Thanks for the guide powerhouse!
I have a problem at step 15 as well. I'm using linux mint 17 and two 290x gpus. I followed the guide except that I used the x1 toolstack and added: device_model_version = 'qemu-xen-traditional'....I also skipped steps 9 and 10 for now. I can boot into xen once, but after that it black screens once I enter my password and login. I still see and can move the mouse cursor, but no desktop. I could also use "ctrl alt f1" to get to a cli login.
I tried using this: viewtopic.php?f=47&t=163317#p843200
, installing fglrx drivers both by command line and by installing directly from the amd website, but got the same thing only now I could no longer use "ctrl alt f1" to get a cli. I would just get a black screen instead of prompt. I tried booting into the linux mint kernel and got the same behavior at the login screen as xen, but was able to access a cli.
From there I tried using the grub options:
GRUB_CMDLINE_LINUX_DEFAULT="radeon.blacklist=1 quiet splash nomodeset"
GRUB_CMDLINE_LINUX_DEFAULT="radeon.blacklist=1 radeon.modeset=0 rd.driver.blacklist=radeon rd.blacklist=radeon quiet splash"
no change except for the boot screen looked different.
I tried pulling out the second gpu, but that didn't help either. It's weird that the normal kernel gui no longer works after booting the xen kernel.
You mentioned this:
"However, if you choose to use 2 AMD or 2 Nvidia graphics cards, you would need the respective driver for your dom0. In that case the PCI devices should be detached before the driver starts. You may need to run update-rc.d pciback defaults 21 19 with different numbers, or find another way to run this script before the graphics drivers are loaded."
Does anyone know a time when the pciback script can be run?
Is there anything else that I can try? Thanks for the help!
