PC always "hangs" for 4 minutes after rebooting & entering the password, happens after installing Virt-Manager

[Nautical]

Hi and thank you @Nachlese &@linux-aarhus for the replies

I was on a nightmare fueled BIOS ride!

@linux-aarhus

Not that I know much about it - I know that gamers has a habit of doing it - so the question is:

• Have you been setting up gpu passthrough?

Yes, I first tried:
After installing QEMU, it takes 5+ minutes before desktop appears, and GPU passthrough does not work

I got to know that I had to have 2 Graphics cards to be able to do it.
I also learned to always stick to the wiki, tutorials wherever you find them are nothing more than simple guides.
I found an old graphics card, and used it as my main one, and left the Quadro for the virtual machine.

@linux-aarhus

I do believe you have done so - but nonetheless - I have to ask:

• Did you enable AMD-v in the firmware?

That’s why I was away for so long!
I went to Asus’s site hoping to find some answers, and it helped:
[Motherboard]How to set VT(Virtualization Technology) in BIOS and install Virtual Machine in Windows

New users "can/should" not post post links to site as per the rules if I remember correctly
https://www.asus.com/us/support/faq/1045141/

It is not AMD-v! It is SVM mode & “IOMMU”, both of which were enabled.
I changed some other settings in the BIOS & ended up messing a lot of things, hence why I did not reply!

@linux-aarhus

Part of your issue is related to network therefore I suggest you start with disabling and stopping portmaster.

And then there was portmaster-stub. I uninstalled it, and every package started crashing. sudo pacman -Rs and manually deleting what’s in the .config file kind of helped.

That fixed it. After booting & entering the password, the desktop “comes on” quickly.

I moved on to using “yay opensnitch-git” & “yay switchhosts-bin”

@linux-aarhus

Other issues which may cause hang is missing devices or perhaps network service - in any case the target mountpoint does not exist - could be network related - you will likely know.

Since libvirt creates a virtual network - your issue becomes more visible after installing virtmanager and libvirt.

I will always try to avoid tweaking stuff with the network because I am not “practiced” enough to diagnose & solve any issues, so I’ll try to solve everything while keeping the installation of Virt-Manager as “default” as possible.

@linux-aarhus

But it is difficult to guess - try going over my suggestions - hopefully you can narrow down where it happens.

It did

@Nachlese

This should be seen in the CPU flags in the inxi output - but I can’t find it.
It is therefore likely that it is not enabled in Bios/Uefi.

Neither do I, but I have my Windows 10 Virtual machin working very well!

@Nachlese

It also looks like the libvirtd.service gets deactivated for some reason - perhaps for this reason
and quite some time elapses before and after

Removing portmaster-stub fixed it.

Thank you for the support

The idea “of all of this text” is so that if someone might benefit if they were to have a similar issue.
