It's a libvirt thing. Replies redirected to libvir-list. My understanding is that if the network doesn't contain a <ip...> element in the network XML then no DHCP server will be created. http://libvirt.org/formatnetwork.html Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.

[Libvir] Can't connect to lxc driver
by Dave Leskovec 01 May '08

01 May '08

Hi Dan, I updated today to the latest CVS and can no longer connect to the lxc driver. I've tracked it down to this check in doRemoteOpen() in remote_internal.c: if (( #ifdef HAVE_XMLURI_QUERY_RAW uri->query_raw = #else uri->query = #endif qparam_get_query (vars)) == NULL) goto failed; Looking at the recent VirBuffer changes, it looks like they changed the behavior of qparam_get_query. With the old VirBuffer, qparam_get_query returned a non-NULL result because virBufferNew allocated space. The new VirBuffer doesn't allocate space until something is added and hence this function returns NULL if nothing is ever put in the buffer. I'm not familiar enough with the intended behavior to know what the fix should be here. Thanks! -- Best Regards, Dave Leskovec IBM Linux Technology Center Open Virtualization

[Libvir] build problems on RHEL5, at least some are now fixed
by Jim Meyering 01 May '08

01 May '08

Daniel Berrange noticed some build problems on RHEL5. Some were due to my not adding two .m4 files in yesterday's gnulib update. [excuse time ;-) Normally (in other projects), the gnulib-update process is automatic, since the imported files are not version-controlled, but for libvirt I have to identify new files pulled in by a gnulib update, and obviously didn't complete that step. Identifying and adding added files is not hard. Just have to remember to do it before committing anything. Actually, the trick is (as usual) to *automate* the process, so we don't have to depend on my memory. This is now on my list. Anyhow, I've committed the change.

[Libvir] PATCH: Autogenerate table of contents for docs
by Daniel P. Berrange 30 Apr '08

30 Apr '08

Alot of the docs pages have manually written table of contents linking to headings with the page. I figured this is a good candidate for being auto-generated. The basic idea is that given a document with a series of headings <h2><a name="xxx">Foo</a></h2> .. <h3><a name="xxx">Bar</a></h3> .. <h3><a name="xxx">Wizz</a></h3> .. <h2><a name="xxx">Oooh</a></h2> .. <h3><a name="xxx">Ahhh</a></h3> Then, generate a table of contents with a nested set of lists <ul>. THe XSL below attempts todo this for heading levels h2 -> h6, and splices the TOC into the page where it sees an <ul id='toc'></ul> element (typically just after <h1>). I'm kind of out of practice with XSL, so there's probably a nicer way to write the 'toc' template below... Dan.

[Libvir] [PATCH] remove useless tests before xmlFree
by Jim Meyering 29 Apr '08

29 Apr '08

I've just fixed a bug in my useless-if-detecting script, committed in gnulib. Using that new script with today's change adding xmlFree to the list exposed a bunch of useless tests. This first change set removes those tests. Below it is a separate patch that updates gnulib-related files, including that script and vc-list-files. I verified that with these changes "make distcheck" passes. If no one objects, I'll push these in about 12 hours. remove useless tests before xmlFree * src/qemu_conf.c (qemudParseDiskXML, qemudParseInterfaceXML): (qemudParseInputXML, qemudParseDhcpRangesXML): * src/remote_internal.c (doRemoteOpen): * src/storage_conf.c (virStoragePoolDefParseDoc): * src/xm_internal.c (xenXMParseXMLDisk, xenXMParseXMLVif): (xenXMParseXMLToConfig, xenXMAttachInterface): * src/xml.c (virDomainParseXMLDiskDesc, virDomainParseXMLIfDesc): (virDomainXMLDevID): Signed-off-by: Jim Meyering <meyering(a)redhat.com> --- src/qemu_conf.c | 48 ++++++++++++++++-------------------------------- src/remote_internal.c | 8 ++++---- src/storage_conf.c | 3 +-- src/xm_internal.c | 42 ++++++++++++++---------------------------- src/xml.c | 30 ++++++++++-------------------- 5 files changed, 45 insertions(+), 86 deletions(-) diff --git a/src/qemu_conf.c b/src/qemu_conf.c index 07dfe47..a0c4a8f 100644 --- a/src/qemu_conf.c +++ b/src/qemu_conf.c @@ -680,14 +680,10 @@ static int qemudParseDiskXML(virConnectPtr conn, return 0;

[Libvir] Basic VMWare support

Hi, I know that there is no support for VMWare ESX yet but I would like to know if someone is working on it. I need just three basic operations: status/power on/power off but I never saw the source code of libvirt :) Do you think it is possible to write this support (using VMWare API) in acceptable time? week? month? Thanks, for any suggestions m, -- Marek Grac Red Hat Czech s.r.o.
