Hi Norman,

But first, I think about to
start with a small server. The host provider that I use, use a QEMU with
KVM enable as virtual server. So it is not possilbe to use NOVA on it
because of the KVM enabled featuer (I think) but
Fiasco.OC works.
We added the -no-kvm option in '<build-dir>/etc/build.conf' by default a
few years ago when Qemu/KVM did not implement all the features required
by NOVA. There should be a good chance that NOVA works with recent Qemu
versions. Could you give NOVA on Qemu/KVM another spin and report the
specific problem you encountered?
Ok, I build (after I update to latest master. See below) lighttp with
the NOVA kernel. With 64bit, the vServer reboots every time,
with 32bit the vServer hangs. But with Fiasco.OC it works!
Unfortunately I cannot add any output, it is in a special remote console
from the host provider.
But I added a part of the dmesg output from the Linux rescue system [2].
Maybe somebody can "see" the problem.
In general, I warmly recommend using NOVA over Fiasco.OC as NOVA is the
most commonly used (and thoroughly tested) Genode base platform on x86.
Ok. May I ask the recommended kernel for the following embedded
board Rpi/pandaboard/wand quad ? It looks like there is only
Fiasco.OC, because Fiasco.OC has ARM support, or?
The problem:
So I try to build/create a image from the lighttpd example with Fiasco.OC
kernel. The image started but the lighttpd does not work. Also the
hello tutorial with Fiasco.OC does not work anymore.
I checked the issue tracker on github but I didn't find any
issue about ...
I think that this issue is fixed in the current master branch,
specifically by commit [1]. Prior this change, Genode's core consumed
one additional (dataspace) capability per RPC object when running on
Fiasco.OC, which remained undetected until we added the capability
accounting in 17.05.

Ok, I checked out the lastet master [1]. Now it works. Great. Thank you
for the hint.
This means, master is always stable ? I was expected that the tagged
version is a stable release version.

With Fiasco.OC I get
following error:
Error: nic_drv -> : environment ROM session denied (label="device_pd",
ram_quota=6144, cap_quota=3, diag=0)
I try to add "device_pd" in the boot modules because it is missing in the
rom fs but device_pd is not compile for the Fiasco.OC, only for NOVA.
I found out following in:
genode-src/repos/os/src/drivers/platform/spec/x86/device_pd/target.mk
It looks like device_pd is only build for NOVA.
Admittedly, the log messages look a bit scary but this output is normal
on Fiasco.OC where the platform driver does not support device PDs
(IOMMU). We should probably dim the noise a bit. ;-)
Ok, no problem, I understand :-).
Cheers
