Hi List,

I have some problems with enabling VGA_PASSTHROUGH in XCP. I enabled vga 
passthrough and I can see the pci nvida qudro 2000 card in the quest vm. At the
moment it is visable as secondary video card and the emulated Cirrus Logic card 
is the primary video card. According to the 
document, I should also set the "gfx_passthru=1"  in the /etc/xen/<guest> 
cfgfile in order for the nvidia card to become the primary video card. But how 
can I set
this parameter if I am using XCP? no guest gfc file exists but is somewhere 
else in the XCP environment/database??? accessible via xe commands??? setting 
of the
other-config parameter of the vm?? platform parameter??
