[libvirt] [PATCH] build: fix virBufferVasprintf on mingw
by Eric Blake 06 Jul '11

06 Jul '11

Gnulib documents that mingw [v]snprintf is broken (it returns -1 on out-of-space, instead of the count of what would have been printed); but while we were using the snprintf wrapper, we had not yet been using the vsnprintf wrapper. * bootstrap.conf (gnulib_modules): Add vsnprintf.

[libvirt] [PATCH] Fix default value of security label 'relabel' attribute
by Daniel P. Berrange 06 Jul '11

06 Jul '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> When no <seclabel> is present in the XML, the virDomainSeclabelDef struct is left as all zeros. Unfortunately, this means it gets setup as type=dynamic, with relabel=no, which is an illegal combination. Change the 'bool relabel' attribute in virDomainSeclabelDef to the inverse 'bool norelabel' so that the default initialization is sensible * src/conf/domain_conf.c, src/conf/domain_conf.h, src/security/security_apparmor.c, src/security/security_selinux.c: Replace 'relabel' with 'norelabel' --- src/conf/domain_conf.c | 18 +++++++++--------- src/conf/domain_conf.h | 2 +- src/security/security_apparmor.c | 8 ++++---- src/security/security_selinux.c | 20 ++++++++++---------- 4 files changed, 24 insertions(+), 24 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 109a947..b74ab4d 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -5076,25 +5076,25 @@ virSecurityLabelDefParseXML(const virDomainDefPtr def, VIR_SECURITY_LABEL_BUFLEN-1, ctxt); if (p != NULL) { if (STREQ(p, "yes")) { - def->seclabel.relabel = true; + def->seclabel.norelabel = false; } else if (STREQ(p, "no")) { - def->seclabel.relabel = false; + def->seclabel.norelabel = true; } else { virDomainReportError(VIR_ERR_XML_ERROR, _("invalid security relabel value %s"), p); goto error; } if (def->seclabel.type == VIR_DOMAIN_SECLABEL_DYNAMIC && - !def->seclabel.relabel) { + def->seclabel.norelabel) { virDomainReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("dynamic label type must use resource relabeling")); goto error; } } else { if (def->seclabel.type == VIR_DOMAIN_SECLABEL_STATIC) - def->seclabel.relabel = false; + def->seclabel.norelabel = true; else - def->seclabel.relabel = true; + def->seclabel.norelabel = false; } /* Only parse label, if using static labels, or @@ -5114,7 +5114,7 @@ virSecurityLabelDefParseXML(const virDomainDefPtr def, } /* Only parse imagelabel, if requested live XML with relabeling */ - if (def->seclabel.relabel && + if (!def->seclabel.norelabel && !(flags & VIR_DOMAIN_XML_INACTIVE)) { p = virXPathStringLimit("string(./seclabel/imagelabel[1])", VIR_SECURITY_LABEL_BUFLEN-1, ctxt); @@ -9890,15 +9890,15 @@ char *virDomainDefFormat(virDomainDefPtr def, (flags & VIR_DOMAIN_XML_INACTIVE)) { virBufferAsprintf(&buf, " <seclabel type='%s' model='%s' relabel='%s'/>\n", sectype, def->seclabel.model, - def->seclabel.relabel ?

[libvirt] problems with <seclabel> when restarting libvirtd
by Laine Stump 05 Jul '11

05 Jul '11

I had libvirtd build from 0.9.2+something running on my test machine. There was a single guest running on it. I grabbed the latest libvirt from git (0.9.3+??), built an rpm, and installed it. My guest reconnected with no problems, but I was unable to start new guests due to an selinux problem with the labeling of the image file. Interestingly, I found that I could shutdown and restart the one guest that had been running at the time of the upgrade. *Until* I restarted libvirtd again while the guest was stopped. After this point, I could no longer start that guest either. I then set selinux to permissive mode and was able to start my original guest. Then I restarted libvirtd and found that, although the qemu-kvm process was still running, libvirtd couldn't reconnect to the guest. When I looked at the logs, I saw this: error: virSecurityLabelDefParseXML:5073 : unsupported configuration: dynamic label type must use resource relabeling In the domain state file, I see this: | <seclabel type='dynamic' model='selinux' relabel='no'> | <label>system_u:system_r:svirt_t:s-:c419,c955</label> | </seclabel> The data in the state file was written by the same version of libvirtd that wrote it. So why did it write something it knows it doesn't support?

[libvirt] Duplicate symbol error with 0.9.3 on OSX
by Justin Clift 05 Jul '11

05 Jul '11

Hi all, Just went to update the OSX libvirt build for 0.9.3, but it's giving a duplicate symbol error: ld: duplicate symbol _virNetworkDNSHostsDef in ./.libs/libvirt_driver_test.a(libvirt_driver_test_la-test_driver.o) and ./.libs/libvirt_conf.a(libvirt_conf_la-network_conf.o) "virNetworkDNSHostsDef" is definitely in src/conf/network_conf.*, but not seeing it anywhere in src/test/test_driver.*. Anyone have suggestions on what to look at? Regards and best wishes, Justin Clift -- Aeolus Community Manager http://www.aeolusproject.org

[libvirt] [PATCH] Quieten build & ensure API build scripts exit with non-zero status
by Daniel P. Berrange 05 Jul '11

05 Jul '11

The current API build scripts will continue and exit with a zero status even if they find problems. This has been the cause of many build problems, or hidden build errors, in the past. Change the scripts so they always exit with a non-zero status for any problems they do not understand. Also turn off all debug output by default so they respect $(AM_V_GEN) * docs/Makefile.am: Use $(AM_V_GEN) for API/HTML scripts * docs/apibuild.py, python/generator.py: Exit with non-zero status if problems are found. Also be silent, not outputting any debug messages. * src/Makefile.am: Use $(AM_V_GEN) for ESX generator * python/Makefile.am: Tweak rule --- docs/Makefile.am | 11 ++---- docs/apibuild.py | 95 ++++++++++++++++++++++++++++++-------------------- python/Makefile.am | 6 ++-- python/generator.py | 16 +++++--- src/Makefile.am | 2 +- 5 files changed, 75 insertions(+), 55 deletions(-) diff --git a/docs/Makefile.am b/docs/Makefile.am index 050ebe1..e7d356e 100644 --- a/docs/Makefile.am +++ b/docs/Makefile.am @@ -153,21 +153,18 @@ internals/%.html.tmp: internals/%.html.in subsite.xsl page.xsl sitemap.html.in html/index.html: libvirt-api.xml newapi.xsl page.xsl sitemap.html.in -

[libvirt] [PATCH] qemu: Add support for SGA video
by Michal Privoznik 04 Jul '11

04 Jul '11

This patch extends possible values for <video> element. Serial Graphics Adapter allows users to see BIOS messages from the very first moment domain boots up. Therefore, users can choose boot medium, set PXE, etc. However, to be able to use this, one need SGABIOS, which is accessible here: http://code.google.com/p/sgabios/ --- docs/formatdomain.html.in | 5 +++-- docs/schemas/domain.rng | 1 + src/conf/domain_conf.c | 43 ++++++++++++++++++++++++------------------- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 28 ++++++++++++++++++++++------ 5 files changed, 51 insertions(+), 27 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 3a64983..2d89b37 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -2005,8 +2005,9 @@ qemu-kvm -net nic,model=? /dev/null <dd> The <code>model</code> element has a mandatory <code>type</code> attribute which takes the value "vga", "cirrus", "vmvga", "xen", - "vbox", or "qxl" (since 0.8.6) - depending on the hypervisor features available. + "vbox", "qxl" (since 0.8.6), or "sga" + (Since 0.9.4) depending on the hypervisor + features available.

[libvirt] VMWare "independent disk" processing needed
by computernews＠rambler.ru 04 Jul '11

04 Jul '11

Hello, On VMware ESX server it is possible for the virtual machine to add the "independent disk" - the kind of virtual disk that (among other features) is not being covered by the snapshot logic. As I am working on some kind of backup solution I need to be able to backup the precise state of the guest virtual machine running on say VMware ESX server. I am able to perform a backup of a guest machine description with libvirts's amazing API which covers most of my needs except the aforementioned "independent disk" virtual disk type. The problem shows up at the restore type when I need to create the new virtual machine having an .xml file created by "virsh dumpxml" command. In fact I use API but "virsh does the same". This .xml file covers most of guest machine's aspects but it doesn't reflect the "independent" nature of such disks. So the virtual machine is going to be restored incorrectly when includes "independent disks". From the source codes of "libvirt" ("/libvirt/src/vmx/vmx.*") I see that this is ment to be covered but yet is not implemented. Appropriate nodes must be stored in .xml file during the backup and returned back to .vmx file during the restore. So here are my questions: Is someone on it at the moment ? If yes - can I help somehow ? If no - whom shell I approach in order to be mentored/directed if I decide to participate, implement this and contribute the patch back to the source code ? Thanks for an answer in advance. Best regards Oleh Paliy
