similar to: How to get actual DOMU scheduling parameters ?

This patch -Displays[1] current parameters for running domains ala xm list -Allow users to set[2] one or more parameters[3] without having to provide values for parameters they do not wish to change -Adds additional testing of sched-sedf via new xm-test testcases. With this patch applied, test 02_sedf_period_lower_neg.py exposes a bug[4]. I''ll follow up this email with a patch for

9d1fd58ff602 was bogous in not letting a new domain being created if its scheduling parameters --when running under the sedf scheduler-- were not fully specified, making creation fail like in this example here below: 2012-06-16 07:37:47 Z executing ssh ... root@10.80.248.105 xl create /etc/xen/debian.guest.osstest.cfg libxl: error: libxl.c:3619:sched_sedf_domain_set: setting domain sched sedf:

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/

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, I''ve installed xen-unstable 4.2 from actual git (last commit was 4dc7dbef5400f0608321d579aebb57f933e8f707). When I start a domU with xm all is fine include the cpu_weight I configured in my domU config. When I start the domU with xl then all my domU have the default cpu_weight of 256 instead of the configured one. Was the name of cpu_weight being changed for xl command ? My domU

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 <

Here are some patches I compiled to get sedf_get to the XendClient API... sadly, however, the current xc frontend is missing a variable (weight) and needed to be edited. Below are my "homemade" patches (I did this since my code base is EXTREMELY old... however the code is still valid) tools/python/xen/lowlevel/xc/xc.c line 766 static PyObject *pyxc_sedf_domain_get(PyObject *self,

On a 8 Core system only dom0 can set cap > 100 and vcpus > 1. On a domU ''xm sched-credit -d <domU> -c 200'' says "Error: cap is out of range". Vcpu cannot be set higher than 1 - regardless of boot/config/command line. Low performance is equivalent to the cap setting. See ''xm list --long'': (domain (domid 0) (uuid

Dear list, as my Xen3 server is finaly becomming ready for production I was wondering if anyone has written a xen usage monitoring/logging tool? Something like xm top, but with continuose logging to a (rr)database. Or a munin plugin? I can''t remember seeing anything simmilar on the list. BTW: where does xm top get the NETTX(k) and NETRX(k) from? For a munin plugin I''d

Hello, Is there a way from within a DomU to obtain the hostname of the associated Dom0 ? We need this because we want to know at every moment on which host the DomU is located Regards Pierre _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, Can someone clarify for me the numbers that show up in Xenmon? Specifically, I''m curious about the "domain31" entry which always shows up. It looks like this represents the free resources. Also, does anyone know what would happen if more than 30 domain0''s were started (or more likely, I did enough migrations to raise the next domain ID to above 30)? Thanks for

Hello, I''ve been trying to get xenmon.py and xentrace to work, but I consistently get the following (on a couple of different machines/kernels): kibab kibab # xentrace /root/xentrace.log ERROR: Failure to get trace buffer pointer from Xen (22 = Invalid argument) Did I miss an option that has to be turned on or something? Is there some other setting that I need so that everything

Hello, I have a question about the way Xentrace takes a trace. In previous versions of Xen, I took a trace by setting the size of buffers, activating them and writing the information into a file (optional). setsize 20 tbctl 1 xentrace /tmp/xentrace.dat Now I''m using xen-unstable and I see that setsize is already integrated in xentrace command. My question is: does start/stop buffer is

good morning, We belong to PSA Peugeot Citroen Company and we need to install SAMBA on OS AIX5.3 with LDAP access. We download the SAMBA binaries 3.0.21 but in this version, we could not find the libraries for LDAP ACCESS. Could you tell us , if we have to download another version or where we can find the library for version 3.0.21. Further more , do you know if we can find a french company

Please CC as I''m not subscribed to valgrind-developers. Under Xen the toolstack is responsible for managing the domains in the system, e.g. creating, destroying, and otherwise manipulating them. To do this it uses a number of ioctls on the /proc/xen/privcmd device. Most of these (the MMAPBATCH ones) simply set things up such that a subsequenct mmap call will map the desired guest

I am seeing a problem with Dom0 crashing on x86_64 whenever I create a DomU. I''ve done some more testing, and it appears that this problem is somehow related to networking. Dom0 crashes as soon as the networking services are started when DomU is coming up. As an experiment, I brought up DomU without networking, and it stayed up. As soon as I started DomU with networking enabled, however,

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

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
