QA » openQA Project

I'm trying to run the openQA under RHEL 7* using the docker container with Fedora (so I have the RHEL host and Fedora docker's image with openQA installed). When I'm posting the job using the /usr/share/openqa/script/client jobs post DISTRI=ubuntu Version=18.04 ARCH=x86_64 TEST=TC MACHINE=super64bit ISO=ubuntu_tos.iso command the job is stuck on BIOS (see 1'st screenshot and log files). But when I'm posting the job with QEMU_NO_KVM=1 parameter the test starts working, but very slowly.
I checked whether my system supports KVM using the next few commands with results:

[root@openqa /]# egrep -c '(vmx|svm)' /proc/cpuinfo
8

[root@openqa /]# egrep -c ' lm ' /proc/cpuinfo
8

[root@openqa /]# uname -m
x86_64

[root@openqa /]# ls -l /dev/kvm
crw-rw-rw- 1 root kvm 10, 232 Jun 26 09:24 /dev/kvm

[root@openqa /]# lscpu | grep Virtualization
Virtualization:                  VT-x
Virtualization type:             full

[root@h0006104 niz118]# lsmod | grep -i kvm
kvm_intel             188688  0
kvm                   636965  1 kvm_intel
irqbypass              13503  1 kvm

So it looks like the KVM acceleration can be used.
My docker container is running in privileged mode inside the host network. But the most strange is that the same docker image with the same job's parameters is correctly (without QEMU_NO_KVM) running under my local Fedora host (instead of RHEL). Host with Fedora has the same KVM setup.

I know that it is better to use openQA without docker but it is difficult to install it on RHEL due to versions incompatibilities.
