Is it possible? How? (looked for documentation, but I didn''t see any.)
I did see xen_cpuperf, but I can''t get any real information from there
either. 8-(
I have 8 domains (including domain-0) runing on the server. If one goes to
100% cpu time, the system bogs. I''d like to be able to ensure that each
instance can''t keep the rest from runing...

By default each domain will get a fair share of the CPU on which it runs -- if N domains are all CPU-bound then each will get 1/N of the CPU. Domains which are woken by an incoming event (eg. network packet or key press) should get run with reasonably low latency. By bogged down, do you mean that interactive response suffers? What is the busy domain doing -- just CPU-intensive work and no I/O? -- Keir ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

Hi Brian, which version of Xen/Xenolinux are you using? the scheduler implementation changed from 1.2 to 1.3-unstable. On Fri, 2004-04-16 at 17:40, Brian Wolfe wrote:> Is it possible? How?

Could you provide a little more detail on what is running in the different domains? In 1.2 the scheduler is a weighted proportional share scheduler (BVT) and by default all domains get the same weight and therefore should get the same share. in 1.3 you have a boot-time choice between schedulers, BVT (same as in 1.2, Atropos (a soft real time scheduler based on EDF) I have just tested with 1.3-unstable, four domains on a dual processor machine (two domains per CPU) and BVT as the scheduler and they happily share the CPU 50/50 if both run the equivalent of a while(1) loop.

Well, I''m not certain exactly to be honest. the filesystems are nfs
mounted. the domain that was eating everything up was stuck in a nasty
php infinite loop.
I''ll see if I can do a bit more tracking and report back. It may very
well
have been a network saturation problem.( gotta locate a few more
compatible cards. and get gig-e backside for the nfs mounts.)
I was also wondering if there is a way to assign a percentage of cpu time
to a domain. Eg guarantee domain 3 gets 25% of the cpu time no matter how
many other domains are in there, or how much cpu time they want.
Also, I assume that xc_dom_control list right most column shows the amount
of time each domain has eaten up?

Xen schedules domains on the available CPUs pre-emptively, so CPU usage limiting should work just fine. The default scheduler (BVT) is configured to provide an equal share of a CPU to each of the domains running on it. You can change the weights so that domains will get larger or smaller shares (there are some options in xc_dom_control.py). A single domain shouldn''t be able to bog down the others on the system by its CPU usage in the default configuration. In fact, the plan is that disk and network usage will also be controllable so that you can give some guarantees on the slice of the machine a domain receives. [I think there are controls in place for network, mechanisms for disk are being worked on] I''ll be checking in a little documentation about the CPU schedulers next week. Eventually, we should have some kind of "friendly" user interface for controlling them. To solve your current problem, a little more information would be handy (e.g. what release you''re using, what scheduler you''re using, anything else that''s odd about the configuration, what configuration the domains have (what is it that is consuming 100% CPU in the domain, are the domains sharing any external resources that could cause performance problems), anything else you can think of).

All network I/O on your system is done via PIO if you''re still using the 3c595 card. Any network-intensive workload will screw system-wide performance. If you care about performance then you need GigE NICs, or a 3c905. -- Keir> Well, I''m not certain exactly to be honest. the filesystems are nfs > mounted. the domain that was eating everything up was stuck in a nasty > php infinite loop. > I''ll see if I can do a bit more tracking and report back.

Sounds great. :) It''s probably that 3com card then that''s
nailing the cpu.
Anyone thought of starting some kind of wiki for xen yet? If not, I''m
willing to toss up some space as xen.terrabox.com and an install of
phpwiki.
I''m definitly looking froward to the new scheduler''s controls.
I''ll wait
as pantiently as I can (heh, bout as good as a kid in a candy store. ;) ).
Thanks guys!
Again, Xen and ya''ll rock!

I think we''d need one that supported logins for editing, and had good revision control. We''ve used wiki''s internally, and they''ve worked quite well for some projects. There''s always the danger that it would be yet another source of incomplete and potentially out of date information. However, perhaps we''d end up declaring the wiki to be the definitive version, and adjusting the READMEs etc just to point at the wiki, or perhaps auto generating them as a snapshot of the wiki. It would certainly be good to pull together Jan''s FAQ, and all the various HOWTOs. As with any kind of documentation, the trick is in having a good editorial team... Have you used MoinMoin wiki? We''ve found this to be the best of the bunch we''ve looked at. It''s a pity sourceforge don''t provide a wiki facility. It''s also a shame that their mailing list archive isn''t as good as the gmane.org one...

How about a 3 part wiki then?
part I = Stable xen docs (by coders and approved volunteers.)
Part II = Unstable Xen docs (more informal like the readme''s and
current
docs.)
Part III = User contributed docs. (Q&A for end-users, faqs, specific
howtos etc.)
As I said, I would be glad to host a site for it. :) I have a partial one
setup for my xen virtual server account users at http://wiki.terrabox.com.
Maybe I should just go ahead and set one up....

OK, the scheduler-related updates I mentioned have been pushed now. There''s some (brief!) scheduler documentation in docs/Sched-HOWTO.txt and xc_dom_control.py can now set parameters for Atropos and Round-robin, as well as BVT. The scheduler control interface is rather "raw" at the moment. At some stage we''re planning some friendlier controls for the scheduler so it''ll get easier to use and harder to shoot yourself in the foot ;-) If you have any problems, yell!

Addition to my message: I copied from hda5 to hda8 the relevant directories using cp -pr (bin boot dev etc initrd lib home opt sbin tmp var), couldn''t copy proc (is it created and populated at boot time?).

does dom0 still have /dev/hda8 mounted? unmount it. how does dom0 have /dev/hda6 mounted? if it is mounted read/write, mount it read-only. for all partitions: If you want to mount a partition rw in one domain it *can not* be mounted in any other domain If you want to mount a partition in multiple domains it has to mounted *read-only* in *all* domains.

I have the partitions for separate / and /usr for domain-1 but no luck with domain-1 boot success. Domain-0 error about sharing partitons across domians is gone though. So, I would like to know how does exactly domain-1 boots(or will) based on the info in it''s / partition or domain-0 / partiotion. 1. Does it use the /boot/grub info of either dom0 or dom1? 2. Does it use the /etc/fstab entries of dom0 or dom1? Any other ideas involved that might significant here? -ishwar On Tue, 20 Apr 2004, I RATTAN wrote:> I am back to trying xen-1.2 and need a little(?) help. > > Hard disk config: > hda1 (primary swap), hda2(extended): had5(/, 1Gb), hda6(/usr, 2Gb), > hda7(1Gb), hda8(1Gb) > > Installed Fedora-core-1 using / and /usr > Downloaded precompiled xen-1.2-install.tar.gz > Installed it > Able to boot domain-0 > > How do I put root partition info for dom1 on partition hda8 > I tried dd if=/dev/hda5 of=/dev/hda8 bs=1024 > aborts with I/O error after copying the file system > (mount says that it is invalid FS etc..) > > Is there another way?
