Re: Is Xen VGA Passthrough to CentOS 6.3 x86-64 HVM domU successful?

["Teo En Ming (Zhang Enming)" <singapore.mr.teo.en.ming@gmail.com>]

My CentOS 6.3 x86-64 HVM domU configuration:

# This configuration file will only work with Xen 4.1.3-rc1-pre and NOT
# Xen 4.2-unstable due to the disk parameter.
#
# XL domain configuration file for Ubuntu 12.04 Precise Pangolin Beta 1 
amd64 HVM domU
# Please refer to "man xl.cfg" for further explanations.
