[libvirt] Remote virConnect.listDomainsID() returns invalid IDs (Python, Xen)
by Russell Haering 14 May '09

14 May '09

I'm working with the Libvirt Python bindings and have discovered the following: If I run virConnect.listDomainsID() locally I get a list of valid IDs. For example: >>> import libvirt >>> conn = libvirt.open('xen://') >>> conn.listDomainsID() [0, 35, 36, 37, 38, 39, 40, 61] If I run the exact same thing remotely I get a list including numerous invalid IDs. This example shows the same host as shown above, about 20 seconds earlier (everything essentially identical): >>> import libvirt >>> conn = libvirt.open('xen+tls://xxxx.xxxxx') >>> conn.listDomainsID() [0, 35, 36, 37, 38, 39, 40, 51, 52, 53, 54, 60, 61] IDs 51, 52, 53, 54 and 60 are invalid. I first noticed this problem working with libvirt 0.6.0 on the client and 0.6.2 on the server, and noticed that with those versions the problem also occurred with virsh. Locally(0.6.0): local ~ # virsh list Id Name State ---------------------------------- 0 Domain-0 running 35 xxxxxxx idle 36 xxxxx idle 37 xxxxxx idle 38 xxxxxxxxx idle 39 xxxxxx idle 40 xxxxx idle 61 xxxxxxxxxx idle Whereas remotely(0.6.0): remote # virsh -c xen+tls://xxxxx.xxxxx list Id Name State ---------------------------------- 0 Domain-0 running 35 xxxxxxx idle 36 xxxxx idle 37 xxxxxx idle 38 xxxxxxxxx idle 39 xxxxxx idle 40 xxxxx idle libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon: libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon: libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon: libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon: libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon: 61 xxxxxxxxxx idle However with virsh 0.6.2 on the client this appears to be fixed.

[libvirt] Has anyone ever gotten the client or full to compile on OS X?

It's me. The original instigator of the long Leopard thread from early 2008.

[libvirt] LibvirtException: socket closed unexpectedly
by Marcel Michelmann 14 May '09

14 May '09

Hi *, I wrote a program in Java communicating with libvirt/XEN over SSH, with libvirt-java-0.2.1. I poll the CPU and RAM usage quite often (about 5 times a second). My program runs well about between 5-8 minutes, but then I get LibvirtException: socket closed unexpectedly. Although I try to catch the LibvirtExceptions with special System.out.println messages I have no idea where this is coming from. Now my question: what leads to this exception? exception caught: org.libvirt.LibvirtException: socket closed unexpectedly level:VIR_ERR_ERROR code:VIR_ERR_RPC domain:VIR_FROM_REMOTE hasConn:false hasDom:false hasNet:false message:socket closed unexpectedly str1:%s str2:socket closed unexpectedly str3:null int1:0 int2:0 After that I can start my program again, and it is the same again (runs some minutes and then throws the exception). Perhaps someone knows? I would be very thankful for any help! Best regards, Marcel

[libvirt] Latest git tree doesn't compile

Hello everyone, I just got the latest and grooviest libvirt from the git tree at : git://git.et.redhat.com/libvirt.git but compiling fails: /bin/bash ../mylibtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I.. -I../gnulib/lib -I../gnulib/lib -I../include -I../include -I../qemud -I/usr/include/libxml2 -DLIBDIR=\""/usr/local/lib"\" -DBINDIR=\""/usr/local/libexec"\" -DSBINDIR=\""/usr/local/sbin"\" -DSYSCONF_DIR="\"/usr/local/etc\"" -DLOCALEBASEDIR=\""/usr/local/share/locale"\" -DLOCAL_STATE_DIR=\""/usr/local/var"\" -DGETTEXT_PACKAGE=\"libvirt\" -Wall -Wformat -Wformat-security -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wextra -Wshadow -Wcast-align -Wwrite-strings -Waggregate-return -Wstrict-prototypes -Winline -Wredundant-decls -Wno-sign-compare -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fasynchronous-unwind-tables -g -O2 -MT lxc_driver.lo -MD -MP -MF .deps/lxc_driver.Tpo -c -o lxc_driver.lo lxc_driver.c (CC) -o lxc_driver.lo lxc_driver.c lxc_container.c: In function 'lxcContainerDropCapabilities': lxc_container.c:657: error: 'PR_CAPBSET_DROP' undeclared (first use in this function) lxc_container.c:657: error: (Each undeclared identifier is reported only once lxc_container.c:657: error: for each function it appears in.) Apparently, my machine doesn't have the PR_CAPBSET_DROP flag defined. It's inexistent in sys/capability.h and "man prctl". I run a Ubuntu 8.04, kernel is 2.6.24-24-openvz. Am I missing headers that are not tested for in the ./configure ? If not, any way that functionality could be disabled on distros that don't support it ? Thanks, Florian

[libvirt] [PATCH] avoid XML attributes escaping problems
by Daniel Veillard 13 May '09

13 May '09

The associated patch solves https://bugzilla.redhat.com/show_bug.cgi?id=499791 where ' or " character in attribute values may lead to non well-formed XML. This takes the simplest approach to always escape then to ' and " since this is completely equivalent from an XML point of view and avoid the trouble.

[libvirt] create domain for existing xp image
by Gunnar Thielebein 13 May '09

13 May '09

I want to create a domain for an existing xp machine via virt-install. The command is taken from this wiki article http://wiki.libvirt.org/page/QEMUSwitchToLibvirt: > virt-install --accelerate --hvm --connect qemu:///system -n xp -r 512 > --cdrom=/dev/null --file=WinXP.img --vnc --noautoconsole --os-type > windows --os-variant winxp --force When I start and connect I see message: > We apologize for the inconvenience, > ... > A recent hardware or software change might have caused this. When I look at the features I saw that it lacks acpi so it changes image HAL table. Is it intentional missing for that os/variant?

[libvirt] [PATCH 0/5] Interface Config public APIs and remote stubs
by Laine Stump 13 May '09

13 May '09

These 5 patches contain the public virInterface*() API definition, the local plumbing, and the RPC glue. The test driver and real driver are still TBI, but having this in will allow other people to work on related stuff. Other things still needed: python/java bindings cli commands in virsh I'm sure lots of other things I don't know about yet. Note that I have added a couple things to the API that I previously didn't realize were needed (virInterfaceRef and virInterfaceFree - I had figured the client side would just pass around a cookie, not actually have storage associated with it).
