 |
|
Hi
I'm doing a fresh installation and the system boots perfectly, once started, I can use LXDE, enlightenment e17 and fluxbox without problems.
After getting the system to work properly, I started installing Xen, the installation was not specially easy, but not too difficult, so far. Although I had to get bits of information from many sources since none got me a complete bootable system.
My problem is that once I boot into xen, when I run startx, nothing happens, the screen just stays black. I can log with SSH to the system and is not frozen, but no desktop ever appears on screen.
this is the relevant software:
- app-emulation/xen-tools [4.2.1-r3]
- app-emulation/xen [4.2.1-r3]
- x11-base/xorg-server [1.13.4:0/1.13.4]
- sys-boot/grub [2.00-r3:2]
- x11-drivers/ati-drivers [13.1:1]
- sys-kernel/gentoo-sources [3.8.13:3.8.13]
I should also mention that when I boot with the normal kernel, I have framebuffer working fine, but when I boot in Xen, there is no framebuffer, just the old 80x25 resolution.
These are some configuration files and logs
When xen boots xenstored, xend and xenconsoled are started in default runlevel.
Any help to get this working will be most appreciated since I have no clue where to start fixing this situation.
If any more information is required, let me know and I'll post it as soon as I can.
Thanks in advance.
Bye

Hi
No ideas?
Or is it that X just doesn't work on Xen? I thought it did.
Bye

i think this is framebuffer problems.
Many times i try to recompile kernels from 3.6.10 to 3.10.1, whith xen-4.2.2 pae xen hvm support, trying to install xorg-server (whith ati-drivers or nvidia-drivers).
And then i start xorg-server i get blank screen!
And what i get here:
Grub-0.9.7-r12 config:
| Code: |
title Gentoo Linux 3.9.8
root (hd0,5)
kernel /boot/vmlinuz-3.9.8-gentoo-xen-inc real_root=/dev/sda6 root=/dev/sda6 ro
|
xorg-server started whithout problems!
/etc/init.d/xenstored start
* Starting xenstored daemon ...
xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error
FATAL: Failed to open connection to hypervisor: No such file or directory
* Setting domain0 name record
xenstore-write: xs_open: No such file or directory
there is no problem when i try to start xenstored daemon whithout hypervisor prebooted kernel
Grub-0.9.7-r12 Xen config:
| Code: |
title Gentoo Xen 4.2.2
root (hd0,5)
kernel /boot/xen-4.2.2.gz real_root=/dev/sda6
module /boot/vmlinuz-3.9.8-gentoo-xen-inc root=/dev/sda6 ro
|
| Code: | | /etc/init.d/xenstored start |
xenstored started whithout problems!!!!!!!!!!!
BUT!
| Code: | | /etc/init.d/xdm start |
xorg-server shows up the blank screen

i get this every time i try to start xorg-server whith xen hypervisor kernel, but screen every time is blanked!!!!!!!!
so i wait for new kernel release and trying to reinstall xen whith xorg-server from time to time, i didn't get any help in internet.
P.S. I would try to use nouveau driver from modern kernels to make xorg-server work with xen

Try adding nopat to your kernel commandline:
| Code: |
title Gentoo Linux 3.9.8
root (hd0,5)
kernel /boot/vmlinuz-3.9.8-gentoo-xen-inc real_root=/dev/sda6 root=/dev/sda6 ro nopat

This is working boot whithout hypervisor, please read more than 5 strings. (
| Code: |
title Gentoo Xen 4.2.2
root (hd0,5)
kernel /boot/xen-4.2.2.gz real_root=/dev/sda6
module /boot/vmlinuz-3.9.8-gentoo-xen-inc root=/dev/sda6 ro nopat?
|
If you mean boot Xen prebooted kernel whithout pat support? But how it can resolve framebuffer problems?
But thanks for try
I download kernel linux-3.9.11, and compilled it with nouveau support (without nvidia-drivers support)
| Code: | emerge =gentoo-sources-3.9.11
eselect kernel set linux-3.9.11-gentoo
cd /usr/src/linux
make -j3 menuconfig
Device Drivers > Graphics support > Nouveau (nVidia) cards
|
WARNING: gentoo-source-3.9.11 is masked by ~amd64 keyworld
| Code: | nano /etc/portage/make.conf
VIDEO_CARDS="nvidia nouveau"
|
install xf86-drivers-nouveau
| Code: | | emerge xf86-drivers-nouveau |
reinstall messa && x11-drivers whith nouveau support
| Code: |
emerge mesa $(qlist -I -C x11-drivers) -a
|
Edit xorg.conf and set nouveau video driver to use
| Code: |
nano /etc/X11/xorg.conf
Section "Device"
Identifier "Card0"
Driver "nouveau"
BusID "PCI:1:0:0"
EndSection
|
Identifier and BusID can be different on your system.
Then edit your grub menu.lst
| Code: |
nano /boot/grub/menu.lst
title Gentoo Xen 4.2.2
root (hd0,5)
kernel /boot/xen-4.2.2.gz real_root=/dev/sda6
module /boot/vmlinuz-3.9.11-gentoo-xen-nouveau root=/dev/sda6 ro
|
/etc/init.d/xenstored started well
/etc/init.d/xdm started without a problem!!!
In that case proprietary drivers doesn't work well with xen kernels!!!
P.S. If you need to use ati framebufer driver, please let me know i repost howto here
