Hibernation is not supported by Xen, so it's probably not supposed to
work. However, suspend (S3 sleep) is supported.

I am trying to watch  Qubes OS: The Operating System That Can Protect You
Even If You Get Hacked and the other videos on the qubes website with tor
browser (on non qubes os). I see that youtube has this video but even in

[qubes-users] VM won't start if Realtek PCI card reader is assigned to it (even if removing conflicting Ethernet controller)

['Davide' via qubes-users]

*Qubes version*

Qubes-R4.0.1-x86_64


*Affected component(s) or functionality*

02.00.0: Realtek PCI Express Card Reader RTL8411B vs.

02.00.1: Realtek PCI Express Gigabit Ethernet controller RTL8111/8168/8411

---

*Steps to reproduce the behaviour
*

1. From sys-usb Qube Settings (or any other qube), section Devices, 
attach device 02.00.0 (card reader).


2. Start sys-usb (or other qube).


*Expected or desired behaviour*

The VM will start and card reader device is available.


*Actual behaviour*

The VM won't start. An error message appears: "qrexec-daemon startup 
failed: Connection to tthe VM failed".



*General notes
*

The same problem occurred right after installation with my Ethernet 
controller in sys-net. In that case I managed to get sys-net started 
(with my Ethernet controller working) by following suggestions in issue 
#1393 . Assign both 
Ethernet controller and card reader to sys-net did not work, but 
removing card reader did (/echo -n "1" > 
/sys/bus/pci/devices/:02:00.0/remove/).


I thought I could do vice versa to get card reader working, but in this 
case I had no luck. I tried in vain:


- removing Ethernet controller (/echo -n "1" > 
/sys/bus/pci/devices/:02:00.1/remove/).


- attach card reader with no-strict-reset (/qvm-pci a work dom0:02.00.0 
--persistent -o no-strict-reset=true/)


- attach it with permissive mode (/qvm-pci a work ///dom0:02.00.0/ 
--persistent -o no-strict-reset=true/).

[qubes-users] Why is there no option to save VM state?

[Guerlan]

In KVM with Qemu I used a lot of VM state saving, where I could save the 
entire VM to disk and restore that. Since my SSD is very fast that only 
took 5 seconds in average, so it was very useful. Specially, since I cannot 
put my laptop to sleep and hibernate wont work either, my only option was 
to be able to save VM state, but I don't see any way of doing it.

Is it possible or is it a feature to be implemented?

When I press hibernate, nothing happens. Was it supposed to work? If so, 
how can I debug what's happening?

[qubes-users] OS/2 on Qubes

[Robert Kuropkat]

I just installed Qubes and and was hoping I could install OS/2 as a 
guest.  I have a collection of VirtualBox VMs as well as original 
media.  I tried following these directions (even though they were for a 
Windows VM):


https://www.qubes-os.org/doc/standalone-and-hvm/#converting-virtualbox-vms-to-qubes-hvms

As mentioned though, it was not a Windows VM, but an OS/2 VM. Also, it 
was not a vmdk file type, but a vdi.  At first, it almost looked like it 
was working, then the VM stopped with a message that it could not 
operate the hard disk.


I also tried install from original media using these directions:

        https://www.qubes-os.org/doc/windows-vm/

Again, the media started up, but then hung and refused to continue.

Thanks awokd, you gave me more hours of tweaking and still a lot of hope.

I didn't think QWT was necessary.

The mystery of how to modify the configuration xml remains.

See you soon for updates.

Thanks for the advice awokd. I was able to get R4.0.2-RC1 installed. 

I worked around the Debian template update issue by using 'apt update'
manually in the terminal.  The default installed Fedora, Whonix and
Debian templates seem to update from Qubes Manager normally.

I've had issues after restoring my backups though. I can't seem to
upgrade my TemplateVMs without getting the dreaded “Failed to
synchronize cache for repo” errors
https://www.qubes-os.org/faq/#i-keep-getting-failed-to-synchronize-cache-for-repo-errors-when-trying-to-update-my-fedora-templates
Switching the NetVM for the templates between sys-whonix, sys-firewall
and sys-net hasn't resolved the error. I guess that is a Fedora issue
rather than Qubes though.

[qubes-users] [VPN GUIDE] - ProxyVM loses internet connectivity after first restart

[Rafael Reis]

Hey folks. I've been trying to achieve VPN connection for a couple of days 
now. 

As soon as I create or clone a NetVM (AppVM + provides network or cloning 
sys-net), on the first boot I'm able to implement, connect and test 
everything normally. 

After the first reboot I lose completely Internet access on the NetVM, 
rendering the VPN Gateway useless.

Followed both the guide in the doc (https://www.qubes-os.org/doc/vpn/) and 
also https://github.com/tasket/Qubes-vpn-support, with exact same 
unsuccessful results - works on trial run before reboot, but no Internet 
access after reboot. To be clear, that is before trying to establish vpn 
connection.

I tried pointing them to use sys-net or sys-firewall as NetVM, rebooting, 
and no connection comes up. 

I'm a dedicated researcher, browsed around quite a bit already but could 
not find resources to help me. 

I'm running a freshly installed Qubes 4.0 release on fully supported 
hardware. I'd be glad to share whatever cmds outputs you need for 
clarification.

Thanks in advance

Rafael

[qubes-users] Dell Optiplex 7060 Mini - Qubes 4.0.2-rc1

[Peter]

I've installed qubes on a dell desktop that has no PS2 support, and only 
one USB controller.  So it uses a USB keyboard & mouse.  During 
installation I saw no prompt for creating a sys-usb, which I understand is 
the default when you boot with a USB keyboard.

Here is the output of qvm-pci

dom0:00_00.0  Host bridge: Intel Corporation 
dom0:00_02.0  VGA compatible controller: Intel Corporation 
dom0:00_08.0  System peripheral: Intel Corporation Xeon E3-1200 v5/v6 / 
E3-1500 v5 / 6th/7th Gen Core Processor Gaussian Mixture Model  
dom0:00_12.0  Signal processing controller: Intel Corporation 
dom0:00_14.0  USB controller: Intel Corporation   
dom0:00_14.2  RAM memory: Intel Corporation  
dom0:00_14.3  Network controller: Intel Corporation sys-net 
(no-strict-reset=True)
dom0:00_15.0  Unknown: Intel Corporation   
dom0:00_16.0  Communication controller: Intel Corporation  
dom0:00_16.3  Serial controller: Intel Corporation

dom0:00_1f.5  Unknown: Intel Corporation 
dom0:00_1f.6  Ethernet controller: Intel Corporation Ethernet Connection 
(7) I219-LMsys-net (no-strict-reset=True)

I've ready through the USB related documentation, but I'd like to 
understand my usb options better.  

I believe if I try to create a sys-usb for this PC I'll loose my connection 
to keyboard and mouse in dom0 in that case.  Is that correct?

If so, is my only option then to either:

use USB insecurely
don't use USB at all except for the keyboard & mouse attached to dom0

Thanks,

Peter

[qubes-users] Again on vga passthrough

[Strak8]

Every three months for several years I spend a whole day trying to make the 
second video card work on my laptop.
Some will say that it cannot work on laptops for several reasons, in 
particular because the consumer GPU does not support vitualization, because 
on a MUXed system (radeon 7570M) it is impossible to switch two video cards 
simultaneously on the same monitor, almost certainly will not even work on 
the external video output, because the ACPI call fails to load the firmware.
I keep doing so many tests, I find out about dozens and dozens of sites, 
but I only make small steps forward. Now I can load Windows 7 without 
having the blue screen, I see the card in the device manager, but it seems 
to be off. (error code 43).
I put all the options, even though they are probably useless.

rd.qubes.hide_pci=02:00.0 modprobe=xen-pciback.passthrough=1 
xen-pciback.permissive xen-pciback.hide=(02:00.0)

kernelopts  -  iommu=soft swiotlb=16384
gfx_passthru   True  (qvm-features ??)

But I don't understand why:

1. The windows 7 VM with the attached video card loads only with less than 
4GB of RAM (otherwise it is blue screen) 

2. I don't find in any way the possibility to edit the virtual machine 
configuration XML.
   2.1 under "/ var / lib / qubes / appvms / WIN-7-2 /" the configuration 
file no longer exists.
   2.2 I found the way to export the XML with virsh dumpxml, but with the 
qvm-start command there is no longer the "--custom-config" option
   2.3 I force editing the XML from virsh edit (VM) in VIM, but then resume 
the values ​​entered in qvm-features.
   2.4 I can't change the amount of vram? (qvm-feature video-vram?)

3. the Windows guest video drive (both cirrus and vga) there is no monitor 
resolution (1366x768)


Valid and working alternatives:
spice?
ovmf?
dgpu on usb3?
Dell precision 7000 series?

I need windows only because there isn't a valid alternative to photoshop 
and other Adobe products, I don't find myself with gimp and krita.

thanks
bye
