Hello I''m in trouble using the bvt scheduler with the command line. the command "xm sched-bvt help" explain that it need 6 argument but that''s all. I have read a previous conversation for bvt example with command line, but it doesn''t work I try (5 is the id of the concerned

Hi, I''m trying to create a new gallery layout. I did the following: o create plugin/foobar.rb in my base directory. o copy plugins/gallerylayouters/default.rb in foobar.rb and make appropriate modifications. For simplicity, lets say my class looks thus: require ''webgen/plugins/gallerylayouters/default'' module GalleryLayouters class Foobar <

Hi everyone, I''m running Xen on an SMP machine. Couple of things: a) is dom0 pinned to a particular CPU? if so which? can I control the choice? b) with the 2.6.10 Xenolinux kernel, cat /proc/cpuinfo shows only a single CPU on my SMP machine. Is this a known problem/behavior? c) if I understand correctly, the BVT scheduler parameters are CPU specific -- they don''t aggregate

hi all, im am trying to allocate cpu to the various domains using a bvt scheduler. so now lets say i want to give the first virtual machine a weight of 1 and the second a weight of 2. this should result in domain1 using 33% of the cpu and domain2 66%. however since xm sched-bvt takes inverse of the weights as input so i do 1/1 and 1/2 and hence do "xm sched-bvt vm1 2 0 0 0 0" for the

Hi folks BVT and EDF are both xen scheduler. It is expected that administrator will choose the scheduler most appropriate to their application and configure the machine to boot with that scheduler. I just wonder What''s the main difference between BVT and EDF? What kind of scenario to use them? Thanks _______________________________________________ Xen-tools mailing list

Are there any examples of bvt scheduler parameters usage? If I understand it right, bvt provides me with option to scale domain''s CPU usage. Eg. I have 2 (non-zero) domains pinned to the same CPU. Can I assign eg. 30% of CPU time to domain 1 and 70% to domain 2? (I mean in peaks when both domains are not idle and require the CPU time) If yes, how should I build the "xm bvt"

Hi everyone, I''m trying to convert some Xen HVM images to run on VMware ESX, unsuccessfully thus far. I believe the problem is that ESX by default wants the VMs to use SCSI virtual disks, but my HVM VMs are configured to use IDE virtual disks. If you have any experience with this sort of thing, please get in touch. Thanks! Diwaker -- http://floatingsun.net/

Cycling around many CPUs in XenMon''s curses mode can get cumbersome. This trivial patch adds bindings to move to the previous CPU. The next/previous binding seems more natural to me than the earlier cycle binding, but we can keep them all for now. # HG changeset patch # Node ID 146b5c76086c07fad61bea7ccf60f2f4fd66abbd # Parent 7dd31dbf16e75f0f70e0f9c44b2bb2b5fc6eecf1 Add next/previous

Hi everyone, I''ve created a new Wiki page [1] to document my understanding of the credit scheduler as I try to figure out the code. Please feel free to add/correct!

Hi, I have a naive question with the xen BVT scheduler. Supposing I have only one guest domain runnning on domain 0 and with the xm bvt command I have allocated cpu units in the ratio 9:1 to domain 0 and domain 1(say) respectively. Now I create another guest domain. How much CPU share it (or subsequent domains created after it) will get? ~$ubh _______________________________________________

I''m trying to understand interrupt handling in Xen (as described in the "Restructuring I/O" techreport). But I''m having a hard time finding all the bits and pieces in the code. For instance, the text says "a device''s interrupt line triggers execution of a stub routing within Xen rather than causing immediate entry into the domain that is managing that

I''m using a tree forked from xen-unstable in mid-July, with debug mode on. With long testing runs in a domU in a multiprocessor host, I get the above assertion maybe one in five times. There was a message from early June saying that the invariants had changed, and that the ASSERT() in question was no longer right, but it''s still in xen-3.0-testing. Can anyone verify that the

Attached is the second release of XenMon, which is a unique performance monitoring tool for Xen. Instead of using hypervisor calls to get domain information, we use the xentrace facility to provide fine-grained monitoring of various metrics (see README below). We have written up a small case study that demonstrates the usefulness of the tool and the metrics that it reports. This will be

Hi list, I''m using xen 3.0.0 and wonder how to obtain the 6 DOMU scheduling parameters from my DOM0 domain. Sort opposite of the sched-sedf xm sub-command Can someone help me ?

Hi folks, I''m trying to use the atropos scheduler with Xen. Couple of questions: - the scheduling param *has* to be specified at boot time right, or does Xen allow changing the scheduling scheme at run time?? - xm help atropos gives a very vague message at best, perhaps we could make it more elaborate: xm atropos DOM SLICE PERIOD LATENCY XTRATIME o is DOM the vm ID or the vm NAME (as

Hi, I read about RPC interface for xenmon in this presentation: www.xensource.com/files/xs0106_xenmon_brief.pdf Has such interface been implemented yet by anyone?

Hi everyone, This is for Xen 2.0.3. I''m really interested in the functionality of atropos (enforcing CPU partitioning in a non work-conserving fashion). As I had reported earlier, atropos seemed broken in 2.0. It still seems broken now: $ xm list Name Id Mem(MB) CPU State Time(s) Console Domain-0 0 123 0 r---- 49.1 vm1 1 47

Currently with the credit scheduler, cpu_weight cannot be assigned to guest domains at boot time.(it can be set with xm sched-weight after booting) This patch allows CPU weight, and CAP to be set by the Xen configuration files. Specification: The following can be added to the Xen configuration files. 1.CPU WEIGHT [OPTIONAL] cpu_weight = cpu weight value -sets the cpu time ratio to be

Hi everyone, I''m doing some networking experiments over high BDP topologies. Right now the configuration is quite simple -- two Xen boxes connected via a dummynet router. The dummynet router is set to limit bandwidth to 500Mbps and simulate an RTT of 80ms. I''m using the following sysctl values: net.ipv4.tcp_rmem = 4096 87380 4194304 net.ipv4.tcp_wmem = 4096
