[Xen-users] Urgent: How to evaluate Xen migration performance??
Hello all, I am running Xen 3.0 on two physical machines with Centos 5.2 installations. I need to evaluate the performance of Xen with respect to total migration time, downtime, sizes of VMs, CPU usage and its effect on other applications running on the VMs. Is there an in-built mechanism to judge these parameters? How do I go about making these measurements? I have a presentation tomorrow about the same, and would be grateful for any help on the matter. Thanks & Regards, Siddharth Wagh ---------------------------------------------------------------------------------------------------------------------------------------------------------- Many of life''s failures are people who did not realize how close they were to success when they gave up... ---------------------------------------------------------------------------------------------------------------------------------------------------------- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Geez man, Talk about cutting it a bit close. You sound like a client who wants the magic "render button" next to the any key. Take a week and do some research, the traditional Unix tools will give you the info you need. In my tests, the Xen migration took just a few minutes but this is of course using shared storage of some kind. - Brian On Mar 4, 2009, at 3:55 PM, Siddharth Wagh wrote:> Hello all, > > I am running Xen 3.0 on two physical machines with Centos 5.2 > installations.

It looks like xentop can help me out here. But when I try it out, it gives me the following error: OSError: [Errno 2] No such file and directory Thanks & Regards, Siddharth Wagh ---------------------------------------------------------------------------------------------------------------------------------------------------------- Many of life''s failures are people who did not realize how close they were to success when they gave up... ---------------------------------------------------------------------------------------------------------------------------------------------------------- On Wed, Mar 4, 2009 at 7:04 PM, Brian Krusic <brian@krusic.com> wrote:> Geez man, > > Talk about cutting it a bit close. > > You sound like a client who wants the magic "render button" next to the any > key. > > Take a week and do some research, the traditional Unix tools will give you > the info you need. > > In my tests, the Xen migration took just a few minutes but this is of > course using shared storage of some kind. > > - Brian- Show quoted text - > > > > > > On Mar 4, 2009, at 3:55 PM, Siddharth Wagh wrote: > > - Show quoted text - >> Hello all, >> >> I am running Xen 3.0 on two physical machines with Centos 5.2 >> installations.

Great, I got working. "xm top" gives errors (something developers should look into?) "/usr/sbin/xentop" does. I will record the data in some file and get the graphs done. Sorry to spam you guys, but I am new to this and as you can see, under a lot of stress!
