Re: [qubes-users] Q 4.0 updates took my sys-net off line

2018-05-07 Thread Coleman, Steve L.
I am still offline since that faitful dom0 update/reboot for whatever reason, 
but have been unable to find the time to resolve this, due mostly to being 
off-line. I got a few minutes before work today to try a few things, without 
any luck. I switched back to hvm mode since pv didn't buy me anything. Trying 
random things is obviously not the best methodology.


I had noticed that qvm-prefs was displaying network information (IP address) 
that the qube-manager did not. But I would not think that the gateway should be 
equal to its own IP address though. I just wish I had a working system so I 
could compare configurations.  After playing with qvm-prefs --set the 
qube-manager seems to at least be finally displaying the same information. Not 
that it helped anything.

The nic interface name also seems to have changed, again. It used to be eth0 
back when everything was working, before that dom0 update, then the IF was 
missing entirely,  then it first showed up as enp0s0, and now showing up as 
"ens5", but there is still no dhcp happening on that interface to obtain an IP 
address from the real network.


Q: What property/action in dom0 is supposed to cause this dhcp to happen in 
sys-net?

Q: Why would the if name be changing like this? Is it a HVM vs PV interface 
driver convention? If so, what causes it to change to eth0 which used to work?


thanks,


Steve

Subject: Re: [qubes-users] Q 4.0 updates took my sys-net off line

Have you tried using a different template to generate sys-net?

Yes, I have tried my fedora-26-net, fedora-26-minimal, and generic fedora-26 
templates with both the old sys-net and the one I re-created.  None of that 
helped.



It is always Fedora, perhaps Debian...

The thing is that the updates were patches on the Dom0 side of the world that 
broke it. The template used by sys-net was not even changed and fedora should 
just work, as it is the default for the Qubes system.

At first the enp0s0 interface did not appear in sys-net at all, and I have been 
struggling to try to bring the if up, and nothing I have tried so far seems to 
work.  I managed to get the network card assigned to sys-net but I don't know 
what dom0 invokes within sys-net to tell it to do the dhcp stuff.

[qubes-users] Q 4.0 updates took my sys-net off line

2018-05-02 Thread Coleman, Steve L.
Yesterday I pulled some Dom0 updates and rebooted to complete the install, and 
since then had no luck at getting it back online. My sys-net is not properly 
configuring the network card so that eth0 never gets configured properly and 
assigned an address.


I have tried switching between HVM/PV modes with no luck. I created a new 
sys-net and assigned the controller over with no joy either. Any advice on what 
to look at next would be very much appreciated.
