Cannot launch hart RT UOS when running Ubuntu as SOS

Alfonso Sanchez-Beato
Hi,
I have set-up Ubuntu as service OS by following the instructions in https://projectacrn.github.io/latest/tutorials/using_ubuntu_as_sos.html. ACRN is recognized as hypervisor and all looks good in principle. However, after that I followed the instructions on how to start an RT UOS and things fail: $ sudo /usr/share/acrn/samples/nuc/launch_hard_rt_vm.sh
cpu1 online=1
cpu2 online=1
cpu3 online=1
pm by vuart node-index = 1
SW_LOAD: get ovmf path /usr/share/acrn/bios/OVMF.fd, size 0x200000
vm_create: hard_rtvm
VHM api version 1.0
failed to create VM hard_rtvm
The kernel output is: [ 1530.397790] smpboot: CPU 1 is now offline
