[libvirt] [PATCH] Imprint all logs with version + package build information
by Daniel P. Berrange 27 Jan '11

27 Jan '11

The logging functions are enhanced so that immediately prior to the first log message being printed to any output channel, the libvirt package version will be printed. eg $ LIBVIRT_DEBUG=1 virsh 18:13:28.013: 17536: info : libvirt version: 0.8.7 18:13:28.013: 17536: debug : virInitialize:361 : register drivers ... The 'configure' script gains a '--with-package-string' argument to allow distros to append a custom string with package specific data. The RPM specfile is modified so that it appends the RPM version, the build host, the build date and the packager name. eg $ LIBVIRT_DEBUG=1 virsh 18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10) 18:14:52.086: 17551: debug : virInitialize:361 : register drivers Thus when distro packagers receive bug reports they can clearly see what version was in use, even if the bug reporter mistakenly or intentionally lies about version/builds * src/util/logging.c: Output version data prior to first log message * libvirt.spec.in: Include RPM release, date, hostname & packager * configure.ac: Add --with-package-string arg --- configure.ac | 10 ++++++ libvirt.spec.in | 7 ++++ src/util/logging.c | 86 +++++++++++++++++++++++++++++++++++++++++++--------- 3 files changed, 88 insertions(+), 15 deletions(-) diff --git a/configure.ac b/configure.ac index f310a5e..92d77e4 100644 --- a/configure.ac +++ b/configure.ac @@ -29,6 +29,16 @@ AC_SUBST([LIBVIRT_VERSION]) AC_SUBST([LIBVIRT_VERSION_INFO]) AC_SUBST([LIBVIRT_VERSION_NUMBER]) +AC_ARG_WITH([package-string], + [AS_HELP_STRING([--with-package-string], + [Extra package name/version string])], + [],[]) +if test "x$with_package_string" != "xno" +then + AC_DEFINE_UNQUOTED([PACKAGE_STRING], ["$with_package_string"], + [Extra package name/version string]) +fi + dnl Required minimum versions of all libs we depend on LIBXML_REQUIRED="2.6.0" GNUTLS_REQUIRED="1.0.25" diff --git a/libvirt.spec.in b/libvirt.spec.in index 0a2d10e..43c9067 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -592,6 +592,12 @@ of recent versions of Linux (and other OSes). %define _without_dtrace --without-dtrace %endif +%define when %(date +"%%m-%%d-%%Y-%%H:%%M:%%S") +%define where %(hostname) +%define who %{?packager}%{!?packager:Unknown} +%define with_package_string --with-package-string="%{release} (%{who}, %{when}, %{where})" + + %configure %{?_without_xen} \ %{?_without_qemu} \ %{?_without_openvz} \ @@ -626,6 +632,7 @@ of recent versions of Linux (and other OSes). %{?_without_macvtap} \ %{?_without_audit} \ %{?_without_dtrace} \ + %{with_package_string} \ --with-qemu-user=%{qemu_user} \ --with-qemu-group=%{qemu_group} \ --with-init-script=redhat \ diff --git a/src/util/logging.c b/src/util/logging.c index a80c3e3..5102e06 100644 --- a/src/util/logging.c +++ b/src/util/logging.c @@ -108,6 +108,7 @@ static int virLogNbFilters = 0;

[libvirt] beginner's project
by Eric Blake 27 Jan '11

27 Jan '11

This idea sprang from an IRC conversation, but I don't have time to do it myself at the moment. If you're looking for a great way to help development, it would be nice to teach tests/testutils.c:virtTestLoadFile how to read a file with backslash-newline pairs and flatten those into a single line. Then rewrite all the tests/*data/*.args files to use line continuations, rather than being monstrous 1000-character lines. That way, git send-email will quit griping about the inability to send patches to those files. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCH] event: fix two event-handling bugs
by Eric Blake 27 Jan '11

27 Jan '11

Regression introduced in commit e6b68d7. Prior to that point, handlesAlloc was always a multiple of EVENT_ALLOC_EXTENT, and was an integer (so even if the subtraction wrapped, a negative value was less than the count and did not try to free the handles array). But after that point, VIR_RESIZE_N made handlesAlloc grow geometrically, so handlesAlloc could be 49 when handlesCount was 47, while still freeing off only 10 at a time, and eventually reach handlesAlloc 7 and handlesCount 1. Since (size_t)(7 - 10) is indeed greater than 1, this then tried to free 10 elements, which had the awful effect of nuking the handles array while there were still live handles. Which leads to crashes like this: https://bugzilla.redhat.com/show_bug.cgi?id=670848 * daemon/event.c (virEventDispatchHandles): Cache watch while the lock is still held, as eventLoop.handles might be relocated outside the lock. (virEventCleanupHandles): Avoid integer wrap-around causing us to delete the entire handles array while handles are still active. --- Thanks to Dave Allan for letting me use his faqemu setup for testing this.

[libvirt] Planning for next release and discussions on project process
by Daniel Veillard 27 Jan '11

27 Jan '11

So we are around the end of the month, i.e. the time where I usually come out and suggest to enter a freeze within a few days for the next release. However, looking at the git history I note that we have only around 125 patches commited since 0.8.7 was released and while I'm fairly convinced that time based releases are a really good thing (allowing people to see their patches out within a predictable delay, and allowing the whole ecosystem of distros/users to plan accordingly), it's also time I think to open up the process to the growing (or at least changing) set of people involved in building libvirt. I usually ask if everybody agrees on the next freeze but I have to make the initial selection based on the calendar and my own agenda (or Red Hat one). Other projects I know use things like weekly teleconferences to discuss ther development plans, or IRC meetings. My opinion is that phone is not alway convenient/eficient, IRC has the advantage of being more open (no spoken english barrier), less intrusive, and it's nearly trivial to extract and publish some kind of minutes. But both suffer from the timezone problem, basically if there is meeting time it's gonna be during insane hours for someone somewhere (we have a large set of developpers in the US, Matthias and Dan are in Europe, Justin is in Australia, I'm in China now and I think the Fujitsu developpers too) One possibility could be to use a mix of IRC channel gathering and an Etherpad file (very convenient tool try it), I just created one at http://ietherpad.com/oETnXKdcFf to try this out and put my own sugegstions, then others can come and put their own feedback even if they happen to not be online at the time of the meeting. To come back to the release, maybe we can do 2 release for Jan-Mar since we didn't released early in Jan and Feb is short, so I would suggest to plan a release before Feb 15, entering a freeze around the 7th Feb. This should allow to put in some of the code already reviewed but not yet commited that I spotted: + migration enhancements from Hu Tao and Wen Congyang + integration of locking in the QEmu driver from Dan + cgroup blkio support (lxc and qemu) from Gui Jianfeng + smartcard support from Eric but there is certainly things I forgot, and well people may have specific things they want in ASAP, so let's use IRC (irc.oftc.net #virt) and http://ietherpad.com/oETnXKdcFf and share opinions about next release and features to come, well unless people have a better idea on how to organize ourselves, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [v2] remote: Add extra parameter pkipath for URI

This new parameter allows user specifies where the client cerficate, client key, CA certificate of x509 is, instead of hardcoding it. If 'pkipath' is not specified, and the user is not root, try to find files in $HOME/.pki, as long as one of client cerficate, client key, CA certificate can not be found, use default global location (LIBVIRT_CACERT, LIBVIRT_CLIENTCERT, LIBVIRT_CLIENTKEY, see src/remote/remote_driver.h) e.g. [root@Osier client]# virsh -c qemu+tls://10.66.93.111/system?pkipath=/tmp/pki/client error: Cannot access CA certificate '/tmp/pki/client/cacert.pem': No such file or directory error: failed to connect to the hypervisor [root@Osier client]# ls -l total 24 -rwxrwxr-x. 1 root root 6424 Jan 24 21:35 a.out -rw-r--r--. 1 root root 1245 Jan 23 19:04 clientcert.pem -rw-r--r--. 1 root root 132 Jan 23 19:04 client.info -rw-r--r--. 1 root root 1679 Jan 23 19:04 clientkey.pem [root@Osier client]# cp /tmp/cacert.pem .

[libvirt] Rudimentary (basic) s390x architecture functions for libvirt
by Patrick Siegl 25 Jan '11

25 Jan '11

Hello there, I don't know whether or not you are only interested in the x86 / x86_64 architecture, but I think you could also be interested in the small bit of code which I have programmed. Since the release of libvirt 0.8.5, there is a small bit of s390x architecture code (one line) within libvirt which has given me the impression that you could be interested in my small bit of code. I study 'computer science' at the University of Tuebingen (Germany) and each student has to do a research study during his studies on his way to receiving his diploma. One of my goals is to implement basic s390x functions into libvirt in order to be able to start / create virtual machines on a s390x architecture (i.e. on our IBM Mainframe z9 at the university) more easily. Our Setup is (as just mentioned) an IBM Mainframe z9 on which I have the root access to a zLinux (which runs native on two LPARs) with the OS "SUSE Enterprise 11 SP1" and a kernel 2.6.34. (Our test virtual machine is a copy of the running zLinux.) I have actually implemented my patch into libvirt release 0.8.6 but I think a git patch would be more practical for you, so I have implemented it into git today (see underneath or attachment). The following XML file creates a virtual machine on my zLinux with my git patch which is listed underneath (or attachment). As you can see, there is not much that needs to be done so that libvirt can create rudimentary virtual machines on IBM Mainframe z9 (under an zLinux).

[libvirt] [PATCH] build: avoid corrupted gnulib/tests/Makefile
by Eric Blake 25 Jan '11

25 Jan '11

Running 'make check' can sometimes fail in the gnulib/tests subdirectory, when doing an incremental build, because ./bootstrap generates a Makefile.am that tries to refer to ../../.. instead of ../.., and gets lost. This may be an upstream gnulib bug, where a more elegant solution will present itself in the future: http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/24898 But in the meantime, I was able to reproduce both the issue, and this solution to work around it. * bootstrap.conf (bootstrap_epilogue): Ensure that no stray ../../.. components remain in gnulib/tests/Makefile.in.

[libvirt] [PATCH v5] qemu: sound: Support intel 'ich6' model
by Cole Robinson 24 Jan '11

24 Jan '11

In QEMU, the card itself is a PCI device, but it requires a codec (either -device hda-output or -device hda-duplex) to actually output sound. Specifying <sound model='ich6'/> gives us -device intel-hda -device hda-duplex I think it's important that a simple <sound model='ich6'/> sets up a useful codec, to have consistent behavior with all other sound cards. This is basically Dan's proposal of <sound model='ich6'> <codec type='output' slot='0'/> <codec type='duplex' slot='3'/> </sound> without the codec bits implemented. The important thing is to keep a consistent API here, we don't want some <sound> devs require tweaking codecs but not others. Steps I see to accomplishing this: - every <sound> device has a <codec type='default'/> (unless codecs are manually specified) - <codec type='none'/> is required to specify 'no codecs' - new audio settings like mic=on|off could then be exposed in <sound> or <codec> in a consistent manner for all sound models v2: Use model='ich6' v3: Use feature detection, from eblake Set codec id, bus, and cad values v4: intel-hda isn't supported if -device isn't available v5: Comment spelling fixes Signed-off-by: Cole Robinson <crobinso(a)redhat.com> --- docs/formatdomain.html.in | 5 +- docs/schemas/domain.rng | 1 + src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/qemu/qemu_capabilities.c | 5 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 56 +++++++++++++++++++- .../qemuxml2argv-sound-device.args | 2 +- .../qemuxml2argvdata/qemuxml2argv-sound-device.xml | 1 + tests/qemuxml2argvtest.c | 2 +- 10 files changed, 70 insertions(+), 7 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 859f3fd..e7f65ad 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -1880,8 +1880,9 @@ qemu-kvm -net nic,model=? /dev/null The <code>sound</code> element has one mandatory attribute, <code>model</code>, which specifies what real sound device is emulated.

[libvirt] [v1] remote: Add extra parameter client_pki_dir for URI
by Osier Yang 24 Jan '11

24 Jan '11

This new parameter allows user specifies directory in which the client cerficate, client key, CA certificate reside (the directory path must be absolute), instead of hardcoding it in remote driver. But the hardcoded locations are still kept, and attempt to use them if the required files can not be found in the location user specified. e.g. [root@Osier client]# virsh -c qemu+tls://$hostname/system?client_pki_dir\ > =/tmp/pki/client Welcome to virsh, the virtualization interactive terminal.

[libvirt] [PATCH v3] qemu: sound: Support intel 'ich6' model
by Cole Robinson 24 Jan '11

24 Jan '11

In QEMU, the card itself is a PCI device, but it requires a codec (either -device hda-output or -device hda-duplex) to actually output sound. Specifying <sound model='ich6'/> gives us -device intel-hda -device hda-duplex I think it's important that a simple <sound model='ich6'/> sets up a useful codec, to have consistent behavior with all other sound cards. This is basically Dan's proposal of <sound model='ich6'> <codec type='output' slot='0'/> <codec type='duplex' slot='3'/> </sound> without the codec bits implemented. The important thing is to keep a consistent API here, we don't want some <sound> devs require tweaking codecs but not others. Steps I see to accomplishing this: - every <sound> device has a <codec type='default'/> (unless codecs are manually specified) - <codec type='none'/> is required to specify 'no codecs' - new audio settings like mic=on|off could then be exposed in <sound> or <codec> in a consistent manner for all sound models One difference from danpb's suggestion is that the codec id takes the form ${soundid}-codec-${cad}, rather than codec${soundid}${cad}, just for readability. Also, QEMU seems to set the bus name as ${soundid}.0. Is that expected? Or should it just be ${soundid}? v2: Use feature detection, from eblake Set codec id, bus, and cad values Signed-off-by: Cole Robinson <crobinso(a)redhat.com> --- docs/formatdomain.html.in | 5 +- docs/schemas/domain.rng | 1 + src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/qemu/qemu_capabilities.c | 5 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 61 ++++++++++++++++++-- .../qemuxml2argv-sound-device.args | 2 +- .../qemuxml2argvdata/qemuxml2argv-sound-device.xml | 1 + tests/qemuxml2argvdata/qemuxml2argv-sound.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-sound.xml | 1 + tests/qemuxml2argvtest.c | 2 +- 12 files changed, 74 insertions(+), 11 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 859f3fd..e7f65ad 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -1880,8 +1880,9 @@ qemu-kvm -net nic,model=? /dev/null The <code>sound</code> element has one mandatory attribute, <code>model</code>, which specifies what real sound device is emulated.

[libvirt] [PATCH v2] qemu: sound: Support intel 'ich6' model
by Cole Robinson 21 Jan '11

21 Jan '11

In QEMU, the card itself is a PCI device, but it requires a codec (either -device hda-output or -device hda-duplex) to actually output sound. We set up an hda-duplex codec by default: I think it's important that a simple <sound model='ich6'/> sets up a useful codec, to have consistent behavior with all other sound cards. This is basically Dan's proposal of <sound model='ich6'> <codec type='output' slot='0'/> <codec type='duplex' slot='3'/> </sound> without the codec bits implemented. The important thing is to keep a consistent API here, we don't want some <sound> models to require tweaking codecs but not others. Steps I see to accomplishing this when someone gets around to it: - every <sound> device has a <codec type='default'/> (unless codecs are manually specified) - <codec type='none'/> is required to specify 'no codecs' - new audio settings like mic=on|off could then be exposed in <sound> or <codec> in a consistent manner for all sound models Signed-off-by: Cole Robinson <crobinso(a)redhat.com> --- docs/formatdomain.html.in | 5 ++- docs/schemas/domain.rng | 1 + src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 24 ++++++++++++++++--- .../qemuxml2argv-sound-device.args | 2 +- .../qemuxml2argvdata/qemuxml2argv-sound-device.xml | 1 + tests/qemuxml2argvdata/qemuxml2argv-sound.args | 2 +- tests/qemuxml2argvdata/qemuxml2argv-sound.xml | 1 + 9 files changed, 31 insertions(+), 9 deletions(-) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index e9fcea1..b9b83c2 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -1663,8 +1663,9 @@ qemu-kvm -net nic,model=? /dev/null The <code>sound</code> element has one mandatory attribute, <code>model</code>, which specifies what real sound device is emulated.

[libvirt] [RFC] libxenlight driver
by Jim Fehlig 21 Jan '11

21 Jan '11

I'm looking into creating a driver for the new Xen xl/libxl toolstack (aka libxenlight [1]), set to become the default in upcoming Xen 4.1.0 release. My first hurdle is deciding whether this should be a new driver or integrated with existing xen-unified driver. Initially I thought a new driver would be a better approach - a clean break from the old code, similar to the xenapi driver. libxenlight is also stateless (no managed domains), which seems like another good argument for a new driver. But libxenlight is really just another interface into the same hypervisor, so in that regard it should be a xen-unified subdriver. There are certainly benefits to the xen-unified subdriver approach, e.g. the existing hypervisor and xenstore subdrivers can be leveraged, the former providing all the capabilities code. But AFAIK, libxenlight and xend should not be used together, so I don't think we would want the xend subdriver activated if libxenlight is detected. Supposedly xl can be used as a direct replacement for xm, allowing unconditional use of that subdriver. BTW, Ian Jackson responded [2] to some of my questions regarding compatibility between old and new toolstack if you are interested. I'd like to hear other's opinions on a new driver vs. a xen-unified subdriver.

[libvirt] [RFD] Add/Modify some API functions about Host Information
by Minoru Usui 21 Jan '11

21 Jan '11

Hi, everyone In an environment with multiple host machines, I want to select a suitable host automatically on which I run a VM depending on machine's load. Libvirt has APIs to get host machine's information, but I think these APIs aren't enough for above purpose. So I suggest below changes. What do you think? * virNodeGetInfo() This API can get "CPU frequency"(mhz member of virNodeInfo) from "cpu MHz" of /proc/cpuinfo. This value isn't constant, because it may be decrease by power saving feature.(cf. cpuspeed on RHEL) This value is very useful for getting *present* cpu frequency, but I want to get Maximum CPU frequency, too. I want to add max_mhz member in struct virNodeInfo from /sys/device/system/cpu/cpuXX/cpufreq/cpuinfo_max_freq. * virNodeGetFreeMemory() This API returns amount of free memory of the host machine's all node, but this value doesn't include host's cache/buffer memory. For above purpose, it would be more suitable to account cache/buffer as free memory, because most of cache/buffer memory are reclaimable. But I think virNodeGetFreeMemory()'s ABI should not change easily. I want to add function virNodeGetCacheBufferMemory(). It returns amount of cache + buffer memory from /proc/meminfo. * virSysinfoRead() This API is completely internal. But DMI type1 information(dmidecode -t1) is useful for above purpose, because it's one of the information which suppose to processing capacity about host machine. I want to export virSysinfoRead() to user. -- Minoru Usui <usui(a)mxm.nes.nec.co.jp>

[libvirt] [PATCH] Add support for multiple serial ports to Xen driver
by Michal Novotny 20 Jan '11

20 Jan '11

Hi, this is the patch for to support multiple serial ports for Xen driver. The definition for Xen has been introduced in BZ #614004 and this is adding support to libvirt-based tools. The patch was originally written for RHEL-5 and libvirt 0.8.2 (RHEL-5.6) where it has been tested using the virsh command and correct device creation has been confirmed in the xend.log to have the same data for serial ports using both `xm create` and `virsh start` commands. Also, domains with both single and multiple serial ports has been tested to confirm it won't introduce any regression and everything was working fine according to my testing. This patch is the forward-port of RHEL-5 version of the patch.

[libvirt] How can I improve the performance of libvirt when running many virtual machines on same host
by Diego Dias 20 Jan '11

20 Jan '11

Hi, I am using Xen 4 as hypervisor and using libvirt 0.8.4 to communicate with it. When I run more than 35 virtual machines on the host, Libvirt starts to run extremely slow and I cant even execute a /"virsh list/". The memory usage of libvirtd is around 468288K. Is there any way to improve the performance of libvirt? Is there any maximum number of virtual machines libvirt can manage without having a poor performace? Best Regards, Diego Dias

[libvirt] virsh fails to define a domain

20 Jan '11

I am using the git version of libvirt. The domain file was working previously. [nikunj@dhruv ~]$ rpm -q qemu-kvm qemu-kvm-0.12.3-8.fc13.x86_64 Some more debugging suggested that qemuCapsExtractDeviceStr is returning an error. The output of the "pci-assign,?" is not returning any useful information on my system. [nikunj@dhruv ~]$ qemu-kvm -device "pci-assign,?" property "pci-assign.?" not found can't set property "?" to "on" for "pci-assign" [nikunj@dhruv ~]$ This is supposedly related to f892f5a562cbb6e5b914adced1000df20c3174d6 commit. Don't know what could be a valid fix for this tough. Regards Nikunj

[libvirt] [PATCH] qemu: Avoid sending STOPPED event twice
by Jiri Denemark 19 Jan '11

In some circumstances, libvirtd would issue two STOPPED events after it stopped a domain.

[libvirt] [PATCH 0/3] qemu: improve device capability detection
by Eric Blake 19 Jan '11

19 Jan '11

As promised in https://www.redhat.com/archives/libvir-list/2011-January/msg00562.html Patch 1 is complete, patch 2 can be pushed as-is, but if anyone has qemu-0.12.1 or qemu-kvm-0.12.3 handy (Fedora12 has 0.11.x, and Fedora13 has 0.12.5), then we can enhance it by filling in the contents of a couple more files. Patch 3 does not need to be pushed until the rest of my smartcard series is complete, but I'm including it now to show how to rewrite things in order to parse more device characteristics from a single qemu run, so it can be reused by the boot order patch series (add "-device","virtio-blk-pci,?" to extract; add strstr(str,"virtio-blk-pci.bootindex") to parse; and possibly update the qemuhelpdata/*-device files to include appropriate new lines to trigger the new flag detection).

[libvirt] [PATCH] Basic support for VDE networking
by Renzo Davoli 19 Jan '11

19 Jan '11

I have seen several messages asking for VDE networking support. There is an item also in your todo web page. http://libvirt.org/todo.html I have developed a patch to provide a basic support for VDE. It defines and manages the syntax: <domain ....> <device> <interface type='vde'> ... <switch path='/tmp/vde.ctl'/> </interface> </device> </domain> the switch tag can be omitted: vde uses the default switch. I have tested the qemu/kvm support. user-mode linux support is included but not tested yet. libvirt vde support for virtualbox has not been coded yet (virtualbox itself supports vde). The patch is against libvirt-0.8.7. renzo (designer/developer of VDE, university of bologna, wiki.virtualsquare.org) Signed-off-by: Renzo Davoli <renzo(a)cs.unibo.it> --- --- a/src/lxc/lxc_driver.c 2011-01-10 11:49:49.000000000 +0100 +++ b/src/lxc/lxc_driver.c 2011-01-10 11:50:03.000000000 +0100 @@ -1083,6 +1083,7 @@ case VIR_DOMAIN_NET_TYPE_INTERNAL: case VIR_DOMAIN_NET_TYPE_DIRECT: case VIR_DOMAIN_NET_TYPE_LAST: + case VIR_DOMAIN_NET_TYPE_VDE: break; } --- a/src/uml/uml_conf.c 2011-01-10 12:03:54.000000000 +0100 +++ b/src/uml/uml_conf.c 2011-01-10 13:26:08.000000000 +0100 @@ -269,6 +269,14 @@ virBufferVSprintf(&buf, "tuntap,%s", def->ifname); break; + case VIR_DOMAIN_NET_TYPE_VDE: + /* ethNNN=vde,vde_switch,macaddr,port,group,mode,description */ + if (def->data.vde.vdeswitch) { + virBufferVSprintf(&buf, "vde,%s", def->data.vde.vdeswitch); + } else + virBufferAddLit(&buf, "vde"); + break; + case VIR_DOMAIN_NET_TYPE_INTERNAL: umlReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("internal networking type not supported")); --- a/src/conf/domain_conf.h 2011-01-10 11:41:07.000000000 +0100 +++ b/src/conf/domain_conf.h 2011-01-10 13:21:08.000000000 +0100 @@ -288,6 +288,7 @@ VIR_DOMAIN_NET_TYPE_BRIDGE, VIR_DOMAIN_NET_TYPE_INTERNAL, VIR_DOMAIN_NET_TYPE_DIRECT, + VIR_DOMAIN_NET_TYPE_VDE, VIR_DOMAIN_NET_TYPE_LAST, }; @@ -336,6 +337,9 @@ int mode; virVirtualPortProfileParams virtPortProfile; } direct; + struct { + char *vdeswitch; + } vde; } data; char *ifname; virDomainDeviceInfo info; --- a/src/conf/domain_conf.c 2011-01-10 11:42:04.000000000 +0100 +++ b/src/conf/domain_conf.c 2011-01-10 14:49:46.000000000 +0100 @@ -182,7 +182,8 @@ "network", "bridge", "internal", - "direct") + "direct", + "vde") VIR_ENUM_IMPL(virDomainChrChannelTarget, VIR_DOMAIN_CHR_CHANNEL_TARGET_TYPE_LAST, @@ -598,6 +599,10 @@ VIR_FREE(def->data.direct.linkdev); break; + case VIR_DOMAIN_NET_TYPE_VDE: + VIR_FREE(def->data.vde.vdeswitch); + break; + case VIR_DOMAIN_NET_TYPE_USER: case VIR_DOMAIN_NET_TYPE_LAST: break; @@ -2293,6 +2298,7 @@ char *internal = NULL; char *devaddr = NULL; char *mode = NULL; + char *vdeswitch = NULL; virNWFilterHashTablePtr filterparams = NULL; virVirtualPortProfileParams virtPort; bool virtPortParsed = false; @@ -2379,7 +2385,11 @@ xmlStrEqual(cur->name, BAD_CAST "state")) { /* Legacy back-compat.

[libvirt] Installing libvirt 0.8.7 Ubuntu 9.10
by Marcela Castro León 19 Jan '11

19 Jan '11

Hello: I'm installing libvirt 0.8.7 on Ubuntu 9.10 to work at a project at Autonomous University. But when make ./configure, I've got: checking pkg-config is at least version 0.9.0... yes checking for XMLRPC... no checking for LIBXML... no checking libxml2 xml2-config >= 2.6.0 ... configure: error: Could not find libxml2 anywhere (see config.log for details). But I've libxml2 installed on mu system marcela@santacruz:~/libvirt/libvirt-0.8.7$ dpkg -l | grep libxml2 ii libxml2 2.7.5.dfsg-1ubuntu1.2 GNOME XML library ii libxml2-utils 2.7.5.dfsg-1ubuntu1.2 XML utilities ii python-libxml2 2.7.5.dfsg-1ubuntu1.2 Python bindings for the GNOME XML library The config.log mention No package 'libxml-2.0', but this libary doesn't exit. I've attach this log to further information. Can you tell me how to follow? Thank you.

[libvirt] Spice in libvirt 0.8.x?
by Justin Clift 18 Jan '11

Hi us, Does anyone know if Spice in libvirt 0.8.7 works ok? Noticed two BZ's (still open) by Amador Pahim (CC'd), where he tested with 0.8.6 and noticed problems with our XML vs reality (for him): https://bugzilla.redhat.com/show_bug.cgi?id=664190 https://bugzilla.redhat.com/show_bug.cgi?id=664192 He was able to get it working by commenting out two pieces of qemu_command.c, so I'm just wondering if this is useful info to us or if it's already dated? /* if ((def->videos[0]->type == VIR_DOMAIN_VIDEO_TYPE_QXL) && * !(qemuCmdFlags & QEMUD_CMD_FLAG_VGA_QXL)) { * qemuReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", * _("This QEMU does not support QXL graphics adapters")); * goto error; * } */ /* * if (def->graphics[0]->data.spice.listenAddr) * virBufferVSprintf(&opt, ",addr=%s", def->graphics[0]>data.spice.listenAddr); * else if (driver->spiceListen) * virBufferVSprintf(&opt, ",addr=%s", driver->spiceListen); */ + Justin

[libvirt] [PATCH] build: use more gnulib modules for simpler code
by Eric Blake 18 Jan '11

18 Jan '11

* .gnulib: Update to latest, for sigpipe and sigaction modules. * bootstrap.conf (gnulib_modules): Add siaction, sigpipe, strerror_r. * tools/virsh.c (vshSetupSignals) [!SIGPIPE]: Delete, now that gnulib guarantees it. (SA_SIGINFO): Define for mingw fallback. * src/util/virterror.c (virStrerror): Simplify, now that gnulib guarantees the POSIX interface. * configure.ac (AC_CHECK_FUNCS_ONCE): Drop redundant check.

[libvirt] [PATCH] Fix startup with VNC password expiry on old QEMU
by Daniel P. Berrange 18 Jan '11

[libvirt] Libvirt 0.8.7 installer ready for testing
by Justin Clift 18 Jan '11

18 Jan '11

Hi guys, Created the windows libvirt 0.8.7 installer using Matthias's updated scripting: http://libvirt.org/sources/win32_experimental/Libvirt-0.8.7-0.exe Does someone have time to test and confirm it's ok, before we point to it from the website? Arnaud, this version of the installer adds the virsh bin directory to the system PATH variable. So I'm thinking don't need to copy the libvirt dll's around, when using your C# bindings. If you've have time to test that, it would be great. Could then update the web page with that info. :) Regards and best wishes, Justin Clift

[libvirt] [PATCH] handle DNS over IPv6
by Paweł Krześniak 18 Jan '11

18 Jan '11

Firstly: Add ip6tables rules to allow DNS over IPv6 in network. Secondly: start dnsmasq with --interface option instead of --listen-address. Dnsmasq currently uses "--listen-address IPv4_address" option, which restricts DNS service to one IPv4 address only. We could append --listen-address for every IPv[46] address defined on interface, but it's cleaner to use "--interface brname". There were some problems in the past with --interface option. Dnsmasq version 2.46 and earlier exited with error when tired to bind() to IPv6 addresses on just brought up interfaces, because DAD (Duplicate Address Detection) takes some time to finish and bind() returns EADDRNOTAVAIL which caused dnsmasq to exit. Dnsmasq version 2.47 (released on 05-Feb-2009) fixed this issue by retrying bind() after getting EADDRNOTAVAIL error (as described in http://www.thekelleys.org.uk/dnsmasq/CHANGELOG; loop itself is defined in dnsmasq-2.47/src/network.c:404) * Using --interface option causes longer network startup: $ time virsh -c qemu:///system net-start isolated1 Network isolated1 started real 0m0.112s user 0m0.013s sys 0m0.009s $ time virsh -c qemu:///system net-start isolated1 Network isolated1 started real 0m2.101s user 0m0.011s sys 0m0.011s * Dnsmasq exits after DAD complets which guarantees that radvd will no more produces following warnings: Dec 28 19:42:11 nemo radvd[14652]: sendmsg: Invalid argument --- src/network/bridge_driver.c | 32 +++++++++++++++++++++++++------- 1 files changed, 25 insertions(+), 7 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 7d43ef5..a689c9f 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -469,16 +469,13 @@ networkBuildDnsmasqArgv(virNetworkObjPtr network, virCommandAddArgList(cmd, "--conf-file=", "", NULL); /* - * XXX does not actually work, due to some kind of - * race condition setting up ipv6 addresses on the - * interface.

[libvirt] [PATCH v2 0/4] Explicit boot device ordering
by Jiri Denemark 17 Jan '11

17 Jan '11

Currently, boot order can be specified per device class but there is no way to specify exact disk/NIC device to boot from. This patchset fixes that. There were two options suggested for how this should be modeled in domain XML: 1) <os> <boot target='net1'/> <boot target='net0'/> <boot target='hdc'/> <boot target='hdb'/> <os> Where target attributes would match /domain/devices/*/target@dev 2) Adding <boot order='n'/> elements into appropriate device elements. In addition to the two options Rich suggested a more compact variant of option 1. Per former discussion this patchset implements the second option. Version 2: - "qemu: Refactor qemuCapsParsePCIDeviceStrs using virCommand" dropped the rest was rebased on top of Eric's capabilities patches - added support for floppy devices which was forgotten in v1 Jiri Denemark (4): conf: Move boot parsing into a separate function Introduce per-device boot element qemu: Support per-device boot ordering tests: Add tests for per-device boot elements docs/formatcaps.html.in | 1 + docs/formatdomain.html.in | 41 +++++- docs/schemas/domain.rng | 20 +++- src/conf/capabilities.c | 3 +- src/conf/domain_conf.c | 148 ++++++++++++++------ src/conf/domain_conf.h | 2 + src/qemu/qemu_capabilities.c | 9 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 24 +++- src/qemu/qemu_command.h | 6 +- src/qemu/qemu_driver.c | 2 + src/qemu/qemu_hotplug.c | 8 +- .../qemuxml2argvdata/qemuxml2argv-boot-order.args | 1 + tests/qemuxml2argvdata/qemuxml2argv-boot-order.xml | 52 +++++++ tests/qemuxml2argvtest.c | 2 + tests/qemuxml2xmltest.c | 1 + 16 files changed, 265 insertions(+), 56 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-order.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-boot-order.xml -- 1.7.4.rc1

[libvirt] [PATCH] Simplify "NWFilterPool" to "NWFilter"
by Matthias Bolte 17 Jan '11

17 Jan '11

The public object is called NWFilter but the corresponding private object is called NWFilterPool. I don't see compelling reasons for this Pool suffix. One might argue that an NWFilter is a "pool" of rules, etc. Remove the Pool suffix from NWFilterPool.

[libvirt] website: API reference for virterror contains libvirt API also
by Matthias Bolte 17 Jan '11

17 Jan '11

The API reference website [1] for virterror contains the API reference for virterror as expected. But the complete libvirt API reference, that is already found at [2], is appended too. I looked into the XSLT process that generates those two HTML files from the libvirt-api.xml to understand why this happens, but I couldn't locate the problem.

[libvirt] [PATCH] tests: Remove obsolete secaatest
by Matthias Bolte 15 Jan '11

15 Jan '11

Before the security driver was refactored in d6623003 seclabeltest and secaatest were basically the same. seclabeltest was meant for SELinux and secaatest for AppArmor. Both tests exited early when the specific security driver backend wasn't enabled. With the new security manager trying to initialize a disabled security driver backend is an error that can't be distinguished from other errors anymore. Therefore, the updated seclabeltest just asks for the first available backend as this will always work even with SELinux and AppArmor backend being disabled due to the new Nop backend. Remove the obsolete secaatest and compile and run the seclabeltest unconditional. This fixes make check on systems that support AppArmor. --- tests/Makefile.am | 24 ------------------------ tests/secaatest.c | 45 --------------------------------------------- 2 files changed, 0 insertions(+), 69 deletions(-) delete mode 100644 tests/secaatest.c diff --git a/tests/Makefile.am b/tests/Makefile.am index 345cf46..72beb23 100644 --- a/tests/Makefile.am +++ b/tests/Makefile.am @@ -98,13 +98,7 @@ if WITH_VMX check_PROGRAMS += vmx2xmltest xml2vmxtest endif -if WITH_SECDRIVER_SELINUX check_PROGRAMS += seclabeltest -endif - -if WITH_SECDRIVER_APPARMOR -check_PROGRAMS += secaatest -endif if WITH_CIL check_PROGRAMS += object-locking @@ -191,13 +185,7 @@ if WITH_VMX TESTS += vmx2xmltest xml2vmxtest endif -if WITH_SECDRIVER_SELINUX TESTS += seclabeltest -endif - -if WITH_SECDRIVER_APPARMOR -TESTS += secaatest -endif if WITH_LIBVIRTD check_PROGRAMS += eventtest @@ -376,21 +364,9 @@ commandhelper_SOURCES = \ commandhelper_CFLAGS = -Dabs_builddir="\"`pwd`\"" commandhelper_LDADD = $(LDADDS) -if WITH_SECDRIVER_SELINUX seclabeltest_SOURCES = \ seclabeltest.c seclabeltest_LDADD = ../src/libvirt_driver_security.la $(LDADDS) -else -EXTRA_DIST += seclabeltest.c -endif - -if WITH_SECDRIVER_APPARMOR -secaatest_SOURCES = \ - secaatest.c -secaatest_LDADD = ../src/libvirt_driver_security.la $(LDADDS) -else -EXTRA_DIST += secaatest.c -endif qparamtest_SOURCES = \ qparamtest.c testutils.h testutils.c diff --git a/tests/secaatest.c b/tests/secaatest.c deleted file mode 100644 index d9d6b4a..0000000 --- a/tests/secaatest.c +++ /dev/null @@ -1,45 +0,0 @@ -#include <config.h> - -#include <unistd.h> -#include <stdlib.h> -#include <stdio.h> -#include <string.h> -#include <errno.h> -#include "security/security_driver.h" - -int -main (int argc ATTRIBUTE_UNUSED, char **argv ATTRIBUTE_UNUSED) -{ - int ret; - - const char *doi, *model; - virSecurityDriverPtr security_drv; - - ret = virSecurityDriverStartup (&security_drv, "apparmor", false); - if (ret == -1) - { - fprintf (stderr, "Failed to start security driver"); - exit (-1); - } - /* No security driver wanted to be enabled: just return */ - if (ret == -2) - return 0; - - model = virSecurityDriverGetModel (security_drv); - if (!model) - { - fprintf (stderr, "Failed to copy secModel model: %s", - strerror (errno)); - exit (-1); - } - - doi = virSecurityDriverGetDOI (security_drv); - if (!doi) - { - fprintf (stderr, "Failed to copy secModel DOI: %s", - strerror (errno)); - exit (-1); - } - - return 0; -} -- 1.7.0.4

[libvirt] [PATCHv2] Enable tuning of qemu network tap device "sndbuf" size
by Laine Stump 14 Jan '11

14 Jan '11

This is in response to a request in: https://bugzilla.redhat.com/show_bug.cgi?id=665293 In short, under heavy load, it's possible for qemu's networking to lock up due to the tap device's default 1MB sndbuf being inadequate. adding "sndbuf=0" to the qemu commandline -netdevice option will alleviate this problem (sndbuf=0 actually sets it to 0xffffffff). Because we must be able to explicitly specify "0" as a value, the standard practice of "0 means not specified" won't work here. Instead, virDomainNetDef also has a sndbuf_specified, which defaults to 0, but is set to 1 if some value was given. The sndbuf value is put inside a <tune> element of each <interface> in the domain. The intent is that further tunable settings will also be placed inside this element. <interface type='network'> ... <tune> <sndbuf>0</sndbuf> ... </tune> </interface> --- Changes from V1: sndbuf_specified is now a bool rather than an int bitfield. sndbuf is now unsigned long.

[libvirt] [PATCH 0/2] Update qemu password support (v2)
by Marc-André Lureau 14 Jan '11

14 Jan '11

Recently, QEMU learned set_password and expire_password monitor commands. http://qemu.com/qemu.git/commit/?id=7572150c189c6553c2448334116ab717680de66d The following patches make use of these new commands if available, and fallback on VNC-only password support. Change since v1: - moved qemuInitGraphicsPasswords to qemu_hotplug, renamed to qemuDomainChangeGraphicsPasswords. - updated what looks like a typo (that appears to work anyway) in initial patch from Daniel: - ret = qemuInitGraphicsPasswords(driver, vm, - VIR_DOMAIN_GRAPHICS_TYPE_SPICE, - &vm->def->graphics[0]->data.vnc.auth, - driver->vncPassword); + ret = qemuInitGraphicsPasswords(driver, vm, + VIR_DOMAIN_GRAPHICS_TYPE_SPICE, + &vm->def->graphics[0]->data.spice.auth, + driver->spicePassword); Marc-André Lureau (2): qemu: add set_password and expire_password monitor commands Use the new set_password monitor command to set password. src/qemu/qemu_driver.c | 22 ++++---- src/qemu/qemu_hotplug.c | 114 +++++++++++++++++++++++++++++++++++++++--- src/qemu/qemu_hotplug.h | 5 ++ src/qemu/qemu_monitor.c | 77 ++++++++++++++++++++++++++++ src/qemu/qemu_monitor.h | 7 +++ src/qemu/qemu_monitor_json.c | 56 ++++++++++++++++++++ src/qemu/qemu_monitor_json.h | 7 +++ src/qemu/qemu_monitor_text.c | 69 +++++++++++++++++++++++++ src/qemu/qemu_monitor_text.h | 7 +++ 9 files changed, 346 insertions(+), 18 deletions(-) -- 1.7.3.4

[libvirt] [PATCHv2] Add XML config switch to enable/disable vhost-net support
by Laine Stump 14 Jan '11

14 Jan '11

This patch is in response to https://bugzilla.redhat.com/show_bug.cgi?id=643050 The existing libvirt support for the vhost-net backend to the virtio network driver happens automatically - if the vhost-net device is available, it is always enabled, otherwise the standard userland virtio backend is used. This patch makes it possible to force whether or not vhost-net is used with a bit of XML. Adding a <driver> element to the interface XML, eg: <interface type="network"> <model type="virtio"/> <driver name="vhost"/> will force use of vhost-net (if it's not available, the domain will fail to start). if driver name="qemu", vhost-net will not be used even if it is available. If there is no <driver name='xxx'/> in the config, libvirt will revert to the pre-existing automatic behavior - use vhost-net if it's available, and userland backend if vhost-net isn't available. --- Changes from V1: enum now starts at 0 instead of -1. I just disallow "default" when parsing. This eliminates the need for vhost_specified.

I've tested sending 'hap=' to a Xen 3.2 machine without support for hap setting and verified that xend silently drops the unrecognized setting. --- src/xen/xm_internal.c | 9 +++++---- 1 files changed, 5 insertions(+), 4 deletions(-) diff --git a/src/xen/xm_internal.c b/src/xen/xm_internal.c index ec618aa..bfb6698 100644 --- a/src/xen/xm_internal.c +++ b/src/xen/xm_internal.c @@ -2413,10 +2413,11 @@ virConfPtr xenXMDomainConfigFormat(virConnectPtr conn, (1 << VIR_DOMAIN_FEATURE_APIC)) ? 1 : 0) < 0) goto no_memory; - if (xenXMConfigSetInt(conf, "hap", - (def->features & - (1 << VIR_DOMAIN_FEATURE_HAP)) ? 1 : 0) < 0) - goto no_memory; + if (priv->xendConfigVersion >= 3) + if (xenXMConfigSetInt(conf, "hap", + (def->features & + (1 << VIR_DOMAIN_FEATURE_HAP)) ? 1 : 0) < 0) + goto no_memory; if (def->clock.offset == VIR_DOMAIN_CLOCK_OFFSET_LOCALTIME) { if (def->clock.data.timezone) { -- 1.7.3.1

[libvirt] [PATCH] Enable tuning of qemu network tap device "sndbuf" size
by Laine Stump 14 Jan '11

14 Jan '11

This is in response to a request in: https://bugzilla.redhat.com/show_bug.cgi?id=665293 In short, under heavy load, it's possible for qemu's networking to lock up due to the tap device's default 1MB sndbuf being inadequate. adding "sndbuf=0" to the qemu commandline -netdevice option will alleviate this problem (sndbuf=0 actually sets it to 0xffffffff). Because we must be able to explicitly specify "0" as a value, the standard practice of "0 means not specified" won't work here. Instead, virDomainNetDef also has a sndbuf_specified, which defaults to 0, but is set to 1 if some value was given. The sndbuf value is put inside a <tune> element of each <interface> in the domain. The intent is that further tunable settings will also be placed inside this elemnent. <interface type='network'> ... <tune> <sndbuf>0</sndbuf> ... </tune> </interface> --- Note that in qemuBuildHostNetStr() I have moved if (vhostfd && *vhostfd) { virBufferVSprintf(&buf, ",vhost=on,vhostfd=%s", vhostfd); into a newly created "if (is_tap) { ... }" block. This always should have been inside such a conditional, but none existed until now. (I can make this a separate patch if anyone wants, but it seemed so simple and obvious that I took the slothenly way out :-) Also, as with the vhost patch, I didn't get the html docs updated for this addition either. I will add both in a single followup patch next week. docs/schemas/domain.rng | 10 ++++++++++ src/conf/domain_conf.c | 31 +++++++++++++++++++++++++++++-- src/conf/domain_conf.h | 4 ++++ src/qemu/qemu_command.c | 19 +++++++++++++++++-- 4 files changed, 60 insertions(+), 4 deletions(-) diff --git a/docs/schemas/domain.rng b/docs/schemas/domain.rng index 6d0654d..e2883aa 100644 --- a/docs/schemas/domain.rng +++ b/docs/schemas/domain.rng @@ -1025,6 +1025,16 @@ <ref name="filterref-node-attributes"/> </element> </optional> + <optional> + <element name="tune"> + <optional> +  + <element name="sndbuf"> + <ref name="unsignedInt"/> + </element> + </optional> + </element> + </optional> </interleave> </define> <define name="virtualPortProfile"> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 04ed502..5d1b8cf 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -2280,6 +2280,7 @@ err_exit: static virDomainNetDefPtr virDomainNetDefParseXML(virCapsPtr caps, xmlNodePtr node, + xmlXPathContextPtr ctxt, int flags ATTRIBUTE_UNUSED) { virDomainNetDefPtr def;

[libvirt] [PATCH 0/4] Add HAP to domain features
by Jim Fehlig 14 Jan '11

14 Jan '11

Hardware features such as Extended Page Table and Nested Page Table augment hypervisor software techniques such as shadow page table. Adding HAP (hardware assisted paging) to the virDomainFeature enumeration allows users to select between hardware and software memory management mechanisms for their guests. I've seen reports [1] of users asking for this capability in the past. Patch 3 is an attempt to advertise the feature in hvm guest capabilities for the Xen hypervisor. I have not found a way to discover the presence of HAP support through the xen tools. Instead, the feature is only advertised on Xen >= 3.3, which sadly won't accommodate distro backports to older Xen versions. Thanks for your comments, Jim [1] http://www.mail-archive.com/fedora-xen@redhat.com/msg02680.html Jim Fehlig (4): Add HAP to virDomainFeature enum Add support for HAP feature to xen drivers Add HAP to xen hypervisor capabilities Document HAP domain feature docs/formatdomain.html.in | 5 +++++ docs/schemas/domain.rng | 7 ++++++- src/conf/domain_conf.c | 3 ++- src/conf/domain_conf.h | 1 + src/xen/xen_hypervisor.c | 10 ++++++++++ src/xen/xend_internal.c | 4 ++++ src/xen/xm_internal.c | 8 ++++++++ src/xenapi/xenapi_driver.c | 2 ++ src/xenapi/xenapi_utils.c | 2 ++ 9 files changed, 40 insertions(+), 2 deletions(-) -- 1.7.3.1

[libvirt] virsh setmem and setmaxmem: which XML do they match?
by Justin Clift 14 Jan '11

14 Jan '11

Hi all, Updating the man pages for the virsh setmem and setmaxmem commands at the moment. These two commands only run on active guest domains. So, as a helpful pointer on how to make the change with an inactive domain, I'm going to mention what the equivalent XML tag is for use with virsh edit. Like this: Note, this command only works on active guest domains. To change the memory allocation for an inactive guest domain, use the virsh B<edit> command to update the XML <memory> element. I'm just not sure which XML element the setmem and setmaxmem commands map to. Does "setmaxmem" map to <memory>, and "setmem" map to <currentMemory>? The description in our XML format domain doc is less than clear. :/ Regards and best wishes, Justin Clift
