I patched linux-user/syscall.c (see below, branch stable-2.11) which works
around my problem.
So far so good, but the qemu-arm that i compiled is terribly slow compared to
the one that came with Ubuntu 18.04. Any hints?
I configured as this:
./configure --static --enable-kvm --target-list=arm-linux-user
diff --git a/linux-user/syscall.c b/linux-user/syscall.c

Title:
QEMU mishandling of SO_PEERSEC forces systemd into tight loop
Status in QEMU:
New
Bug description:
While building Debian images for embedded ARM target systems I
detected that QEMU seems to force newer systemd daemons into a tight
loop.
My setup is the following:
Host machine: Ubuntu 18.04, amd64
LXD container: Debian Buster, arm64, systemd 241
QEMU: qemu-aarch64-static, 4.0.0-rc2 (custom build) and 3.1.0 (Debian
1:3.1+dfsg-7)
To easily reproduce the issue I have created the following repository:
https://github.com/lueschem/edi-qemu
The call where systemd gets looping is the following:
2837 getsockopt(3,1,31,274891889456,274887218756,274888927920) = -1 errno=34
(Numerical result out of range)
Furthermore I also verified that the issue is not related to LXD.
The same behavior can be reproduced using systemd-nspawn.
This issue reported against systemd seems to be related:
