Re: help [ In reply to ]
Well, I believe, you shall start from some books about xen. Without
consistent xen knowledge you will often see some 'strange things'.

Really cool book is Definitive Guide to Xen. But be ready to very
concentrated book. The Xen boot (practical guide) is not very good, but
much easy to read.

Other way is using XenServer/XCP with XenCenter or OpenXenManager (lame
windows way for people who wish 'do it somehow and forgot').

... and third, really hardcore way, is learn xen/xend sources [the path
of the god].

This is one of the many reason why you should always start a new thread
by pressing the "New" button in you MUA and not replying to an existing
mail.

You'll want to change your password now I expect.

I think this is a message from grub, but without a full boot log it is
hard for me to tell.

What have you tried?

Please provide the grub menu entry you are using. Why aren't you just
letting update-grub generate one?

Are you perhaps trying to boot EFI Xen from GrUB? Don't do that, instead
launch xen.efi directly from the UEFI shell. See
http://xenbits.xen.org/docs/unstable/misc/efi.html and various threads
on -users@ and -devel@

> Does Xen require any specific hardware configuration?

Not especially, this is almost certainly a s/w issue.

Ian.

I'm afraid these are not what is needed, I asked for the "boot logs"
which means the logs which are printed when booting (or failing to
boot). Since your boot is failing it is very unlikely that those logs
would make it in to /var/log. That probably means using a serial console
or taking a photograph of the failed boot.

Please provide the stanza anyway.

Does your system have an EFI BIOS firmware? If yes then perhaps
update-grub is not generating valid entries for this case, in which case
you should refer to the docs I linked to, or figure out how to configure
your BIOS to do a "legacy" boot.

Ian.

Hi Sara,

Let me ask you a bunch of questions to make sure I understand your setup
correctly.

Could you please send me the host device tree that you are using
(i.e. xen.dtb), the VM config file for the DomU (createdom1.cfg) and the
partial device tree for the Domu? (I can't access the files you attached
to your original email.)

Also, what version of Xilinx Xen are you using?


For your information, I know of a potential issue with the LWIP
baremetal app on Xen. It manifests with warning messages like the
following on the Xen console:

No access to MMIO read ff5e005c, which is gem3's REF CTRL register address

Have you seen anything like it by any chance? If so, I know the solution
to the problem.
Re: help [ In reply to ]
Hi,

I attach to this email all the files I use for booting xen and dom1, and
the xen.dtsi. The version of Xen I use is 4.11.1 and the version of SDK I
use is 2019.1. I don't get any warnings in Xen console.
But when I create the SDK lwip application I get two error messages:
"region 'psu_ddr_0_MEM_0' overflowed by 34623488 bytes" and "client.elf
section '.bss' will not fit in region 'psu_ddr_0_MEM_0'". I solve these
errors by resizing the 'psu_ddr_0_MEM_0' in lscript.ld to 35MB. I don't
know if this has something to do with my problem.
Then I don't get any message in Xen console when I boot domU.
Thank you,
Sara

Re: help [ In reply to ]
Looking at your DomU configuration (dom1.cfg), you are missing the
following line which is necessary for a correct SMMU setup:

dtdev = [ "/amba/ethernet@ff0e0000" ]

See the following docs with longer explanations:
