Added a new ethernet card.  Added “pci=nomsi” to get it working.  Otherwise, it 
was not getting interrupts.

Thanks for that.

I have a USB2 controller in one of my machines that behaves similarly. Try
putting the problem device in a "sys-net2" and experimenting with adding
kernelopts like "pci=nomsi" or "irqpoll".

Check /var/log/Xorg.* logs to make sure it's not software rendering.

[qubes-users] HP Z8 G4

[Damon Permezel]

Sort of a progress report.  I will eventually try and put together something 
more meaningful for the HCL.

HP Z8 G4
Dual “Intel Silver 4114”, hyperthreading disabled.
64GB memory.
nVidia.
PS3 style keyboard and mouse.

Storage still sucks.  Currently running off an enterprise NAS 4T drive on a SAS 
controller.  Will migrate to NVMe/PCIe3 and SSD.

Mellanox 10G dual adapter.
“native” dual 1G ethernet:
  i219-LM
  X722

With the correct BIOS options set to enable all the requisite hypervisor 
functions, installs and boots.
Install failed once due to a Fedora anaconda hang problem, but then succeeded.

sys-net initially failed, due to one of the two 1G ethernet devices not having 
FLR or bus reset, but there is an option in the template editor to not require 
that.

Still, that device, the X722 one using the i40e driver, is useless for 
networking as the TX interrupt never fires, and the driver times out and resets.

The other ethernet port, which uses the e1000e driver, works.

I assume the 10G will work, but have yet to try.  That will (eventually) give 
me access to the different VLANs I have.

The system for the brief time I have used it seems really sluggish, but I am 
sure that is the slow NAS drive: 5400RPM.  Not sure if 3G or 6G connection.
GUI seems sluggish as well, though, even though `top` shows pretty much 100% 
idle.

The box has a TPM.  IIRC, I asked for a 2.0 TPM.  No time yet to do the AEM 
stuff.

The above happens after the first stage of installation completes and it
reboots.

Found this one too, reported as happening on 1/5 installs:
https://bugzilla.redhat.com/show_bug.cgi?id=1468896

Try again, and check anaconda.log for errors I guess?

[qubes-users] HP Z8 G4 4.0 install

[Damon Permezel]

Fixed the BIOS issues.  Now no warnings re missing features.

Now, however, I am stuck on “Preparing transaction from installation source”.

It did not ask me about whonix or about usb.  Just skipped to install.

I find that there are some old closed bugs reported against fedora re the 
“Preparing …” issue.

[qubes-users] HP Z8 G4 issues

[Damon Permezel]

The dual “silver xeon 4114” CPUs in my spiffy new HP Z8 claim support for:

   vPro, HT, VT-x, VT-d, VT-x with EPT.

On install of 4.0, I am presented with a list of missing features:

HVM/VT-x/AMD-v, IOMMU/VT-d/AMD-Vi, HAP/SLAT/EPT/RVI, Interrupt Remapping

Interrupt remapping is part of VT-d.

I guess these are turned off in the BIOS and as the BIOS will not let me turn 
them on, I am hosed.

Damn.  I specced this machine specifically to run Qubes, and was prepared to do 
some level or dorking about to get it to work, but did not consider that 
someone would lock out features in the BIOS.

However, having said that, when I boot up some linux on it, lscpu tells me that 
at least some of these are enabled.
