[libvirt] [PATCH] split out logfile opening
by Guido Günther 11 Jan '09

Hi, attached patch splits out the qemu logfile opening into a separate function which makes the code a bit more readable and I'll need this for the libvirtd restart code. Cheers, -- Guido

[libvirt] Libvirt - Xen Enterprise - Koan

Hi I hope me "replying" this way does not break anyone's mail sorting, I only now subscribed to the list. > Thanks for this - this sounds like the most likely issue. The problem is > that Citrix seems to move things around somewhat as that config file > does not exist. There is a xensource directory that contains the > following but other than that i am a bit stuck. They might have overriden the config file to point somewhere else. Try and find the file "XendOptions.py" and see where it loads the config from. Or see if anything sets $XEND_CONFIG env variable at startup. In regular upstream xen code, it XendOptions.py has: class XendOptionsFile(XendOptions): """Default path to the config file.""" config_default = "/etc/xen/xend-config.sxp" I did a find . -name *.py > temp.gg and then 141 cat temp.gg | xargs grep -i xendoptions 142 cat temp.gg | xargs grep -i xend 144 cat temp.gg | xargs grep -i XEND_CONFIG 148 cat temp.gg | xargs grep -i config_default All of these searches gave me absolutely no results. I am sure that the config files are in : /etc/xensource/ xapi.conf xapi-ssl.conf the contents of xapi.conf is: schema_filename = /etc/xensource/db_schema.sql license_filename = /etc/xensource/license http-port = 80 use-ssl = true ssl-cert = /etc/ssl/certs/xensource-rio.pem ssl-port = 443 # dom0-mem = 128 and of xapi-ssl.conf is: pid = /var/run/xapi.ssl.pid socket = r:TCP_NODELAY=1 socket = a:TCP_NODELAY=1 socket = l:TCP_NODELAY=1 [xapi] accept = 443 connect = 80 cert = /etc/xensource/xapi-ssl.pem I am thinking that maybe only ssl connections are allowed ... which is why virsh can't connect? we are running "XenServer release 4.1.0-7843p (xenenterprise)" and I am trying to get spacewalk to get the necessary domain details when registering a xen host. ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.

Attached patch adds a flag parameter to the above functions and passes VIR_DOMAIN_XML_INACTIVE from the upper levels. I see two advantages in this: * symmetric interfaces to the XML parsing functions (why has virDomainDefParseFile a flags argument while virDomainDefParseString hasn't) * other drivers can use this very easily (IIRC lxc has some use for it) otherwise there's not too much gain so I'm a bit undecided if this is actually necessary. -- Guido

[libvirt] PATCH: Thread-safe error reporting public API
by Daniel P. Berrange 07 Jan '09

07 Jan '09

The current public API for error reporting consists of - A global error object - A per-connection error object Some functions always set errors on the global object. Other functions always set errors on the per-connection object, except when they set errors on the global object. Both have built-in race conditions if they are accessed from multiple threads because of the time between the API call raising the error, and the caller querying it. The solution to this is to do away with all of the existing error objects and replace them with a per-thread error object. Well, except we can't do away with existing objects because of ABI compatability. This turns out to not be such a bad problem after all.... So with this patch... virterror.c gets ability to track a per-thread virErrorPtr instance. This object is stored in a thread local variable via pthread_{get,set}specific. It is allocated when first required, and deleted when the thread exits Every single API will *always* set the virErrorPtr object associated with its current thread. In the public virterror.h we add virErrorPtr virThreadGetLastError (void); int virThreadCopyLastError (virErrorPtr to); void virThreadResetLastError (void); This provides a guarenteed thread-safe public API for fetching error information. All the other existing APIs have docs updated to recommend against their use. In libvirt.c, in any exit paths which result in an error code, we copy the per-thread virErrorPtr object into either the global error object or per-connection object as applicable for the scenario. This gives us 100% backwards compatability. NB, we hold a lock when doing this so that these are race-free when setting them. At the start of every API call, we call virThreadResetLastError() and at any exit path with an error, if the error object is not set, then we set a generic error message. This means that if the internal driver code is broken and forgets to raise an error, the caller will still at least see a generic error report. Finally, virCopyLastError and virConnCopyLastError were not correctly strdup'ing the char * fields. This meant that if the original error was cleared, you'd get a use-after-free error, shortly followed by a double-free error if the first didn't kill you. This patch also fixes those two methods to correctly strdup the char *. As for language bindings, they should *all* be updated to use the virThreadGetLastError() method, and *never* call virGetLastError() or the virConnGetLastError() calls. With this patch applied, assuming all the per-hypervisor drivers are thread-safe (they are except for Xen which is still TODO), then the public API for virConectPtr is also (almost[1]) guarenteed to be thread- safe. include/libvirt/virterror.h | 7 src/datatypes.c | 11 src/datatypes.h | 15 src/libvirt.c | 3729 ++++++++++++++++++++++++++++++-------------- src/libvirt_sym.version.in | 8 src/virterror.c | 281 +++ src/virterror_internal.h | 4 7 files changed, 2902 insertions(+), 1153 deletions(-) Daniel [1] We need to fix lots of stupid internal mistakes like strerror() vs strerror_r() - these were already a problem even with libvirt being single-threaded on virConnectPtr, because the app using libvirt could be threaded.

[libvirt] 3 small patches
by Jim Meyering 07 Jan '09

07 Jan '09

1: cvs-ignore a stray, generated file 2: bootstrap: pull in gnulib's ioctl module (Daniel Berrange will use it shortly) 3: add more files pulled in via yesterday's gnulib upgrade The third is highest priority, since without it, running autogen.sh from just-checked-out sources fails due to 3 missing .m4 files. This isn't the first time that's happened. I tracked the problem to the way gnulib-tool updates .cvsignore files to mark pulled-in files as ignored, by default. That made it hard to use vc tools like cvs or git to identify new files. The 2nd patch adds gnulib-tools' --no-vc-files option to inhibit that behavior. >From 4b63b91ff4b8308cfde641686ea22ff51499bb00 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Wed, 7 Jan 2009 15:43:41 +0100 Subject: [PATCH 1/3] ignore generated libvirtd.logrotate. * qemud/.cvsignore: Add libvirtd.logrotate. * qemud/.gitignore: Regenerate. --- qemud/.cvsignore | 13 +++++++------ qemud/.gitignore | 13 +++++++------ 2 files changed, 14 insertions(+), 12 deletions(-) diff --git a/qemud/.cvsignore b/qemud/.cvsignore index 04fed54..38cf28d 100644 --- a/qemud/.cvsignore +++ b/qemud/.cvsignore @@ -1,11 +1,12 @@ -Makefile -Makefile.in +*.gcda +*.gcno +*.la +*.lo .deps .libs -*.lo -*.la +Makefile +Makefile.in libvirt_qemud libvirtd libvirtd.init -*.gcno -*.gcda +libvirtd.logrotate diff --git a/qemud/.gitignore b/qemud/.gitignore index 04fed54..38cf28d 100644 --- a/qemud/.gitignore +++ b/qemud/.gitignore @@ -1,11 +1,12 @@ -Makefile -Makefile.in +*.gcda +*.gcno +*.la +*.lo .deps .libs -*.lo -*.la +Makefile +Makefile.in libvirt_qemud libvirtd libvirtd.init -*.gcno -*.gcda +libvirtd.logrotate -- 1.6.1.121.g866a4a >From 8d6654775a277eca6bf52b011671920091cde9a4 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Wed, 7 Jan 2009 16:11:02 +0100 Subject: [PATCH 2/3] bootstrap: pull in gnulib's ioctl module * bootstrap: Invoke gnulib-tool with its --no-vc-files option, since we version-control the files it imports.

[libvirt] patch for pci passthrough
by Jason Krieg 07 Jan '09

07 Jan '09

Hi, This patch adds support for the -pcidevice host=bus:dev.func added in kvm-79 I used the structure as already defined in src/domain_conf.h so analog to usb one now can add pci devices as example: lspci: 06:02.0 Network controller: Eicon Networks Corporation Diva Server 2FX (rev 01) <hostdev mode='subsystem' type='pci'> <source> <address bus="0x06" slot="0x02" function="0x0"/> </source> </hostdev> values are hex so for bus: 0 to ff, slot: 0 to 1f and function: 0 to 7 Hope this patch is useful it applies to libvirt-0.5.1 and cvs checkout from today (with some hunks) Regards Jason -- Collax GmbH . Burkheimer Str. 3 . 79111 Freiburg . Germany p: +49 (0) 89-990157-0 f: +49 (0) 89-990157-11 . http://www.collax.com
