Could you check that memory balancing is not enabled?
It is better to set qvm-prefs [qube-name] maxmem 0 to all windows HVMs

unjust · July 17, 2021, 8:12pm

It is set to 0.
One thing I did with the first HVM where it worked was to install xenvbd.tar and xenbus.tar from the Xen website, then install Qubes Windows Tools from build.
Tried to do that on the new one but now it only hangs on the boot screen.
Guess I have to try yet again with another backup.

According logfile you have real PCI device assigned to qube? Might be a problem?

Also looks like it started correctly and drew window

No needs to do it with QWT-cross version

unjust · July 17, 2021, 9:56pm

Shouldn’t be. GPU passthrough has been my goal all along, and it worked previously. It just halts with this config after 30 sec or so.
I’ve installed QWT 4.1.65 on all my Windows HVM’s.

jevank · July 17, 2021, 9:58pm

In case QWT qvm-feature qrexec needs to be set too.
qvm-features [qube-name] qrexec 1

unjust · July 17, 2021, 10:06pm

Yes, with only qrexec the VM launches, but cannot use USB passthrough.
I had to remove audio-model too, as neither ich6 nor ìch9 worked for me. USB passthrough a headset worked though previously.

jevank · July 17, 2021, 10:15pm

I seem to be confused. What are the symptoms or messages with stubdom-qrexec?

unjust · July 17, 2021, 10:19pm

The giant paste I sent was with stubdom-qrexec 1. It wasn’t that helpful tbh. It just halts after 30 or so secs.
But I’ll keep trying different stuff until it works again.

hackerfactor · July 23, 2021, 12:10pm

I haven’t noticed any sound lag. Then again, my sound card appears as a built-in PCI board and not USB.

rtw · July 23, 2021, 12:51pm

Vey Cool. Thanks

qubesn00b · July 24, 2021, 3:16am

I don’t understand how to do this part. What is the command?

jevank · July 24, 2021, 8:25am

if you are using fedora-based sys-usb run in the template terminal:
sudo dnf config-manager --enable qubes-vm-r4.1-current-testing
sudo dnf update
and restart sys-usb

qubesn00b · July 24, 2021, 10:27pm

How did you get so incredible at all of this? Thank you!

qubesn00b · July 24, 2021, 10:50pm

IT WORKS.

YES IS COMPLETE

HERE IS EXTRA WORDS

This is antire phrase.

unjust · July 26, 2021, 9:32am

Making a Fedora sys-usb sounded like a good attempt, but my hopes were crushed yet again.

stubdom-qrexec 1 won’t boot the VM at all. qrexec 1 boots, but still gives the Failed to open data vchan connection error when attaching USB devices in dom0.
Qubes Copy/Paste in the VM appears to fail after a few pastes also. Had to restart once to paste these few logs.
I have these error logs from my Windows 10 HVM:

I’ve followed a guide regarding patching stubdom to remove the maximum limit of 3.5GB RAM in the HVM. Specifically, this paragraph is added:

# Patch 3.5 Go limit
vm_name=$(xenstore-read "/local/domain/$domid/name")
# Apply the patch only if the qube name start by "gpu_"
if [ $(echo "$vm_name" | grep -iEc '^gpu_' ) -eq 1 ]; then
 dm_args=$(echo "$dm_args" | sed -n '1h;2,$H;${g;s/\(-machine\nxenfv\)/\1,max-ram-below-4g=3.5G/g;p}')
fi

Maybe this could be a source of some issues?

Relevant running processes in Windows 10 are qrexec-agent, qubesdb-daemon, xenagent and XENBUS_MONITOR.

jevank · July 26, 2021, 10:51am

After installing QWT, both features should be enabled.

I can’t help here, never tried this

unjust · July 26, 2021, 4:19pm

It seems to be the RAM limit patch that doesn’t play well with stubdom-qrexec, not the sys-usb template. Setting RAM to 3.5G or below works. Anything above works without stubdom-qrexec, but doesn’t allow me USB passthrough.
That’s a bummer.

jevank · July 26, 2021, 5:10pm

Perhaps you patched wrong file. Look at stubdom-full rootfs, they are different.

unjust · July 26, 2021, 5:19pm

I will try. According to the guide, for R4.1 you need to patch qemu-stubdom-linux-rootfs. Which works, but not with stubdom-qrexec feature.
But I need to patch qemu-stubdom-linux-full-rootfs also?
