Some additional information about the case.
Infra at the moment has a limitation in one VM per jenkins job. So we are
not able to launch two VMs and boot one of them via PXE from another. We
need to start VM and then start another nested VM inside first one.
Besides, nested VM must be qemu, not kvm. It is because donated cloud
resources used for testing do not support hardware nesting.
