Don't add things to xenUnifiedDriver structure -- this structure should go away eventually. (See the comment in src/xen_unified.h). Instead, just do whatever you need directly from src/xen_unified.c, be that direct code or calling something lower level. > code stuffed with debugging printfs: > > #if 0 case: > > priv->opened[i]: 0 > drivers[i]->domainGetInfo: 0x2aaaaaae0c10 > priv->opened[i]: 1 > drivers[i]->domainGetInfo: 0x2aaaaaaec2c0 > Domains 0: 2 CPUs > > #if 1 case: > > priv->opened[i]: 0 > drivers[i]->domainGetInfo: (nil) > priv->opened[i]: 1 > drivers[i]->domainGetInfo: (nil) > priv->opened[i]: 0 > drivers[i]->domainGetInfo: 0x2aaaaaae7400 > priv->opened[i]: 0 > drivers[i]->domainGetInfo: (nil) > priv->opened[i]: 1 > drivers[i]->domainGetInfo: (nil) > Failed to get informations for Domain 0 > > as you can see the "drivers" (xenHypervisorDriver etc.) got > redefined... > > any idea why? or whats going on? > > thnx for any possible help, if you cannot help me could you please > forward this mail to the appropriete place?

[Libvir] libvirt & vde_switch
by Loic Dachary 05 Feb '08

05 Feb '08

In reply to http://www.redhat.com/archives/libvir-list/2007-April/msg00177.html an area where vde_switch support is usefull is an unprivileged user running tests. A test suite involving the creation of qemu instances thru libvirt should not be forced to create a bridge or alter the iptables configuration. With vde_switch and slirpvde multiple qemu instances can be run without altering the network configuration of the host. I hope it helps. Cheers

[Libvir] mark some diagnostics for translation
by Jim Meyering 04 Feb '08

04 Feb '08

This makes it so some diagnostics emitted via the error function are checked for use of "_(...)" when you run "make syntax-check", and fixes the ones that lacked that: Enable the sc_unmarked_diagnostics test and correct all violations involving the "error" function. * Makefile.cfg (local-checks-to-skip): Remove from skip list. Then, at the end, a second patch: Mark a string for translation. * src/virsh.c: Add a "%s" and wrap with _(...). Note that technically, it doesn't make sense to translate a diagnostic like this (there are several like this): error (conn, VIR_ERR_RPC, _("maxids > REMOTE_DOMAIN_ID_LIST_MAX")); However, if it's worth emitting the diagnostic, then I think it's worth making it a little more useful to someone not reading the code, e.g., too many domains (maximum is %d) If no one objects, I'll convert the ones below.

[Libvir] mark more translatable messages
by Jim Meyering 04 Feb '08

04 Feb '08

This change marks for translation some more messages. It adds a few new ones, too, e.g., replacing "domain" with _("failed to parse domain description") in two places. Likewise, there are some like this: - virXendError (conn, VIR_ERR_NO_MEMORY, "strdup"); + virXendError (conn, VIR_ERR_NO_MEMORY, _("strdup failed")); The two new grep invocations in Makefile.maint handle two situations: First, when the entire statement is on a single line (ends in ";"). The second grep (with -A1) is to get the diagnostics that appear on the line following the function name. Hence where the first line ends in ",". With checks like this, it's nice if you can assume no trailing blanks in the code base. IMHO, that would be a nice change to make soon, but it's more invasive. Enable more checks for unmarked messages; fix violators. * Makefile.maint (sc_unmarked_diagnostics): Check for more functions. * src/conf.c (virConfParseValue): Remove trailing space in diagnostic. * src/libvirt.c (do_open, virDomainMigrate): Mark diagnostics. * src/xend_internal.c (do_connect, xenDaemonDomainDumpXMLByID): Likewise. (xenDaemonDomainDumpXMLByName, xenDaemonCreateLinux): Likewise. (xenDaemonDomainMigratePerform, xenDaemonDomainDefineXML): Likewise. * src/xml.c (virXPathString, virXPathNumber, virXPathLong): Likewise. (virXPathBoolean, virXPathNode, virXPathNodeSet): Likewise.

[Libvir] virsh vncdisplay fix
by John Levon 03 Feb '08

03 Feb '08

I have an old HVM guest defined in 3.0.4, and now I'm running 3.1.2 and libvirt 0.4.0. The config looks like this: (domain (image (hvm (vnc 1) (vncdisplay 0) (device (vfb (location localhost:5900) (vncdisplay 0) (uuid ...) The libvirt code looks like this: 1757 /* Graphics device (HVM <= 3.0.4, or PV <= 3.0.3) vnc config */ 1758 if ((hvm && xendConfigVersion < 4) || 1759 (!hvm && xendConfigVersion < 3)) { 1760 tmp = sexpr_fmt_node(root, "domain/image/%s/vnc", hvm ? "hvm" : "linux"); So we don't see the 'vnc 1' at the top. But the code to parse device/vfb doesn't expect this config either: 1685 tmp = sexpr_node(node, "device/vfb/type"); The patch below replaces the later version check with something that copes correctly with the "upgrade" case. regards john 2008-01-15 John Levon <levon(a)movementarian.org> * src/xend_internal.c: fix VNC parsing of old Xen domains on newer Xen versions. diff -prauN libvirt-0.4.0/src/xend_internal.c libvirt-new/src/xend_internal.c --- libvirt-0.4.0/src/xend_internal.c 2007-12-17 15:05:27.000000000 -0800 +++ libvirt-new/src/xend_internal.c 2008-01-14 18:42:08.895060570 -0800 @@ -1371,6 +1371,7 @@ xend_parse_sexp_desc(virConnectPtr conn, unsigned char uuid[VIR_UUID_BUFLEN]; char uuidstr[VIR_UUID_STRING_BUFLEN]; int vif_index = 0; + int found_graphics = 0; if (root == NULL) { /* ERROR */ @@ -1683,6 +1684,7 @@ xend_parse_sexp_desc(virConnectPtr conn, if (tmp && !strcmp(tmp, "sdl")) { virBufferVSprintf(&buf, " <input type='mouse' bus='%s'/>\n", hvm ?

[Libvir] [PATCH] Pull vc-list-files from gnulib, and update.
by Jim Meyering 01 Feb '08

01 Feb '08

Now that I've added the vc-list-files script to gnulib, this patch makes libvirt's bootstrap pull it from there. Changes from the previous version of the script: I reintroduced support for mercurial (only lightly tested), and rearranged the directory-existence tests so git is first. Here's the full patch, including a renaming in vasnprintf.c: ---------------- Pull vc-list-files from gnulib, and update. * bootstrap (gnulib_tool): Add the vc-list-files module. --- bootstrap | 3 ++- build-aux/vc-list-files | 19 +++++++++++++------ gnulib/lib/Makefile.am | 9 ++++++++- gnulib/lib/vasnprintf.c | 18 ++++++++++-------- gnulib/m4/gnulib-cache.m4 | 4 ++-- gnulib/m4/gnulib-comp.m4 | 1 + 6 files changed, 36 insertions(+), 18 deletions(-) diff --git a/bootstrap b/bootstrap index 751b244..1627086 100755 --- a/bootstrap +++ b/bootstrap @@ -77,7 +77,8 @@ $gnulib_tool \ --tests-base=gnulib/tests \ --import physmem getaddrinfo \ sys_stat vasprintf strndup \ - strsep poll gettext getpass + strsep poll gettext getpass \ + vc-list-files rm -f \ .gitignore \ diff --git a/build-aux/vc-list-files b/build-aux/vc-list-files index 72a6f54..1e158bb 100755 --- a/build-aux/vc-list-files +++ b/build-aux/vc-list-files @@ -1,7 +1,7 @@ #!/bin/sh -# List the specified version-controlled files. +# List version-controlled file names. -# Copyright (C) 2006, 2007 Free Software Foundation, Inc. +# Copyright (C) 2006-2008 Free Software Foundation, Inc. # This program is free software: you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by @@ -18,7 +18,8 @@ # List the specified version-controlled files. -# With no argument, list them all. +# With no argument, list them all.

With a contrived example using more than 20 (the max permitted by the testing framework) domains, I got a double-free error: ==4821== Invalid free() / delete / delete[] ==4821== at 0x4A0560B: free (vg_replace_malloc.c:233) ==4821== by 0x4167F1: virReleaseConnect (hash.c:717) ==4821== by 0x4168E7: virUnrefConnect (hash.c:746) ==4821== by 0x40FCEB: do_open (libvirt.c:621) ==4821== by 0x40FDF1: virConnectOpenAuth (libvirt.c:682) ==4821== by 0x40D5B1: vshInit (virsh.c:4464) ==4821== by 0x40E67C: main (virsh.c:4985) ==4821== Address 0x4C3BA68 is 0 bytes inside a block of size 60 free'd ==4821== at 0x4A0560B: free (vg_replace_malloc.c:233) ==4821== by 0x40FCB3: do_open (libvirt.c:618) ==4821== by 0x40FDF1: virConnectOpenAuth (libvirt.c:682) ==4821== by 0x40D5B1: vshInit (virsh.c:4464) ==4821== by 0x40E67C: main (virsh.c:4985) error: failed to connect to the hypervisor ... here's one way to fix it: diff --git a/src/libvirt.c b/src/libvirt.c index defadc1..c19565f 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -615,7 +615,6 @@ do_open (const char *name, return ret; failed: - free (ret->name); if (ret->driver) ret->driver->close (ret); if (uri) xmlFreeURI(uri); virUnrefConnect(ret); At first, rather than removing the offending free, I inserted this line just after it: ret->name = NULL; which avoids leaking ->name even if some driver-specific close function fails to clean up properly. But IMHO if such a function doesn't clean up properly then *it* should be fixed, not all callers.
