...g it if xen (the package) and 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...

I have not tried to reboot with the latest kernel-3.10.32-11.el6.centos.alt.x86_64 (if kernel even makes a difference). I *have* had dom0_mem=1024M,max:1024M option in place for all of them with only 6 VM's. Any new suggestions? pjwelsh

...for my environment. I know about memory ballooning (http://wiki.xensource.com/xenwiki/XenBestPractices) and the dom0_mem parameter, but I would like to know what such parameter implies, in practise. Let''s go with my XEN setup now. I have 8GB of RAM and I have seen that if I put dom0_mem=1024M option, the dom0 has 1GB of RAM for itself. What does this really mean? This is confusing me, because I don''t understand how to decide the amount of RAM to assign to the dom0. For example, what if I assign 256M? What if 8192M? For sure you can say to try, but it is not so clear to me what...

...... if there is any other items you want on the 'kernel /xen.gz' line, you would edit the file. For example, I like to add 'com1=115200,8n1 console=com1' to the end of that line so I can use consoles in virsh. So I would change the line: XEN_KERNEL_MBARGS="--mbargs=dom0_mem=1024M,max:1024M loglvl=all guest_loglvl=all" to XEN_KERNEL_MBARGS="--mbargs=dom0_mem=1024M,max:1024M loglvl=all guest_loglvl=all com1=115200,8n1 console=com1" (both of those should be one line if they wrap) This is also where you can assign more or less memory to the dom0. etc. This a...
