I'd recommend giving virt-manager > 0.8.1 a shot, and report back here if you still hit virt-manager errors. > I installed the virt-manager-0.8.1 and virtinst-0.500.1. And the error was fixed. The virt-manager gui can works. Thank you! At the same time, i still can't create vm with the virt-manager-0.8.1 the error as below: Unable to complete install 'libvirt.libvirtError internal error Domain as didn't show up Traceback (most recent call last): File "/usr/local/dvirt/share/virt-manager/virtManager/create.py", line 1429, in do_install dom = guest.start_install(False, meter = meter) File "/usr/lib/python2.4/site-packages/virtinst/Guest.py", line 660, in start_install return self._do_install(consolecb, meter, removeOld, wait) File "/usr/lib/python2.4/site-packages/virtinst/Guest.py", line 758, in _do_install self.domain = self.conn.createLinux(install_xml, 0) File "/usr/lib/python2.4/site-packages/libvirt.py", line 974, in createLinux if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self) libvirtError: internal error Domain as didn't show up And the reason is as Daniel P. Berrange said, "'ia64' is not listed as a valid architecture in qemu_conf.c, RHEL-5 KVM only supports x86_64". In other words, the libvirt didn't support KVM emulator running on ia64 architecture. Thank you for your work on virt-manager. -dustin _________________________________________________________________ Keep your friends updated―even when you’re not signed in. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/so…

[libvirt] [PATCH] Add virBufferFreeAndReset() and replace free()
by Matthias Bolte 10 Dec '09

10 Dec '09

Replace free(virBufferContentAndReset()) with virBufferFreeAndReset(). Update documentation and replace all remaining calls to free() with calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset() and virReportOOMError() in OOM error cases. --- HACKING | 5 ++- daemon/libvirtd.c | 6 ++-- docs/hacking.html.in | 7 ++-- src/conf/capabilities.c | 4 ++- src/conf/domain_conf.c | 11 +++--- src/conf/interface_conf.c | 5 +-- src/conf/network_conf.c | 4 +-- src/conf/node_device_conf.c | 4 +-- src/conf/secret_conf.c | 4 +-- src/conf/storage_conf.c | 8 ++--- src/esx/esx_driver.c | 3 ++ src/esx/esx_vi.c | 10 ++--- src/esx/esx_vi_methods.c | 68 +++++++++--------------------------- src/esx/esx_vmx.c | 11 +----- src/libvirt_private.syms | 1 + src/node_device/node_device_udev.c | 1 + src/opennebula/one_conf.c | 3 +- src/openvz/openvz_conf.c | 8 +++-- src/openvz/openvz_driver.c | 3 +- src/phyp/phyp_driver.c | 5 +-- src/qemu/qemu_conf.c | 39 ++++++++++++++------- src/qemu/qemu_driver.c | 5 ++- src/security/virt-aa-helper.c | 9 +++-- src/storage/storage_backend.c | 3 +- src/uml/uml_conf.c | 4 +-- src/util/buf.c | 13 +++++++ src/util/buf.h | 1 + src/util/conf.c | 5 ++- src/util/logging.c | 8 +++- src/util/qparams.c | 1 + src/xen/xend_internal.c | 14 +++++--- src/xen/xm_internal.c | 19 +++++----- tools/virsh.c | 4 +- 33 files changed, 146 insertions(+), 150 deletions(-) diff --git a/HACKING b/HACKING index 548e2a0..3fb1113 100644 --- a/HACKING +++ b/HACKING @@ -293,10 +293,11 @@ eg typical usage is as follows: ... virBufferAddLit(&buf, "</domain>\n");

[libvirt] [RFC] virDomain{Attach,Detach}Device
by Jim Fehlig 10 Dec '09

10 Dec '09

History I found that virDomainDetachDevice did not work with inactive domains and submitted a patch [1] to fix this. As it turns out, some drivers do not support attaching/detaching devices on inactive domains and it was preferred that virDomain{Attach,Detach}Device only be permitted on active domains. I posted a follow-up patch [2] that restricted virDomain{Attach,Detach}Device to active domains only, although as Daniel Veillard pointed out this restriction should have been enforced in the libvirt front-end. Cole Robinson suggested improving virsh [3] to handle the case of inactive vs. active by redefining the domain with new device (or removed device) when domain is inactive. While implementing this improvement I asked some questions on IRC that resulted in another approach suggested by Dan Berrange as outlined below. Introduce two new APIs virDomainAttachDeviceFlags(virDomainPtr dom, const char *xml, unsigned flags) virDomainDetachDeviceFlags(virDomainPtr dom, const char *xml, unsigned flags) with flags being one or more from VIR_DOMAIN_DEVICE_ATTACH_CURRENT, VIR_DOMAIN_DEVICE_ATTACH_LIVE, VIR_DOMAIN_DEVICE_ATTACH_CONFIG. (I'm not sure about the ATTACH in these names. Perhaps CHANGE or MODIFY would be more appropriate.) If caller specifies CURRENT (default), add or remove the device depending on the current state of domain. E.g. if domain is active add or remove the device to/from live domain, if it is inactive change the persistent config. If caller specifies LIVE, only change the active domain. If caller specifies CONFIG, only change persistent config - even if the domain is active. If caller specifies both LIVE and CONFIG, then change both. If a driver could not satisfy the exact requested flags it must return an error. E.g if user specified LIVE but the driver can only change live and persisted config, the driver must fail the request. The existing virDomain{Attach,Detach}Device would be declared to be equivalent to virDomain{Attach,Detach}DeviceFlags(LIVE). Finally, virsh {attach,detach}-{disk,interface,device} would be modified to add a --persistent flag in order to set the appropriate flags when calling the new APIs.

[libvirt] [PATCH] Make QEMU text monitor parsing more robust
by Daniel P. Berrange 09 Dec '09

09 Dec '09

The QEMU 0.10.0 release (and possibly other 0.10.x) has a bug where it sometimes/often forgets to display the initial monitor greeting line, soley printing a (qemu). This in turn confuses the text console parsing because it has a '(qemu)' it is not expecting. The confusion results in a negative malloc. Bad things follow. This re-writes the text console handling to be more robust. The key idea is that it should only look for a (qemu), once it has seen the original command echo'd back. This ensures it'll skip the bogus stray (qemu) with broken QEMUs. * src/qemu/qemu_monitor.c: Add some (disabled) debug code * src/qemu/qemu_monitor_text.c: Re-write way command replies are detected --- src/qemu/qemu_monitor.c | 28 +++++++++++ src/qemu/qemu_monitor_text.c | 102 +++++++++++++++++++++++++++-------------- 2 files changed, 95 insertions(+), 35 deletions(-) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index abb763c..103cf28 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -39,6 +39,8 @@ #define VIR_FROM_THIS VIR_FROM_QEMU +#define QEMU_DEBUG_RAW_IO 0 + struct _qemuMonitor { virMutex lock; virCond notify; @@ -163,6 +165,24 @@ char *qemuMonitorEscapeShell(const char *in) } +#if QEMU_DEBUG_RAW_IO +#include <c-ctype.h> +static char * qemuMonitorEscapeNonPrintable(const char *text) +{ + int i; + virBuffer buf = VIR_BUFFER_INITIALIZER; + for (i = 0 ; text[i] != '\0' ; i++) { + if (c_isprint(text[i]) || + text[i] == '\n' || + (text[i] == '\r' && text[i+1] == '\n')) + virBufferVSprintf(&buf,"%c", text[i]); + else + virBufferVSprintf(&buf, "0x%02x", text[i]); + } + return virBufferContentAndReset(&buf); +} +#endif + void qemuMonitorLock(qemuMonitorPtr mon) { virMutexLock(&mon->lock); @@ -282,7 +302,15 @@ qemuMonitorIOProcess(qemuMonitorPtr mon) if (mon->msg && mon->msg->txOffset == mon->msg->txLength) msg = mon->msg; +#if QEMU_DEBUG_RAW_IO + char *str1 = qemuMonitorEscapeNonPrintable(msg ? msg->txBuffer : ""); + char *str2 = qemuMonitorEscapeNonPrintable(mon->buffer); + VIR_ERROR("Process %d %p %p [[[[%s]]][[[%s]]]", (int)mon->bufferOffset, mon->msg, msg, str1, str2); + VIR_FREE(str1); + VIR_FREE(str2); +#else VIR_DEBUG("Process %d", (int)mon->bufferOffset); +#endif if (mon->json) len = qemuMonitorJSONIOProcess(mon, mon->buffer, mon->bufferOffset, diff --git a/src/qemu/qemu_monitor_text.c b/src/qemu/qemu_monitor_text.c index 0d5ad79..72cb2bb 100644 --- a/src/qemu/qemu_monitor_text.c +++ b/src/qemu/qemu_monitor_text.c @@ -94,46 +94,78 @@ int qemuMonitorTextIOProcess(qemuMonitorPtr mon ATTRIBUTE_UNUSED, /* Look for a non-zero reply followed by prompt */ if (msg && !msg->finished) { - const char *end; - - /* We might get a prompt for a password */ - end = strstr(data + used, PASSWORD_PROMPT); - if (end) { - VIR_DEBUG("Woooo passwowrd [%s]", data + used); - if (msg->passwordHandler) { - size_t consumed; - /* Try and handle the prompt */ - if (msg->passwordHandler(mon, msg, - data + used, - len - used, - msg->passwordOpaque) < 0) - return -1; + char *start = NULL; + char *end = NULL; + char *skip; - /* Skip over prompt now */ - consumed = (end + strlen(PASSWORD_PROMPT)) - - (data + used); - used += consumed; - } else { - errno = EACCES; - return -1; + /* If we're here, we've already sent the command.

Hi, while writing SharpLibVirt I ran into several problems with some functions: virDomainInterfaceStats ------------------------------------ It is not possible get any result, because of error "invalid argument in invalid path, 'user.0' is not a known interface". But inside LOG for this domain is "... -net user,vlan=0,name=user.0 ... " It is not possible get stats for nic.0 also. Tested on KVM hypervisor. virStoragePoolIsActive and virStoragePoolIsPersistent ------------------------------------------------------------------------------- Both cause crash of libvirt deamon. I dont know why. Tested on 0.7.4 and Qemu 0.11.0 Thanks for answer, Jaromír Červenka Official openSUSE community member Web: http://www.cervajz.com/ Jabber: cervajz(a)cervajz.com MSN: jara.cervenka(a)seznam.cz Tel.: +420 607 592 687 Alt. e-mails: jaromir.cervenka(a)opensuse.org, jaromir.cervenka(a)speel.cz

At least in Ubuntu with Python 2.6 and later site-packages is renamed to dist-packages and site-packages is not part of sys.path anymore. So installing the libvirt Python bindings to site-packages renders them unusable, because they can be imported from there without manually including site-packages into sys.path. AM_PATH_PYTHON detects the correct site-packages/dist-packages directory. python-config --includes gives the correct include path for the Python header files. The old probing code stays there as fallback mechanism. * configure.in: use AM_PATH_PYTHON and python-config * python/Makefile.am: remove -I because PYTHON_INCLUDES contains it now --- configure.in | 110 +++++++++++++++++++++++++--------------------------- python/Makefile.am | 2 +- 2 files changed, 54 insertions(+), 58 deletions(-) diff --git a/configure.in b/configure.in index f735bba..d6e5979 100644 --- a/configure.in +++ b/configure.in @@ -1414,75 +1414,71 @@ AC_ARG_WITH([python], PYTHON_VERSION= PYTHON_INCLUDES= -PYTHON_SITE_PACKAGES= -PYTHON_TESTS= pythondir= if test "$with_python" != "no" ; then if test -x "$with_python/bin/python" then - echo Found python in $with_python/bin/python + AC_MSG_NOTICE(Found python in $with_python/bin/python) PYTHON="$with_python/bin/python" + with_python=yes else - if test -x "$with_python" - then - echo Found python in $with_python - PYTHON="$with_python" - else - if test -x "$PYTHON" - then - echo Found python in environment PYTHON=$PYTHON - with_python=`$PYTHON -c "import sys; print sys.exec_prefix"` - else - AC_PATH_PROG([PYTHON], [python python2.6 python2.5 python2.4 python2.3 python2.2 python2.1 python2.0 python1.6 python1.5]) - fi - fi - fi - if test "$PYTHON" != "" - then - PYTHON_VERSION=`$PYTHON -c "import sys; print sys.version[[0:3]]"` - echo Found Python version $PYTHON_VERSION - fi - if test "$PYTHON_VERSION" != "" - then - if test -r $with_python/include/python$PYTHON_VERSION/Python.h -a \ - -d $with_python/lib/python$PYTHON_VERSION/site-packages - then - PYTHON_INCLUDES=$with_python/include/python$PYTHON_VERSION - PYTHON_SITE_PACKAGES=$libdir/python$PYTHON_VERSION/site-packages - else - if test -r $prefix/include/python$PYTHON_VERSION/Python.h - then - PYTHON_INCLUDES=$prefix/include/python$PYTHON_VERSION - PYTHON_SITE_PACKAGES=$libdir/python$PYTHON_VERSION/site-packages - else - if test -r /usr/include/python$PYTHON_VERSION/Python.h - then - PYTHON_INCLUDES=/usr/include/python$PYTHON_VERSION - PYTHON_SITE_PACKAGES=$libdir/python$PYTHON_VERSION/site-packages - else - echo could not find python$PYTHON_VERSION/Python.h - fi - fi - if test ! -d "$PYTHON_SITE_PACKAGES" - then - PYTHON_SITE_PACKAGES=`$PYTHON -c "from distutils import sysconfig; print sysconfig.get_python_lib()"` - fi - fi + if test -x "$with_python" + then + AC_MSG_NOTICE(Found python in $with_python) + PYTHON="$with_python" + with_python=yes + else + if test -x "$PYTHON" + then + AC_MSG_NOTICE(Found python in environment PYTHON=$PYTHON) + with_python=yes + fi + fi fi - if test "$with_python" != "yes" - then - pythondir='$(PYTHON_SITE_PACKAGES)' + + if test "$with_python" == "yes" ; then + AM_PATH_PYTHON(,, [:]) + + if test "$PYTHON" != : ; then + PYTHON_CONFIG="$PYTHON-config" + + if test -x "$PYTHON_CONFIG" + then + PYTHON_INCLUDES=`$PYTHON_CONFIG --includes` + else + if test -r $PYTHON_EXEC_PREFIX/include/python$PYTHON_VERSION/Python.h + then + PYTHON_INCLUDES=-I$PYTHON_EXEC_PREFIX/include/python$PYTHON_VERSION + else + if test -r $prefix/include/python$PYTHON_VERSION/Python.h + then + PYTHON_INCLUDES=-I$prefix/include/python$PYTHON_VERSION + else + if test -r /usr/include/python$PYTHON_VERSION/Python.h + then + PYTHON_INCLUDES=-I/usr/include/python$PYTHON_VERSION + else + AC_MSG_NOTICE([Could not find python$PYTHON_VERSION/Python.h, disabling bindings]) + with_python=no + fi + fi + fi + fi + else + AC_MSG_NOTICE([Could not find python interpreter, disabling bindings]) + with_python=no + fi else - pythondir='$(libdir)/python$(PYTHON_VERSION)/site-packages' + AC_MSG_NOTICE([Could not find python in $with_python, disabling bindings]) + with_python=no fi -else - PYTHON= fi -AM_CONDITIONAL([WITH_PYTHON], test "$PYTHON_INCLUDES" != "") -AC_SUBST([pythondir]) +AM_CONDITIONAL([WITH_PYTHON], [test "$with_python" = "yes"]) AC_SUBST([PYTHON_VERSION]) AC_SUBST([PYTHON_INCLUDES]) -AC_SUBST([PYTHON_SITE_PACKAGES]) +AC_SUBST([pythondir]) + + AC_MSG_CHECKING([whether this host is running a Xen kernel]) RUNNING_XEN= diff --git a/python/Makefile.am b/python/Makefile.am index cda6559..736631e 100644 --- a/python/Makefile.am +++ b/python/Makefile.am @@ -4,7 +4,7 @@ SUBDIRS= . tests INCLUDES = \ $(WARN_CFLAGS) \ - -I$(PYTHON_INCLUDES) \ + $(PYTHON_INCLUDES) \ -I$(top_srcdir)/include \ -I$(top_builddir)/include \ -I$(top_builddir)/$(subdir) -- 1.6.0.4

[libvirt] C# (Mono) bindings for libvirt - SharpLibVirt
by Jaromír Červenka 09 Dec '09

09 Dec '09

Hello, following the example of email Richard W.M. Jones (https://www.redhat.com/archives/libvir-list/2008-September/msg00283.html) I decided to write libvirt interface for Mono. Everything is implemented in one C# file, including in-line help (see http://download.cervajz.com/sharplibvirt.png) which is taken from API documentation. All functions wich are implemented were tested on KVM hypervisor. Everything revolves around a few objects. It is possible call libvirt functions directly thru static class SharpLibVirt.libvirt (SharpLibVirt. virterror) or use my "helpers objects" - SharpLibVirt.slvConnection, SharpLibVirt.slvDomain, SharpLibVirt.slvStoragePool, SharpLibVirt.slvStorageVol, etc... Current status of binding is: Version: 0.7.4 virConnect: 95% virDommain: 95% virEvent: 0% virInterface: 0% virNetwork: 0% (I am currently working on it) virNodeDevice: 0% virNode: 98% virSecret: 0% virStoragePool: 100% virStorageVol: 100% virStream: 0% Others: 100% ----- virterror: 100% In the future I will keep SharpLibVirt up to date by C headers.

[libvirt] [PATCH] Fix virDomainObj ref handling in QEMU driver
by Daniel P. Berrange 09 Dec '09

09 Dec '09

Since the monitor I/O is processed out of band from the main thread(s) invoking monitor commands, the virDomainObj may be deleted by the I/O thread. The qemuDomainObjBeginJob takes an extra reference to protect against final deletion, but this reference is released by the corresponding EndJob call. THus after the EndJob call it may not be valid to reference the virDomainObj any more. To allow callers to detect this, the EndJob call is changed to return the remaining reference count. * src/conf/domain_conf.c: Make virDomainObjUnref return the remaining reference count * src/qemu/qemu_driver.c: Avoid referencing virDomainObjPtr after qemuDomainObjEndJob if it has been deleted. --- src/conf/domain_conf.c | 6 +- src/qemu/qemu_driver.c | 133 +++++++++++++++++++++++++++++------------------- 2 files changed, 84 insertions(+), 55 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 21d509d..dca2e49 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -231,7 +231,7 @@ static void virDomainObjListDeallocator(void *payload, const char *name ATTRIBUT { virDomainObjPtr obj = payload;

[libvirt] Add vncdisplay to virsh list
by Дмитрий Ильин 09 Dec '09

09 Dec '09

I think adding vncdisplay to virsh list output will be very usefull. For example output could be like this: Id Name State Display ---------------------------------------------------- 1 test1 running :2 2 test2 running :5 3 test3 running :13 4 server1 running n/g 5 sdltest running sdl - test4 shut off off - test5 shut off off :n - vnc display number n/g - no graphics sdl - sdl output You can use "--display" to enable it command: virsh list --all --display Also I would like to see "--pretend" option in virt-install. Just generate xml and dump it to stdout without doing anything else.

[libvirt] [PATCH 0/3] fix migration of paused vms
by Paolo Bonzini 09 Dec '09

09 Dec '09

From: Paolo Bonzini <pbonzini(a)gnu.org> This is yet another try on fixing migration of paused vms. Since the driver-only solution didn't work out, I'm now fixing it directly in libvirt.c. The first two patches are the same as for the previous series. The first is a bugfix for failed migration for the QEMU driver; the second adds a "virsh migrate --suspend" option to leave the VM not running on the destination machine. As in the previous version of the patch, --suspend/VIR_MIGRATE_PAUSED is the bulk of implementing the new feature. I just query the domain state and, if it is paused, I implicitly add the VIR_MIGRATE_PAUSED flag to the migration. This is the third patch. I thought about transmitting the state in the end (since it works well if VIR_MIGRATE_PAUSED is passed only to MigrateFinish and not to MigratePerform), but I don't think it's a good idea to commit it now as it's basically untestable. It's in the fourth patch, but if you want it now and think the approach is sound, tell me and I'll test it more heavily.

[libvirt] [BUG] connection to vbox 3.1 fails
by Florian Vichot 08 Dec '09

08 Dec '09

Hello all, As confirmed on IRC by Matthias, when trying to open a connection of any sort (vbox:///session or vbox:///system) to the vbox driver with a VirtualBox 3.1 installed, the connection fails with: "internal error nsIEventQueue object is null" This is printed by line 726 in vbox_tmpl.c. This is with the 3.1 support patch commited earlier today. The driver with a VirtualBox version 3.0.8 or 3.0.12 works fine with that patch. Thanks, Florian

[libvirt] [PATCH 00/14] Introduce support for the JSON based QEMU monitor
by Daniel P. Berrange 08 Dec '09

08 Dec '09

This is an updated series fully implementing the new QEMU monitor protocol based on JSON instead of plain text. I previously posted a proof of concept here http://www.redhat.com/archives/libvir-list/2009-November/msg00098.html Since that time, the QEMU side is actually working, so I've been able todo a real impl for libvirt now & also test it. I threw out the JSON library code I used last time, since it turned out to be quite unreliable code. Instead I'm using YAJL which is a much nicer library & integrates with libvirt very nicely.

[libvirt] Synchronous commands block virsh?
by Matthew Richardson 07 Dec '09

07 Dec '09

I'm currently playing with libvirt on Ubuntu 9.10: Compiled against library: libvir 0.7.0 Using library: libvir 0.7.0 Using API: QEMU 0.7.0 Running hypervisor: QEMU 0.11.0 I've noticed that if I open virsh on a host and set a live migration going, then virsh doesn't return until the migration is complete. However, if I open a second virsh command, it too blocks on commands (e.g list), meaning that I can't perform any other operations against other domains until the initial migration is complete. Is this deliberate or accidental? Is there any way round this? Thanks, Matthew The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

[libvirt] [PATCH 0/2] Xen: Add support for interface model='netfront'
by Jiri Denemark 05 Dec '09

05 Dec '09

Xen HVM guests with PV drivers end up with two network interfaces for each configured interface. One of them being emulated by qemu and the other one paravirtual. As this might not be desirable, the attached patch provides a way for users to specify that only paravirtual network interface should be presented to the guest. The configuration was inspired by qemu/kvm driver, for which users can specify model='virtio' to use paravirtual network interface. The patch adds support for model='netfront' which results in type=netfront instead of type=ioemu (or nothing for newer xen versions) in guests native configuration. Xen's qemu ignores interfaces with type != ioemu and only paravirtual network device will be seen in the guest. Four possible configuration scenarios follow: - no model specified in domain's XML - libvirt will behave like before this change; it will set type=ioemu for HVM guests on xen host which is not newer than XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU - covered by existing tests - PV guest, any model - no functional change, model is passed as is (and ignored by the hypervisor) - covered by existing tests (e.g., *-net-e1000.*) - HVM guest, model=netfront - type is set to "netfront", model is not specified - covered by new *-net-netfront.* tests - HVM guest, model != netfront - type is set to "ioemu", model is passed as is - covered by new *-net-ioemu.* tests The fourth scenario feels like a regression for xen newer than XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU as users who had a model specified in their guest's configuration won't see a paravirtual interface in their guests any more. On the other hand, the reason for specifying a model is most likely the fact that they want to use such model which implies emulated interface. Users of older xen won't be affected at all as their xen provides paravirtual interface regardless of the type used. In previous version of this patch, I used "xenpv" instead of "netfront" as it looked more like kvm/qemu's virtio.

[libvirt] libvirtd crashes
by Shi Jin 04 Dec '09

04 Dec '09

Hi there, My libvirtd built from the latest git code keeps on crashing on all machines. I turned on debugging and this is the information I have in the log file before crashing: 14:31:50.828: debug : virEventUpdateHandleImpl:146 : Update handle w=110 e=12 14:31:50.828: debug : virEventInterruptLocked:662 : Interrupting 14:31:50.828: debug : qemuMonitorCommandWithHandler:271 : Receive command reply ret=-1 errno=104 0 bytes '(null)' 14:31:50.828: error : qemuMonitorCommandWithHandler:290 : cannot send monitor command 'info cpus': Connection reset by peer 14:31:50.828: error : qemuMonitorTextGetCPUInfo:436 : internal error cannot run monitor command to fetch CPU thread info I am not sure if there is any other information needed to help identify the problem. My building options are: ./autogen.sh --prefix=/usr --sysconfdir=/etc --localstatedir=/var --without-xen --with-qemu --with-qemu-user=oneadmin --with-qemu-group=oneadmin --without-uml --without-vbox --without-openvz --without-lxc Please help me here. I can accept the service failing queries from time to time since I have error handling written so that they can be re-tried. But a crashing libvirtd takes the whole thing down. Thanks a lot.

[libvirt] both libvirt 0.7.4 and latest git crashing
by Nikola Ciprich 04 Dec '09

04 Dec '09

Hi, few days ago, I've reported problem with libvirt getting stuck while saving kvm. Today, I tried latest git and it seems the problem is solved which is great. Unfortunately, there seems to be another problem (which I noticed even for 0.7.4 although haven't reported yet) is that libvirtd sometimes crashes. I'm not 100% sure which action causes it to crash as it's being executed by cluster resource manager, but the backtrace might help those familiar with it's internals.

[libvirt] Move esxVMX_IndexToDiskName to util.c
by Matthias Bolte 04 Dec '09

04 Dec '09

I needed the inverse function to virDiskNameToIndex() for the ESX driver and added it to esx_vmx.c. The pending VirtualBox 3.1 patch needs disk index to disk name mapping too. So I want to move esxVMX_IndexToDiskName() to util.c. esxVMX_IndexToDiskName() handles indices up to 701. This limit comes from a gap in the disk name to disk index mapping of virDiskNameToIndex(): sdzy -> 700 sdzz -> 701 sdaaa -> 728 sdaab -> 729 This line in virDiskNameToIndex() causes this gap: idx = (idx + i) * 26; It can be fixed by altering this line to: idx = (idx + (i < 1 ? 0 : 1)) * 26; But this change breaks compatibility for indices > 701. So, I made two patches for either option and ask you for comments. Matthias

[libvirt] About libvirt API Support event notification mechanism problem
by ajia 03 Dec '09

03 Dec '09

Dear Daniel, Recently, I am writing test plan about libvirt asynchronous event mechanism, refering to the following bugs from the bugzilla: spice/vnc: https://bugzilla.redhat.com/show_bug.cgi?id=515268 disk error: https://bugzilla.redhat.com/show_bug.cgi?id=515270 I know libvirt can communicate with qemu monitor by QMP at present, can I use libvirt API to test it now?libvirt-0.7.4-1is ok? In addition,In qemu monitor with rhel6(2.6.31-31.el6.x86_64),"notify" command is nonexistent (Fedora12 is existent),if current qemu can't support event notification mechanism in rhel6,from libvirt point of view,I don't clear libvirt how to get asyns event notification?so I don't know how to test it.and I see qemu monitor protocol being patched,I am not sure current QMP status. I would be most grateful for any response . thank you very much. Best Regards, Alex Jia

[libvirt] Re: virDomainCreate() response time
by Christopher Pyper 03 Dec '09

I am using xen with libvirt and I have very slow response times with calls to virDomainCreate(). It takes approximately 5-6 seconds to return. Other calls like virDomainReboot() or virtDomainShutdown() return immediately. Do you know what might be causing this, and how I might speed this up. Cheers.

[libvirt] Eventtest unit test failure
by Soren Hansen 01 Dec '09

01 Dec '09

Hi, guys. I've changed the libvirt package in Ubuntu to run the test suite with every build. However, on our build daemons, the eventtest unit test seems to almost[1] consistently fail. You can see an example build log here: http://launchpadlibrarian.net/36196282/buildlog_ubuntu-lucid-amd64.libvirt_… Does this look familiar to anyone? Any idea what might be causing this? FWIW, I cannot reproduce it locally, so it's likely environmental, but at this point, I don't really know where to begin to look.

[libvirt] how do I stop libvirt futzing with my network configuration?
by Nix 01 Dec '09

01 Dec '09

So I have an existing QEMU/KVM setup with networks connected to a bridge which is routed/forwarded to the host's other interfaces. I'm trying to switch to administering at least *some* of its VMs through libvirt (probably not all as I use QEMU snapshots extensively for some of them and libvirt doesn't support that yet, if ever). So libvirt has to be able to start guests connected to a particular host bridge, and give them appropriate IP addresses. I thought it was easy to teach libvirt about this: spindle:/etc/libvirt/qemu/networks# cat /etc/libvirt/qemu/networks/default.xml <network> <name>default</name> <uuid>ee573497-1d74-473b-a2cb-9916229209b8</uuid> <forward mode='route'/> <bridge name='vm-net' stp='on' delay='0' /> <ip address='192.168.20.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.20.1' end='192.168.20.254' /> </dhcp> </ip> </network> However, there appears to be no way to say 'this is what the network is already like'. That network is considered 'inactive' and can't be used by any guests, and if I try to make it active, I get this: virsh # net-start default error: Failed to start network default error: cannot create bridge 'vm-net': File exists Of course it bloody can't create that bridge: it's already there, has an IP address on the host, and has the host routing packets to it. There appears to be no option to allow libvirt to assign IPs on the host... ... should I fix that, 'net-start' tries to update iptables rules! How should I put this: I do not *not not* want libvirt pissing with the firewall in any way at all. If I want firewall rules, I'll create them. But there's no way to tell it 'hands off! This network is already active, don't try to *make* it active!' ... at least, there's none in the documentation, and there's none in the code that I can see. Or is there?

Or just add it to the VMs XML <interface type='bridge'> <mac address='52:54:00:4f:0a:76'/> <source bridge='br0'/> </interface> Works like a charm and there's certainly no configuration in libvirt for this interface, ie. nothing in /var/run/libvirt/network, and *nothing* set up in Virt Manager under "Host Details->Virtual networks You do need to make sure that you disable netfilter on the bridge or setup the appropriate iptables rules ( see http://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared…) > So as far as I can tell, if you don't want libvirt creating all your > bridges for you, you may as well give up hope of using virt-manager, or > start hacking all this stuff out of the source. > > I hoped I could use libvirt in conjunction with raw qemu.

[libvirt] [PATCH v2] Disk- and Controller Hotplug
by wolfgang.mauerer＠siemens.com 01 Dec '09

01 Dec '09

Hi, this is the second revision of a patch series to improve disk hotadd support for libvirt. It focuses on the qemu backend, but is naturally designed to be compatible with other backends as well. The objective is two-fold: 1.) Split off controller from disk handling. This is done by introducing a new domain element <controller> that is used to describe disk controllers. Support for hotplugging such controllers is added. Support to reference controllers by name is also included. 2.) <disk>s can now be associated with a specific controller; this is done by means of a <controller> subelemnt for disks. This patch addresses the questions that were raised during the review of the initial submission, massages the code by fixing some whitespace issues, gets static controller configurations to work, and adds documentation. Notice that in contrast to the first submission I did not include the patch that adds support for disk- and controller hot_remove_. Since the qemu codebase is still in bit of a flux wrt. the necessary patches required for this functionality, it will reappear some time later as a separate submission.

[libvirt] questions on build qemu driver with non-root
by Shi Jin 30 Nov '09

30 Nov '09

Hi there, I have been successful in building the latest libvirt code from the git repository. The options I used to build is ./autogen.sh --prefix=/usr --sysconfdir=/etc --localstatedir=/var --without-xen --with-qemu --with-qemu-user=oneadmin --with-qemu-group=oneadmin --without-uml --without-vbox --without-openvz --without-lxc Please note that I have specified qemu user and group to be non-root. So far the libvirtd service and virsh both seem to work fine but I have a few issues 1. Before running "virsh create", the image belongs to user oneadmin. During the run, it still does. But the as soon as I shutdown/destroy the instance, the image ownership changes to -rw-rw—— 1 root root I don't understand why. Is this a bug? 2. From the documentation at http://libvirt.org/drvqemu.html, the directories /var/run/libvirt/qemu/, /var/lib/libvirt/qemu/ and /var/cache/libvirt/qemu/ must all have their ownership set to oneadmin:oneadmin. However, mine are still set to root:root and it does not seem to affect the running of libvirt/qemu/kvm. For example, oneadmin@test2:~$ ls /var/run/libvirt/qemu -la total 8 drwxr-xr-x 2 root root 80 2009-11-27 13:22 . drwxr-xr-x 3 root root 100 2009-11-27 13:07 .. -rw------- 1 root root 4 2009-11-27 13:22 client.pid -rw------- 1 root root 1250 2009-11-27 13:22 client.xml 3. The libvirtd service still shows the warning message: warning : qemudStartup:904 : Unable to create cgroup for driver: No such device or address I read from earlier posts that the --without-lxc option should get rid of this message. Thank you for your help. -- Shi Jin, PhD

Hi all, I saw two sets of node device enumeration implementation in libvirt-0.7.4 source code: 1.libudev implementation 2.HAL-based implementation I want to know which kind is used in libvirt.if both are used, which kinds solution is better? in my opinion,their abstract layer is different,HAL-based implementation may be flexible, by contrast, libudev implementation may be with better performance.whether plan to merge them or reserve a kind of implementation? thank you very much.I would be most grateful for any response . Best Regards, Alex Jia

[libvirt] strange problem only if /usr/sbin/libvirtd is named
by Shi Jin 29 Nov '09

29 Nov '09

Hi there, I am having a very strange problem. I have built a git libvirt for our servers running ubuntu 9.10. The same built works on all servers but one, which gives error information: 21:08:58.827: error : qemudStartup:926 : unable to set ownership of '/var/lib/libvirt/qemu' to user 400:400: Operation not permitted 21:08:58.827: error : qemudStartup:932 : unable to set ownership of '/var/cache/libvirt/qemu' to 400:400: This is because I used the --with-qemu-user and --with-qemu-group options in building libvirt. After hours of debugging, I figured out the problem: as long as the service binary is not named /usr/sbin/libvirtd, I don't have the above errors. For example, I can rename the binary as /usr/sbin/libvirtd.1 or copy it to anywhere else and it works. I am wondering if there is anything so special about this /usr/sbin/libvirtd file name. Also, it is so strange that it works for all other almost identical servers but this particular one. I appreciate your help. -- Shi Jin, PhD

[libvirt] saving domains causes stucks all other commands
by Nikola Ciprich 29 Nov '09

29 Nov '09

Hi, I noticed that using libvirt to save running KVM domain (ie using virsh save ...) causes all other attempts to connect to libvirt and do something to hang till the save finishes. Seems like the issue has been already reported once: http://www.mail-archive.com/libvir-list@redhat.com/msg11431.html but without any resoulution.

[libvirt] Howto store schedinfo in the domain definition
by Ralf Nyren 27 Nov '09

Hi, Is there support for storing the values accessible with eg virsh schedinfo <domain> --set param=value in the domain definition xml file? Tried to find the syntax definition for this but didn't find anything. Many thanks, Ralf

[libvirt] Problem in handling fast prints from QEMU to stderr
by Saul Tamari 27 Nov '09

27 Nov '09

Hi, I think I spotted a bug in the way libvirtd handles stderr output from QEMU VMs. When starting a VM and QEMU outputs too much output data to stderr (during a given time period), libvirtd will fail and report the following error to /var/log/messages: libvirtd: 13:44:40.695: error : internal error Out of space while reading console log output I looked at the libvirt code a bit and it seems like the stderr-handling code (I think its in qemudReadLogOutput()) is time-dependent and if a 4K buffer overflows it will stop running this VM. As a workaround I added some usleep(250000) near the fprintf() calls (inside QEMU) and I now manage to get the VM running. Is this the way libvirtd is supposed to behave? Thanks, Saul p.s. This was tested on FC11 and libvirtd is version 0.6.2

[libvirt] [PATCH] Xen: Add support for interface model='xenpv'
by Jiri Denemark 26 Nov '09

26 Nov '09

Xen HVM guests with PV drivers end up with two network interfaces for each configured interface. One of them being emulated by qemu and the other one paravirtual. As this might not be desirable, the attached patch provides a way for users to specify that only paravirtual network interface should be presented to the guest. The configuration was inspired by qemu/kvm driver, for which users can specify model='virtio' to use paravirtual network interface. The patch adds support for model='xenpv' which results in type=xenpv instead of type=ioemu (or nothing for newer xen versions) in guests native configuration. Xen's qemu ignores interfaces with type != ioemu and only paravirtual network device will be seen in the guest. A possible addition to this would be to force type=ioemu for all other models which would result in only emulated network device to be provided for an HVM guest on xen newer then XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU. No type would be configured when model is missing in domains XML. If you think this is a good idea, I'll prepare a second version of the patch.

[libvirt] How do I import an old VM image to a new Install
by Michael N. Moran 26 Nov '09

26 Nov '09

First, I am a casual VM user. I have been using Fedora Core 7 on my Dell laptop for a couple of years with a single QEMU/KVM guest running Windoze XP. I recently installed Fedora 12 on a new hard disk and would like to use my old Windows VM image on the new install. Is there an easy way to do this? I tried copying the image itself (WindozeXpDisk.raw) to the new install and then (naively) looked for an import on the Virtual Machine Manager GUI. The closest that I found was the File->Restore saved machine. I tried that on my WindozeXpDisk.raw image and it failed as follows: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/manager.py", line 461, in restore_saved_callback newconn.restore(file_to_load) File "/usr/share/virt-manager/virtManager/connection.py", line 649, in restore self.vmm.restore(frm) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1420, in restore if ret == -1: raise libvirtError ('virDomainRestore() failed', conn=self) libvirtError: operation failed: image magic is incorrect I *can* mount the image using kpartx et. al like this; sudo kpartx -av /var/virt/WindozeXpDisk.raw add map loop1p1 (253:2): 0 31101777 linear /dev/loop1 63 sudo mount -t ntfs /dev/mapper/loop0p1 ./mnt Any clues would be helpful. thank you, mike

[libvirt] crash in libvirtd when assigning PCI device (storage controller)
by Terje Marthinussen 26 Nov '09

26 Nov '09

Compiled libvirt and friends from todays sources on ubuntu 9.10. Was playing around with vt-d and while my MB works fine with ESXi 4, I got some permission issues when I tried the KVM and virt-manager included from ubuntu so I just gambled and compiled everything from latest sources. Things seems to work fine in a normal use case, but if I a PCI device such as a storage controller, libvirtd will get a sigsev. I got the onboard Intel Sata, a PCI Sil Sata card as well as an Areca Raid controller in this machine. I have not tried the Intel Sata device as I am booting from that, but both the other devices causes sigsev. I am sure assigned an intel network card a bit earlier and it actually worked (well, the VM started to boot at least and entered win7 installation without libvirtd crashing), but when I tested that again now, seems like the ethernet card causes the same problem.

[libvirt] [PATCH 0/2] Add MAC filtering to qemu
by Gerhard Stenzel 24 Nov '09

24 Nov '09

The following series of patches is a prototype implementation of a ebtables based MAC address filter. I hope to have addressed all the previous comments. At the moment, some defaults are set when libvirtd starts and when a domain is started or destroyed. The plan is to extend this filter capability to the API level and virsh command level. The plan is also to add more filtering features like VLAN filtering and QoS filtering.

[libvirt] virt-manager and messages in /var/log/messages
by Chandru 23 Nov '09

23 Nov '09

Apologies if this has been already discussed. While using virt-manager to create a vm-guest we see the following errors being logged in /var/log/messages. libvirtd: 22:40:57.675: error : Domain not found: no domain with matching name 'guest1' libvirtd: 22:42:22.039: error : invalid storage volume pointer in no storage vol with matching path libvirtd: 22:44:55.530: error : Domain not found: no domain with matching uuid While these errors are indeed harmless and we are able to create and use a vm-guest, why log them as error messages. Could we convert them into informational messages. Though they could mean errors in other scenarios, but could we tweak or change them in a way that they could be logged in as informational messages and not as error messages. A end user would not know what to do with them. Thanks, Chandru

[libvirt] Release of libvirt-0.7.4
by Daniel Veillard 21 Nov '09

21 Nov '09

Nearly as expected, but the 0.7.3 release had a missing file and some broken dependancies, so I rolled out a new release immediately. Available as usual at ftp://libvirt.org/libvirt/ The rate of changes doesn't seems to slow down, though this release is more about incremental improvements, bug fixes and cleanups than major new features: Features: - Implement a node device backend using libudev (David Allan) - New APIs for checking some object properties (Daniel P.

[libvirt] [PATCH] 514532 Fix man page, most operation are synchronous
by Daniel Veillard 21 Nov '09

As pointed in https://bugzilla.redhat.com/show_bug.cgi?id=514532 we were historically warning about operation being asynchronous in the man page but actually most operations are synchronous. I still kept a warning about domain creation and shutdown, maybe we should add a few more, but as is this is mostly correct and better than the current description IMHO Maybe we should flag formally in the description all APIs which have an asynchronous behaviour. 514532 Fix man page, most operation are synchronous * tools/virsh.pod: the man page was stating that most operations are asynchronous while in fact most of them are synchronous except domain creation and shutdown diff --git a/tools/virsh.pod b/tools/virsh.pod index 55ec64a..2986c34 100644 --- a/tools/virsh.pod +++ b/tools/virsh.pod @@ -40,12 +40,11 @@ Most B<virsh> commands require root privileges to run due to the communications channels used to talk to the hypervisor.

[libvirt] PATCH: recent qemu-kvm requires -enable-kvm flag to activate VT optimization
by Steve Yarmie 21 Nov '09

21 Nov '09

Hello, Recent qemu releases require command option '-enable-qemu' in order for the kvm functionality be activated. Libvirt needs to pass this flag to qemu when starting a domain. Note that without the option, even if both the kernel and qemu support KVM, KVM will not be activated and VMs will be slow as molasses ;) I added a check in qemu_conf.c to see if `qemu -help` emits the -enable-kvm flag, and if so, use the flag accordingly. There exists a check in src/qemu/qemu_conf.c to check for the -no-kvm flag. This check works the same way. Adding the included code will not break systems where qemu does not have the option.

[libvirt] [PATCH] Removing devicePath member from dev struct
by Dave Allan 20 Nov '09

20 Nov '09

I realized that I inadvertently added a member to the def struct to contain each device's sysfs path when there was an existing member in the dev struct for "OS specific path to device metadat, eg sysfs" Since the udev backend needs to record the sysfs path while it's in the process of creating the device, before the dev struct gets allocated, I chose to remove the member from the dev struct. I've attached a patch. An alternative would be to store the information twice, but that seems crufty to me.

[libvirt] race between qemu monitor startup and blocking migrate -incoming
by Charles Duffy 19 Nov '09

19 Nov '09

Howdy, 'yall. I'm having issues with virDomainRestore failing, particularly under load -- even in 0.7.0, when there's no need to parse through qemu's output to find the monitor PTY. Digging through strace output of libvirtd and the qemu processes it spawns, this is happening when qemu blocks on the migrate -incoming and ceases to respond to the monitor socket -- though some versions of qemu can go into this state before the monitor socket is even opened, leading to libvirt timing out either while attempting to open the monitor socket or while trying to read therefrom, and subsequently killing the qemu instance it spawned while that instance is still attempting to migrate in its old saved state. Both of qemu-0.11.0-rc1 and qemu-kvm master have some form of blocking in -incoming exec: which can prevent libvirt from successfully carrying through a resume; I have reproduced the issue (and maintain logs from strace, available on request) irrespective of the state of Chris Lalancette's "Fix detached migration with exec" and "Allow monitor interaction when using migrate -exec" patches. The qemu binaries being used _appear_ to correctly allow monitor interaction prior to -incoming exec:... completion when interactively invoked in the trivial case shown below: $ qemu-system-x86_64 \ -monitor stdio \ -nographic \ -serial file:/dev/null \ -incoming 'exec:sleep 5; echo DONE >&2; kill $PPID' \ /dev/null QEMU 0.10.91 monitor - type 'help' for more information (qemu) DONE $ ...however, whether these same binaries work as-expected when invoked from libvirt by our automated test system under load is nondeterministic. (I have yet to reproduce the issue in a low-load environment using "virsh restore"). Is someone else working on this? Is a known-good (or believed-good) libvirt/qemu pair available? What can I do to help in getting this issue resolved? Thanks! --- libvirt-0.7.0 + qemu-kvm-0.11.0-rc1 qemudReadMonitorOutput:728 : internal error Timed out while reading monitor startup output libvirt-0.6.5 + qemu-kvm-0.11.0-rc1 error : qemudReadMonitorOutput:705 : internal error Timed out while reading monitor startup output error : qemudWaitForMonitor:1003 : internal error unable to start guest: char device redirected to /dev/pts/9 libvir: QEMU error : internal error unable to start guest: char device redirected to /dev/pts/9 ^^ particularly interesting, as the above line should have been eaten by qemudExtractMonitorPath rather than emitted as error text --- <aliguori> -incoming is blocking <aliguori> you cannot interact with the monitor during -incoming <mDuff> ...shouldn't we always be opening the monitor before starting the blocking -incoming bits, though?

[libvirt] iSCSI Multi-IQN (Libvirt Support)
by Shyam_Iyer＠Dell.com 19 Nov '09

19 Nov '09

The following patch set realizes the multi-IQN concept discussed in an earlier thread http://www.mail-archive.com/libvir-list@redhat.com/msg16706.html The patch realizes an XML schema like the one below and allows libvirt to read through it to create storage pools. These XMLs when created using a virtualization manager realize unique VM to storage LUN mappings through a single console and thus opening up possibilities for the following scenarios - * possibility of multiple IQNs for a single Guest * option for hypervisor's initiator to use these IQNs on behalf of the guest Example Usages: Usage 1: VM1 - > <Init iqn1> <------------------------> <Target iqn1> <Init iqn2> <------------------------> <Target iqn1> <Init iqn3> <------------------------> <Target iqn1> <Init iqn4> <------------------------> <Target iqn1> Usage 2: VM1 - > <Init iqn1> <------------------------> <Target iqn1> <Init iqn2> <------------------------> <Target iqn2> <Init iqn3> <------------------------> <Target iqn3> <Init iqn4> <------------------------> <Target iqn4> Usage 3: VM1 - > <Init iqn1> <------------------------> <Target iqn1> VM2 - > <Init iqn2> <------------------------> <Target iqn1> Usage 4: VM1 - > <Init iqn1> <------------------------> <Target iqn1> VM2 - > <Init iqn2> <------------------------> <Target iqn2> Example XML schema for an iSCSI storage pool created -- <pool type="iscsi"> <name>dell</name> <uuid>cf354733-b01b-8870-2040-94888640e24d</uuid> <capacity>0</capacity> <allocation>0</allocation> <available>0</available> - <source> <initiator> iqnname = "<initiator IQN1>"> iqnname = "<initiator IQN2>"> </initiator> ........................................ ........................................ <host name="<iSCSI target hostname or Target IP address>" /> <device path="<iSCSI Target IQN name>" /> </source> - <target> <path>/dev/disk/by-path</path> - <permissions> <mode>0700</mode> <owner>0</owner> <group>0</group> </permissions> </target> </pool> Each initiator iqn name can be parsed to create the unique sessions. TODO: 1) Virt Manager GUI support to allow a visual mapping of iqn->storage pool -> VM and thus creating the XML for consumption by libvirt. Libvirt support added above can realize the same using virsh options. 2) option for Guest's own BIOS & initiator to use the initiator IQNs (iSCSI in Guest) a) Libvirt support to allow iqn as an attribute for a VM's XML. b) Qemu Support to allow Guest's bios & initiator to use these IQNs.

Uri may specify the hostname or IP address of the destination host as seen from the source, or uri may be a URI giving transport, hostname, user, port, etc. in the usual form.

[libvirt] migration: qemu vs. qemu+tcp at virsh vs. libvirt-java
by Thomas Treutner 18 Nov '09

18 Nov '09

Hi, I'm having a little problem when triggering (live) migration from libvirt-java (libvirt.so at client is approx. 0.7.1), I get an error that the qemu:// driver for migration URIs is not supported, only qemu+tcp:// Strange thing is, with virsh at the same client (same libvirt.so), qemu:// works. Interestingly, the error message seems to come from libvirt.so and not libvirt-java. I'd like to avoid maintaining two different URIs/drivers for normal connections and migration destinations, especially as it works flawlessly (and fast!) with virsh? Has anyone clues where this twisted-mind behaviour could come from? kr, tom

It would be helpful to have an API that exposes the relationship between SR IOV physical functions (PFs) and virtual functions (VFs).

[libvirt] PATCH 0/2]: Fix CPU affinity management for NR_CPUS > 1024
by Daniel P. Berrange 18 Nov '09

18 Nov '09

The RHEL-6 Alpha kernels have defined NR_CPUS=4096 The glibc static cpu_set_t data type used with sched_[gs]etaffinity() has been sized with # define __CPU_SETSIZE 1024 So any attempt to use sched_[gs]etaffinity() with a static cpu_set_t on a RHEL-6 kernel ends up with -EINVAL, even if the machine does not physically have > 1024 CPUs. The syscall mandates that the cpu set arg is large enough to hold entire of NR_CPUS. Fairly recent gLibc's now provide an alternative dynamically allocated cpu_set_t data type, where the app tells glibc how many CPUs it has to be able to hold. Great, except, the kernel does not tell userspace what NR_CPUS it has been compiled with. So apps have to a pick a starting size, try the sched_[gs]etaffinity() call, catch EINVAL, enlarge the cpuset, repeat, repeat, repeat until it works. This was going to be horrible to put into the qemu driver code, so I've introduced a new util/processinfo.[h,c] file providing APis for getting/setting CPU affinity that use the dynamically allocate mask libvirt defines in its public API.

Best is just to consider it's not in the allowed values The problem is that the error won't be ouput since the xend driver will then be called and raise an error error: this function is not supported by the hypervisor: unsupported in xendConfigVersion < 4 which will override the useful information from xenUnifiedDomainSetSchedulerParameters() So best is to also invert the order in which the xen sub-drivers are called * src/xen/xen_hypervisor.c: mark 65535 cap value as out of bound * src/xen/xen_hypervisor.c: reverse the order of the calls to the xen sub drivers to get the error message if needed diff --git a/src/xen/xen_driver.c b/src/xen/xen_driver.c index 4bfcce4..a7da2ec 100644 --- a/src/xen/xen_driver.c +++ b/src/xen/xen_driver.c @@ -1524,7 +1524,8 @@ xenUnifiedDomainSetSchedulerParameters (virDomainPtr dom, GET_PRIVATE(dom->conn); int i, ret; - for (i = 0; i < XEN_UNIFIED_NR_DRIVERS; ++i) { + /* do the hypervisor call last to get better error */ + for (i = XEN_UNIFIED_NR_DRIVERS - 1; i >= 0; i--) { if (priv->opened[i] && drivers[i]->domainSetSchedulerParameters) { ret = drivers[i]->domainSetSchedulerParameters(dom, params, nparams); if (ret == 0) diff --git a/src/xen/xen_hypervisor.c b/src/xen/xen_hypervisor.c index 843102a..4254bcd 100644 --- a/src/xen/xen_hypervisor.c +++ b/src/xen/xen_hypervisor.c @@ -1345,8 +1345,8 @@ xenHypervisorSetSchedulerParameters(virDomainPtr domain, } else if (STREQ (params[i].field, str_cap) && params[i].type == VIR_DOMAIN_SCHED_FIELD_UINT) { val = params[i].value.ui; - if (val > USHRT_MAX) { - snprintf(buf, sizeof(buf), _("Credit scheduler cap parameter (%d) is out of range (0-65535)"), val); + if (val >= USHRT_MAX) { + snprintf(buf, sizeof(buf), _("Credit scheduler cap parameter (%d) is out of range (0-65534)"), val); virXenErrorFunc (domain->conn, VIR_ERR_INVALID_ARG, __FUNCTION__, buf, val); return(-1); } -- 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] vCenter behaviour
by Glenn Bailey 17 Nov '09

17 Nov '09

Howdy, I was taking a look at libvirt for controlling a couple of vCenter clusters and noticed it will only let you login directly to an ESX host and not the vCenter server itself. You can pass the "vcenter=" command but this seems to just tell what vcenter server to use and doesn't directly access it. If you do a "list" it still just lists the devices on the given ESX host. For a quick test I modified the esx_driver.c and added the following (I am no c programmer BTW): if (STRCASEEQ(conn->uri->scheme, "esx")) { if (priv->host->productVersion != esxVI_ProductVersion_VPX25 && priv->host->productVersion != esxVI_ProductVersion_VPX40 && priv->host->productVersion != esxVI_ProductVersion_ESX35 && priv->host->productVersion != esxVI_ProductVersion_ESX40) { Which would then let me connect directly to the vCenter server and list all the vm's on it. Am I missing something? I'm new to libvirt, but all management of a ESX cluster is always done through vCenter, and not the host. Sorry if this message is redundant as I didn't see anything blaring in the archives ;-) glenn terremark

[libvirt] ESXi: libvirt python bindings
by Federico Fortini 17 Nov '09

17 Nov '09

Hi to all. I was reading a recent post titled "ESX with Python binding", and tried to test the code posted by Matthias Bolte. I was wondering if ESXi should be considered different from ESX, because as soon as i tried to connect to esxi host I've got a traceback. The exception is raised from libvirt.py line 25 and is: libvirt.libvirtError: virConnectOpenAuth() failed Any tips to go on? My purpose is to write a simple python/django web app to "manage" esxi virtual machine. Tia, Federico Fortini

[libvirt] stat() vs. access()
by Maximilian Wilhelm 17 Nov '09

17 Nov '09

Hi! While discussing some code with Matthias, we stumbled across many occurances of stat() calls within the libVirt code (virFileExists() for example) which could be implemented in a cheaper way when using access() instead of stat(), when the only purpose is to check for the existance of a file. The one thing I'm concerned about, is the question if access() does the right thing in all situations. As the manpages didn't tell anything about directories it might be worth to clarify this in advance. A simple practical test showed that access ("/path/to/dir", F_OK) seems to work as expected. Any comments on these (optimization) thoughs? Ciao Matthias and Max -- Gib Dein Bestes. Dann übertriff Dich selbst!

[libvirt] Fedora MinGW - need for *.def files
by Richard W.M. Jones 17 Nov '09

17 Nov '09

[This is just a FYI ...] Upstream binutils or gcc changed the default way that symbols are exported for cross-compiled (Fedora MinGW) DLLs. Previously all symbols were exported. Now they are only exported if they are explicitly listed in a *.def file. There are two ways that libvirt could be changed to do the right thing here. Either (probably simplest) add '-export-all-symbols' to the libtool command line. This would have to be done conditionally based on Win32 being the compilation target. Or create a *.def file. It looks like: LIBRARY libvirt.dll DESCRIPTION "libvirt foo blah" EXPORTS <<list of symbol names, one per line>> http://msdn.microsoft.com/en-us/library/d91k01sh%28VS.80%29.aspx http://msdn.microsoft.com/en-us/library/28d6s79h%28VS.80%29.aspx The LIBRARY and DESCRIPTION lines are optional. You have to add '-export-symbols libvirt.def' to the libtool command line. (It's not clear to me at the moment if you only do this for Windows or if it's safe to pass this on all platforms -- the documentation for this is very sparse). There is a third method: you can munge all the code by adding __declspec(dllexport) to all exported symbols in the header files, conditionally of course. I'm pretty sure that's the worst of all worlds. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-top is 'top' for virtual machines.

I tried nesting VM's but the hw virt flags are not passed to the next level QEMU-CPU. What version is this going to be available so we have reasonable acceleration? -Gerry

[libvirt] [PATCH] only remove masquerade rules in NAT mode
by Guido Günther 16 Nov '09

16 Nov '09

Hi, attached patch makes sure we only remove the masquerade rules if forwardType == VIR_NETWORK_FORWARD_NAT and not if forwardType == VIR_NETWORK_FORWARD_ROUTE since we don't use them there. This fixes: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=549949 O.k. to apply? -- Guido

[libvirt] Security driver on el5
by Daniel Berteaud 16 Nov '09

16 Nov '09

Hi. I'm running libvirt (0.7.2) on a CentOS 5.4 host. It's working quite well, but only if I configure selinux in permissive mode. I've tried to build libvirt with selinux enabled, but no matter what I try, it's still disabled. After some searching, I've found that: http://article.gmane.org/gmane.comp.emulators.libvirt/12282 "- Added a configure.in check for selinux_virtual_domain_context_path() and selinux_virtual_image_context_path() and make it disable the SELinux driver if these aren't found. These functions are new on F11, so we don't want to break build on RHEL-5 & earlier Fedora." Does this means there's no way to get selinux security driver on el5 (or anything before fedora 11) ?
