Tips for Linux in HVM domain
|
|
============================
|
|
|
|
How to fix bootup kernel error
|
|
-------------------------------
|
|
|
|
If the HVM pauses on boot and shows a series of warnings, visit [HVM Troubleshooting](https://www.qubes-os.org/doc/hvm-troubleshooting/#hvm-pauses-on-boot-followed-by-kernel-error) for a fix.
|
|
|
|
Screen resolution
|
|
-----------------
|
|
|
|
Some kernel/Xorg combinations use only 640x480 in HVM, which is quite small.
|
|
To enable maximum resolution, some changes in the Xorg configuration are needed:
|
|
1. Force "vesa" video driver
|
|
2. Provide wide horizontal synchronization range
|
|
|
|
To achieve it (all commands to be run as root):
|
|
|
|
1. Generate XOrg configuration (if you don't have it):
|
|
~~~
|
|
X -configure :1 && mv ~/xorg.conf.new /etc/X11/xorg.conf
|
|
~~~
|
|
|
|
1. Add HorizSync line to Monitor section, it should look something like:
|
|
~~~
|
|
Section "Monitor"
|
|
Identifier "Monitor0"
|
|
VendorName "Monitor Vendor"
|
|
ModelName "Monitor Model"
|
|
HorizSync 30.0 - 60.0
|
|
EndSection
|
|
~~~
|
|
|
|
1. Change driver to "vesa" in Device section:
|
|
~~~
|
|
Section "Device"
|
|
# (...)
|
|
Identifier "Card0"
|
|
Driver "vesa"
|
|
VendorName "Technical Corp."
|
|
BoardName "Unknown Board"
|
|
BusID "PCI:0:2:0"
|
|
EndSection
|
|
~~~
|
|
|
|
Now you should get resolution of at least 1280x1024 and should be able to choose other modes.

Qubes agents
|
|
------------
|
|
|
|
Linux Qubes agents are written primarily for PV qubes, but it is possible to run them also in a HVM qube.
|
|
However some work may be required to achieve this. Check [this thread](https://groups.google.com/group/qubes-devel/browse_thread/thread/081df4a43e49e7a5).
