4) The ln -s has the arguments reversed which ends up leading to the docker 
install storage in /dev/xvda3 (/var/lib/docker) instead of in /dev/xvdb 
(/home/user/var_lib_docker), so it fails on my system as / runs out of room. 
I've reversed the arguments in the ln -s and it is working now.

Thanks a bunch!

As ever, it's a trade off. Performance will be affected to some extent -
whether you will actually notice depends on the other hardware.

The document says:
# of Cores = 4
# of Threads = 8

So...four cores. Qubes disables hyperthreading (allows a core to appear as two 
virtual cores) due to security issues with hyperthreading.

You almost certainly dont have 8 cores - you probably have a 4 core CPU
with hyperthreading.
By default Qubes disables hyperthreading for security reasons.

To solve it, it would be helpful to get some more information:
- what modell is the CPU?
- which Qubes version are using?
- are you looking into the AppVM or into the Hypervisor

Please post the output of:
cat /proc/cpuinfo
xl vcpu-list

Could it be that you mix up the total cores yout system have, against what
you can see in an AppVM?
AFAIK dom0 is also just an AppVM on top of Xen and therefore you might see
only the cores which are assigned to dom0?
The xl commands should help you.

Thank you for the informative reply. I have since learned that gaming on one PC 
while streaming from another is a thing.  There are even PC cases made to house 
two separate motherboards, power supplies, etc for this purpose.  I still don’t 
understand why anyone would want to do this, gamers have been streaming just 
fine from their gaming rigs for years. I suppose a dual system could be useful 
against ddos and other attacks.

[qubes-users] Icons on my desktop security question?

2019-04-18 Thread 22rip
Rookie question:

1) Why I didn't discover this before I don't know, simply drag the program from 
the Qubes drop down menu onto the desktop i.e. drag "Fedora-dvm-Firefox" or any 
other app program onto the desktop for easy access.

Does this impact my Qubes security? It asked if I want to execute this program 
the first time I use the icon, clicked "Yes"...

Pretty slick feature...

[qubes-users] Disk Decryption on system Startup

2019-04-18 Thread luserx0
Greetings,

On the SSD storage cache thread there is a clear comment on the support for 
multiple encrypted disk unlocking on Qubes startup.

Running two disks each containing a different pool I have some problems when I 
am prompted for my decryption password. Problem is there is no identifying of 
which device I am unlocking and if I'm too late on the second device password 
or provide the wrong passphrase I better reset.

A potential walk-around would be to set the same password on both devices, but 
it's obviously not the best idea.

Is there a way for Qubes (or Xen?) to identify which device is being unlocked 
and load it upon decryption prompt?

Hiya 799,

Thanks for this effort.

1) I had to remove the "-" from a variable assignment/use: "MirageFW-BuildVM"  
"MirageFWBuildVM".

2) An error was returned after soft linking to the docker directory before it 
was created (which happens in a later command), but that was not a blocker to 
continue.

3) The build is failing due to missing components in the build script, so I am 
stuck there, see below:

Running the build script, I get this output:

Re: [qubes-users] randomizing VPN servers i connect to with my vpnvm?

I was thinking the line "remote random" in my .ovpn file, along with the

that doesnt *seem* to be the case, the bit that was included in the

remote-random
resolv-retry infinite
nobind
cipher AES-256-CBC
auth SHA512
comp-lzo

Is there something else i need to do? I assumed it would either change 
when it reconnects or is restarted but that doesnt seem to be the case.




You also have to specify multiple "remote" lines, one for each address.

[qubes-users] Windows 10 Pro HVM does not work with Mirage Firewall

2019-04-18 Thread Claudio Chinicz

Hi All,

Once again I turn to the Qubes Community to ask for help.

I have a Mirage Firewall VM that works with HVM (Linux Mint) and 
Debian/Fedora template-based PVMs.


My Windows 10 HVM, which works just fine through sys-firewall 
(copy/paste and file sharing with other VMs dont, but I can live with it).


I've tried setting up networking manually by adding its IP, mask and 
gateway and rebooting but it did not work. It works with DHCP instead 
when getting network through sys-firewall.


I've followed all the ideas from here 
(https://www.windowscentral.com/how-regain-internet-access-after-installing-update-windows-10) 
and it still did not work.


One last piece of information, my Windows 10 Pro was successfully 
activated using a key I provided.


Any ideas? This is not critical, since I can continue using 
sys-firewall, but would love to free some memory by using Mirage.


Thank you all in advance,

Claudio

Re: [qubes-users] Spontaneous rebooting

Is it possible that you are suffering from over-heating? That would
account for symptoms.


I'm now monitoring temperatures with the "sensors" command in a dom0
terminal and although the problem hasn't yet happened again, the
temperatures I'm seeing are often getting close to or even reaching
"Critical":

coretemp-isa-
Adapter: ISA adapter
Package id 0: +100.0°C  (high = +84.0°C, crit = +100.0°C)
Core 0:    +99.0°C  (high = +84.0°C, crit = +100.0°C)
Core 1:   +100.0°C  (high = +84.0°C, crit = +100.0°C)

acpitz-virtual-0
Adapter: Virtual device
temp1:    +99.0°C  (crit = +200.0°C)

thinkpad-isa-
Adapter: ISA adapter
fan1:    4788 RPM

If over-heating is the cause, does that suggest a hardware problem, or
is there something I can do to configure Qubes differently to stop it
from getting so hot?



That's not good. Usually CPUs shut down and cause a reboot as you 
observed at 100-110 Celsius (CPUs may die at higher temperatures and 
thus perform an emergency shutdown).


Looks like you have a hardware issue with your CPU fan. Either cleaning 
the CPU fan and replacing the thermal paste or replacing the entire CPU 
fan is likely to solve your issue. Youtube videos are your best friend 
there.


I had similar syptoms in the past, replaced the fan and thermal paste 
(apparently the seller had applied way too much) and went down to 70-80 
Celsius at maximum load.

Hi All,

I'm trying to install/test/play with Mirage, following
instructions from
https://github.com/mirage/qubes-mirage-firewall.

Honestly, I've got entirely lost, since I'm not a pro and not
proficient
with Linux.

Can anyone provide a step-by-step recipe how to install the unikernel?


I was also struggling with the installation, therefore (and to save 
time for the Mirage Pros to develop the firewall not helping newbies 
like myself) I have created a howto:


https://github.com/Qubes-Community/Contents/blob/master/docs/customization/mirage-firewall.md

You can run all steps from dom0 ;-)
If you need further help, to not hesitate to ask.
I'd like to hear your feedback, if we can improve the howto.
