[Libvir] The problem of the definition of tuning informations
by Daniel Veillard 15 Nov '07

15 Nov '07

I promised that mail for the beginning of the week but I still have a very hard time to try to formulate a good plan of action, I'm still stuck in a dilemna, see below. What is it? ----------- I think tuning informations are that set of parameters associated to a domain or a host, which are not stricly needed to get the domain(s) working but improve their runtime behaviour. To me this includes: - scheduling parameters the scope may be host/hypervisor/domain - vcpu affinity i.e. to which set of physical CPU each of the vcpu may be bound - and possibly others ... The problem: ------------ People would like to associate those to the XML domain informations, the goal being to be able to restore those informations when a domain (re-)starts. I have been objecting it so far because, I think those informations don't have the same lifetime and scope as the other domain informations saved in the XML. Since they are not needed to start the domain, and that once the domain is started the existing domain API can be used to change those informations, it is better to keep them separate. However I got objections from David Lutterkort [1], Jim Fehlig [2], and John Levon [3] plus of course the initial request for it from Tatsuro Enokura (and the Fujistu people in general) [4] The problem to me comes from 2 things: 1/ storing tuning informations in domains descriptions is not sufficient 2/ if we store them there we also need to always save them when exporting the XML domain file 2/ is fairly important to avoid a lot of problems as we have experienced before for example with console informations. If the input for virsh create gets different from the output of dumpxml, a lot of rather annoying things happen in practice, it certainly generate confusion. So we really need to output those tuning data if we put them in. Also I strongly believe in 1/, i.e. tuning informations are cross domain and they are vey likely to change fast as soon as the management applications will get deployed, but even in relatively small deployment the tuning is rather a per host informations, which may depend on the current workload of the machine. I don't believe in tuning being loaded at create time and never changing later. Even in my own very basic usage that doesn't match my use which lead me to load and stop domain on demand for short period of time. My opinion: ----------- We need better tools, even for simple use case to be able to save an existing tuning for a domain or a full machine, and reload it when needed. This is IMHO better done on top of the existing API which already have the entry points to implement them. My idea is to provide tuning commands in virsh [5]. If you implement tuning both at creation time and in the tool, this mean you either make them different in which case you have no coherency between what you say when you create a domain or save its config and what you do at the virsh level. If you don't make it different (for example trying to use the same kind of XML syntax), then you need code for doing this both in the tool and in the library itself, or you export as a new API the tuning load and save. Exporting as a parallel API what we have already for scheduling and VCPU affinity makes the API more complex, and less coherent. I don't want to force the decision one way or another, it is probable I missed something, but I don't think adding tuning informations to the domain configuration file to be really that convenient, I could be done better, and with less associated problems by keeping those separate.

[Libvir] latest NUMA/cpuset code testing
by beth kon 15 Nov '07

15 Nov '07

I tested the latest CVS libvirt on a 128-way x3950 and create, define, and start appear to work well with various cpusets specified. The only thing I noticed was that dumpxml does not grab the cpuset info. I have not looked at the code to verify, but is this expected? Maybe you discussed this Daniel, but I can't remember at the moment. -- Elizabeth Kon (Beth) IBM Linux Technology Center Open Hypervisor Team email: eak(a)us.ibm.com

[Libvir] [PATCH] Enhanced stats for fullvirt domains
by Richard W.M. Jones 14 Nov '07

14 Nov '07

This patch does a couple of primary things: Firstly it allows you to use "hda", etc. as a path for getting block device stats from fullvirt domains. Secondly it separates out the stats code into a new file called 'stats_linux.c'. The reasoning behind the name is that this code can be shared between Xen & QEMU, and that the code is Linux-specific (it never worked on Solaris, but now this is explicit). I anticipate a 'stats_solaris.c' file once I can get Solaris + Xen going on a test machine. Also we try to detect the case where the block dev stats of a fullvirt domain are stuck at 0 -- caused by there being no frontend driver connected. We detect the condition by a query to xenstore. XENVBD_MAJOR is no longer hard-coded if we can get it instead from Linux header files. This patch adds bytes written/read to block devices for Xen PV domains if available. This also corrects a bug where stats from xvdb, xvdc, .. could not be read out because the device number was being miscalculated.

[Libvir] [PATCH] Fix xen://hostname URIs with no trailing slash
by Richard W.M. Jones 14 Nov '07

14 Nov '07

It turns out that xmlParseURI gives an error if asked to parse the string "xen://". This string arises because after a URI such as "xen://hostname" has been stripped of its server field, it becomes "xen://" on the remote end of the connection, and the failure of xmlParseURI causes the whole connection to fail. I'm not sure of the best way to fix it. The attached patch is a semi-hack which at least allows xen://hostname to work. It's not a problem for qemu because these URIs should always contain a path. Nor for test for the same reason. Not sure about OpenVZ.

[Libvir] [PATCH] parse URI once in src/libvirt.c, pass parsed URI to all drivers
by Richard W.M. Jones 14 Nov '07

14 Nov '07

The basic change here is that the virDrvOpen call (the internal "open" call for drivers) now takes the parsed xmlURIPtr instead of the raw name string. typedef virDrvOpenStatus (*virDrvOpen) (virConnectPtr conn, - const char *name, + xmlURIPtr uri, int flags); So we avoid the redundant URI parsing which was going on inside all the drivers, and also the ad-hoc "does-it-look-like-a-URI" string comparisons. That's straightforward enough except that all of the drivers were saving the name string in their private data so that they could implement the virConnectGetURI call. I've changed this so that the name is copied and saved in the main virConnect structure, and virConnectGetURI will return that unless the driver wants to override it. You need another patch (coming shortly) to allow URIs like xen://localhost (without the trailing slash) to work, which was IIRC the original point of this discussion.

[Libvir] [PATCH] Parse integers more carefully, cont'd.
by Jim Meyering 13 Nov '07

13 Nov '07

Here's part two in the strtol fix-up series: Parse integers more carefully, cont'd. * qemud/qemud.c: Replace uses of strtol with uses of xstrtol_i. Avoid overflow for very large --timeout=N values. * src/nodeinfo.c: In linuxNodeInfoMemPopulate and linuxNodeInfoCPUPopulate, use xstrtol_i rather than strtol. Unlike in qemud.c, here we allow trailing "isspace", and in the case of "cpuinfo cpu MHz", also allow a "." terminator, since we ignore the decimal and any following digits. * src/internal.h: Define xstrtol_iu, too.
