_power_savings=1 apic_verbosity=debug e820-verbose=1 |
| 13 |
core_parking=power |
| 14 |
|
| 15 |
(yes, I know, 8G for dom0, well, it is also acting as file server, I |
| 16 |
want to keep as much of the file-system in cache as I can ) |
| 17 |
|
| 18 |
Any changes I should make for maximally useful bug-reports? |

This is in preparation for the 4.7 release (april 2016 I gather) . I |
| 21 |
have some PCIe cards that are acting up, something to do with |
| 22 |
interrupts. I see some activity on that front right now, so I've decided |
| 23 |
to be an early adopter of 4.7, to be able to help as much as possible, |
| 24 |
maybe get any tweaks I might need for my system done in the source. |
| 25 |
|
| 26 |
I'm running gentoo, and have tried installing xen-*-9999 from the |
| 27 |
virtualization overlay, but it fails, seems it is trying to fetch the |
| 28 |
qemu sources twice, and failing. Is it me doing something wrong? Use |
| 29 |
flag "system-qemu" does not help. |

Additional info: |
| 33 |
The PCIe cards that are acting up are: |
| 34 |
00:1b.0 Audio device: Intel Corporation C610/X99 series chipset HD Audio |
| 35 |
Controller (rev 05) |
| 36 |
02:00.0 USB controller: ASMedia Technology Inc. ASM1042A USB 3.0 Host |
| 37 |
Controller |
| 38 |
81:00.0 USB controller: ASMedia Technology Inc. Device 1242 |
| 39 |
|

Trying to pass them through to any domain is highly hit-or-miss. Seems |
| 41 |
like interrupt set-up fails quite often, but I have not been able to |
| 42 |
find any actual error-messages in any logs. The two first there are |
| 43 |
built-in to the motherboard, the last one is an add-in card. I have |
| 44 |
tried several other add-in cards for USB, all acting decidedly weird. |
