[libvirt] fc12 virsh tap device problem
by Chiradeep Vittal 10 Dec '09

10 Dec '09

Hi, On a fresh FC12 system, I am able to create and run KVM-based vms with tap networking using the qemu-kvm command line but not using virsh. I have user and group set to "root" in /etc/libvirt/qemu.conf. "user mode networking" works with virsh, but not tap! I have this xml: <domain type='kvm'> <name>centos</name> <uuid>22d9d573-d82c-c18d-36c0-d3ffef057468</uuid> <memory>131072</memory> <vcpu>1</vcpu> <os> <type arch='x86_64'>hvm</type> </os> <features> <acpi/> <pae/> </features> <clock offset='utc'/> <devices> <emulator>/usr/bin/qemu-kvm</emulator> <disk type='file' device='disk'> <source file='/var/lib/images/centos.5-4.x86-64/centos-small.img'/> <target dev='hda' bus='ide'/> </disk> <interface type='user'> <mac address='52:54:00:7e:5b:58'/> </interface> <interface type='ethernet'> <mac address='52:54:00:2e:33:c8'/> <script path='/var/lib/images/centos.5-4.x86-64/qemu-ifup'/> </interface> <graphics type='vnc' port='5910' autoport='no' listen=''/> </devices> </domain> This won't start even when I execute virsh as root: [root@fc12 centos.5-4.x86-64]# virsh -c qemu+unix:///system create domr.xml error: Failed to create domain from domr.xml error: monitor socket did not show up.: No such file or directory [root@fc12 centos.5-4.x86-64]# tail -3 /var/log/libvirt/qemu/centos.log LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-kvm -S -M pc-0.11 -m 128 -smp 1 -name centos -uuid 22d9d573-d82c-c18d-36c0-d3ffef057468 -monitor unix:/var/lib/libvirt/qemu/centos.monitor,server,nowait -boot c -drive file=/var/lib/images/centos.5-4.x86-64/centos-small.img,if=ide,index=0,boot=on -net nic,macaddr=52:54:00:7e:5b:58,vlan=0,name=nic.0 -net user,vlan=0,name=user.0 -net nic,macaddr=52:54:00:2e:33:c8,vlan=1,name=nic.1 -net tap,script=/var/lib/images/centos.5-4.x86-64/qemu-ifup,vlan=1,name=tap.0 -serial none -parallel none -usb -vnc :10 -vga cirrus warning: could not configure /dev/net/tun: no virtual network emulation qemu: Could not initialize device 'tap' '***** But I can execute the same command line and it works!!******** [root@fc12 centos.5-4.x86-64]# LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-kvm -S -M pc-0.11 -m 128 -smp 1 -name centos -uuid 22d9d573-d82c-c18d-36c0-d3ffef057468 -monitor unix:/var/lib/libvirt/qemu/centos.monitor,server,nowait -boot c -drive file=/var/lib/images/centos.5-4.x86-64/centos-small.img,if=ide,index=0,boot=on -net nic,macaddr=52:54:00:7e:5b:58,vlan=0,name=nic.0 -net user,vlan=0,name=user.0 -net nic,macaddr=52:54:00:2e:33:c8,vlan=1,name=nic.1 -net tap,script=/var/lib/images/centos.5-4.x86-64/qemu-ifup,vlan=1,name=tap.0 -serial none -parallel none -usb -vnc :10 -vga cirrus & [2] 4543 [root@fc12 centos.5-4.x86-64]# ps -ef | grep qemu root 4543 3449 0 19:02 pts/12 00:00:00 /usr/bin/qemu-kvm -S -M pc-0.11 -m 128 -smp 1 -name centos -uuid 22d9d573-d82c-c18d-36c0-d3ffef057468 -monitor unix:/var/lib/libvirt/qemu/centos.monitor,server,nowait -boot c -drive file=/var/lib/images/centos.5-4.x86-64/centos-small.img,if=ide,index=0,boot=on -net nic,macaddr=52:54:00:7e:5b:58,vlan=0,name=nic.0 -net user,vlan=0,name=user.0 -net nic,macaddr=52:54:00:2e:33:c8,vlan=1,name=nic.1 -net tap,script=/var/lib/images/centos.5-4.x86-64/qemu-ifup,vlan=1,name=tap.0 -serial none -parallel none -usb -vnc :10 -vga cirrus

[libvirt] qemu smbios options in domain xml format
by Phillip Balli 10 Dec '09

10 Dec '09

Hello, I could not find any explicit mention of support for the -smbios options which are present in qemu 0.10.5+ in the domain xml format or the qemu/kvm hypervisor driver pages. Is there some way to specify commands and options which are not described in the xml config by adjusting something in the way libvirt processes the xml? Or is providing smbios options just not supported currently?

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().

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

09 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

[libvirt] [PATCH] Use AM_PATH_PYTHON and python-config to detect Python configuration
by Matthias Bolte 09 Dec '09

09 Dec '09

Using AM_PATH_PYTHON solves the site-packages directory problem. 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 08 Dec '09

08 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 08 Dec '09

08 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 08 Dec '09

08 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 08 Dec '09

08 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] [PATCH] udev_device_get_devpath might return NULL
by Guido Günther 08 Dec '09

Fix crash on daemon strdup in that case. udev_device_get_devpath returs NULL for '/sys/devices/virtual/block/dm-*' devices. In that case the later strdup segfaults.
