Hello Marek, first of all thanks for all your qualified answers (not only in my but also other threads).

Ok, now I understand, I've read something about qrexec_installed somewhere in the documentation, but I didn't understand in which context this was meant. Yes, I've verified quiagent_installed and qrexec_installed and both are set to False. >> b) can I install the missing Qubes parts later on to get seamless mode >> working and to launch applications from dom0 (qrexec...) > Not easily.

I tried to run Qubes 4.0rc1 on my X230 but ran into problems, as I am now addionally running Coreboot I don't know if this adds even more complexity and thought about waiting until Qubes 4.0rc2 comes out. >> c) is it possible to create a standalone HVM based on an existing Qubes >> template? > Yes, qvm-create --standalone --template TEMPLATE_NAME ... Wow, I didn't know that, I think this is the best approach, as I have the benefits from both worlds: 1) all qubes part to be able to run seamless mode (if needed) 2) all flexibility of a HVM to add additional packages etc. As I want to migrate the HVM later on to vsphere (see my other thread which you have also answered :-) it might be a good idea to remove all specific qubes packages after the HVM has been migrated. *** Question *** Which packages should/can I uninstall to remove the specific Qubes parts (which are not needed after the VM has been migrated)? My HVM which I've build with a standard centos-minimal ISO is now booting up in a window, which is great unfortunately it seems to stuck at boot. I have removed rhgb quiet from GRUB when starting up to see what is going on and the VM is booting up very slowly and is then stucked with the last message: [1.443023] [TTM] Initializing DMA pool allocator I've waited for ~5 min but nothing happens after this. *** Question *** Do you have any idea why the boot is stucket after/at: "[1.443023] [TTM] Initializing DMA pool allocator"  -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
