[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. I once again need to do libvirt development from my Mac, and I still cannot seem to get it to compile :( It is currently bugging out at: gcc -DHAVE_CONFIG_H -I. -I.. -I../gnulib/lib -I../gnulib/lib -I../ include -I../include -I../qemud -I/usr/include/libxml2 -DLIBDIR=\"/opt/ libvirt//lib\" -DBINDIR=\"/opt/libvirt//libexec\" -DSBINDIR=\"/opt/ libvirt//sbin\" -DSYSCONF_DIR=\"/opt/libvirt//etc\" -DLOCALEBASEDIR=\"/ opt/libvirt//share/locale\" -DLOCAL_STATE_DIR=\"/opt/libvirt//var\" - DGETTEXT_PACKAGE=\"libvirt\" -Wall -Wformat -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 -I/opt/local/include -g -O2 -MT pci.lo -MD -MP -MF .deps/pci.Tpo -c pci.c -fno-common -DPIC -o .libs/pci.o pci.c: In function 'pciFindStubDriver': pci.c:652: error: 'MODPROBE' undeclared (first use in this function) pci.c:652: error: (Each undeclared identifier is reported only once pci.c:652: error: for each function it appears in.) make[3]: *** [pci.lo] Error 1 make[2]: *** [all] Error 2 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 Any help is appreciated. -- -a "Ideally, a code library must be immediately usable by naive developers, easily customized by more sophisticated developers, and readily extensible by experts." -- L.

[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).

[libvirt] PATCH: Fix virsh reporting open errors

[libvirt] [PATCH 0/7] virStorageVolCreateXMLFrom API
by Cole Robinson 12 May '09

12 May '09

Hi all, The following patches implement a new API call: virStorageVolCreateXMLFrom. virStorageVolPtr virStorageVolCreateXMLFrom(virStoragePoolPtr pool, const char *xmldesc, unsigned int flags, virStorageVolPtr clonevol) Arguments function similar to the regular volume create API, except the parameter 'clonevol' is used as the input source. The API allows for volume cloning, possibly across pools, or within the same pool but converting volume formats. Tests I performed (and ensured that a VM booted without complaints from the new image): Raw -> Raw (with successful sparse detection) Raw -> QCOW2 QCOW2 -> Raw QCOW2 -> QCOW2 QCOW2 -> VMDK Raw partition ('disk' volume) -> Raw file Thanks, Cole Cole Robinson (7): Add public API stubs for virStorageVolCreateXMLFrom Remote driver plumbing for virStorageVolCreateXMLFrom Test driver implementation of virStorageVolCreateXMLFrom Virsh commands vol-clone and vol-create-from Storage driver implementation for CreateXMLFrom Break out FS volume build routines to their own functions.
