Hi,
I was able to follow the instruction on
http://wiki.xenproject.org/wiki/Install_Xen_4.2.1_with_Remus_and_DRBD_on_Ubuntu_12.10
to get a working Remus with PV guests.
But now I am trying to do the same thing but for HVM guests. So I created a
HVM guest on Xen by following https://help.ubuntu.co
Hi Changlong,
Are you suggesting I should hold off on setting up COLO for now?
Thanks!

Thanks for the reply!
So I am trying to follow your new instructions, but when I am trying to do
this:
cd ~/colo-proxy/; git checkout 405527cbfa9f
I got the following error:
"error: pathspec '405527cbfa9f' did not match any file(s) known to git."
I assume it is just a typo? Tha
Hi,
I am trying to set up COLO by following this
http://wiki.xenproject.org/wiki/COLO_-_Coarse_Grain_Lock_Stepping
I was able to follow the step up to

When I try to run the above command, I got the following error:

Hi all,
A little update,
so yea when I run with tasks that has utilization less than 0.5. Xen-RTDS

Thank you guys very much for helping me understand the problem!

y.
I am hoping to see that the VM1 using xen-rtds will perform better than the
VM1 using xen-credit, but what I am seeing is the opposite.
Thank you!

At this point I think the best way is to install the newest litmus-rt
(litmus-rt-2015.1.patch)
?
Again, thank you very much, I really appreciate your help!

Hi all,
So I was doing some experiments to evaluate RTDS scheduler schedubility of
real time tasks using 1vm with period of 1 and budget of 1. The
experiment results turn out as expected(perform better than xen-credit).
But when I tried to perform similar experiments with 2 vms (both with
767? I never created
those domains and they took up most of the dump-all file.
Again thank you very much for your reply. and sorry for the long replies
if my reply format is wrong, I am new to mailing list too.
