...nd the xen kernel are installed. But only if the user WANTS to run it. 2. Allow users to automatically modify the variables passed into the xen.gz line (that is, more or less memory, add console settings, etc.) If you look at the current script, "--mbargs=dom0_mem=1024M,max:1024M loglvl=all guest_loglvl=all" is hard coded in as the only option for the xen.gz line. While doing that we also still want to preserve the ability to run that kernel in other places than just for xen dom0 setups. Here is how I propose we do that. Currently the /usr/bin/grub-bootxen.sh file is in centos-release-xen...

Dear mailinglist, I own a Gigabyte motherboard GA 970A UD3 with IOMMU support. Since the update XSA-36 (also part of the latest debian wheezy pkg), the IO-Virtualisation does not work any more as discussed on this mailinglist [0] and [1]. I like to ask, if there is an "official" solution in sight. I''m not sure about my alternatives. How "dangerous" is the
