Of course the other thing to note is that we do have some very experimental libvirt.dll binaries available. The posting below has all the details: https://www.redhat.com/archives/libvir-list/2008-January/msg00072.html Don't let that stop you from trying to build it yourself ...

There's a couple of odd things about this. Firstly: In file included from ../gnulib/lib/sys/stat.h:28, from remote_internal.c:36: ../gnulib/lib/sys/stat.h: In function 'rpl_mkdir': ../gnulib/lib/sys/stat.h:272: warning: unused parameter 'mode' In file included from remote_internal.c:61: getaddrinfo.h:38:19: error: netdb.h: No such file or directory In file included from remote_internal.c:61: getaddrinfo.h: At top level: getaddrinfo.h:199: error: redefinition of 'struct addrinfo' getaddrinfo.h:214: error: conflicting types for 'gai_strerrorA' c:\mingw\bin\../lib/gcc/mingw32/4.2.1-sjlj/../../../../include/ws2tcpip.h:309: error: previous definition of 'gai_strerrorA' was here According to ./configure, <netdb.h> header file wasn't found, as expected, but the Gnulib implementation of getaddrinfo shouldn't be trying to include it in this case. In Gnulib's getaddrinfo.h we have: #ifdef HAVE_NETDB_H # include <netdb.h> #endif But I think you're including some other <getaddrinfo.h> from somewhere else. My version of MinGW doesn't have any file called getaddrinfo.h (which is why we're using the one from Gnulib in the first place), so I suspect either you're using some later version of MinGW or else you've got MinGW & Cygwin files mixed up, or you've got some other implementation of getaddrinfo installed. Secondly: ../qemud/remote_protocol.h:509: error: expected specifier-qualifier-list before 'u_int64_t' In this file from CVS, line 509 is: typedef struct remote_domain_get_max_vcpus_args remote_domain_get_max_vcpus_args; and I don't see how this line can provoke the error. You'll need to use the versions of qemud/remote_protocol.[ch] from CVS, along with PortableXDR (see yesterday's posting) or my hacked up xdr-4.0-mingw5 library.

[Libvir] Libvirt on windows
by Gabriel Kaufmann 24 Jan '08

24 Jan '08

Hi, Did anybody managed to compile libvirt-0.4.0 on windows. I tried following instructions on http://libvirt.org/windows.html which offer compiling in Cygwin. This doesn't work because of inconsistency with winsock2. If I change manually the HAVE_WINSOCK2 macro and make some changes in the code (see https://www.redhat.com/archives/libvir-list/2008-January/msg00344.html ) I manage to compile but after compiling virsh doesn't work (don't manage to connect to the host and returns Bad Address immediately) Then I tried following the (not so detailed) instructions in https://www.redhat.com/archives/libvir-list/2008-January/msg00017.html I get error compilation: In file included from remote_internal.c:73: ../qemud/remote_protocol.h:1218:2: error: #endif without #if remote_internal.c: In function 'remoteDomainGetMaxMemory': remote_internal.c:1581: error: 'remote_domain_get_max_memory_ret' has no member named 'memory' remote_internal.c: In function 'remoteDomainSetMaxMemory': remote_internal.c:1591: error: 'remote_domain_set_max_memory_args' has no member named 'memory' remote_internal.c: In function 'remoteDomainSetMemory': remote_internal.c:1608: error: 'remote_domain_set_memory_args' has no member named 'memory' remote_internal.c: In function 'remoteDomainGetInfo': remote_internal.c:1634: error: 'remote_domain_get_info_ret' has no member named 'max_mem' remote_internal.c:1635: error: 'remote_domain_get_info_ret' has no member named 'memory' remote_internal.c:1636: error: 'remote_domain_get_info_ret' has no member named 'nr_virt_cpu' remote_internal.c:1637: error: 'remote_domain_get_info_ret' has no member named 'cpu_time' remote_internal.c: In function 'remoteDomainMigratePrepare': remote_internal.c:1846: error: 'remote_domain_migrate_prepare_args' has no member named 'flags' remote_internal.c:1847: error: 'remote_domain_migrate_prepare_args' has no member named 'dname' remote_internal.c:1848: error: 'remote_domain_migrate_prepare_args' has no member named 'resource' remote_internal.c: In function 'remoteDomainMigratePerform': remote_internal.c:1882: error: 'remote_domain_migrate_perform_args' has no member named 'flags' remote_internal.c:1883: error: 'remote_domain_migrate_perform_args' has no member named 'dname' remote_internal.c:1884: error: 'remote_domain_migrate_perform_args' has no member named 'resource' remote_internal.c: In function 'remoteDomainMigrateFinish': remote_internal.c:1911: error: 'remote_domain_migrate_finish_args' has no member named 'flags' make[2]: *** [libvirt_la-remote_internal.lo] Error 1 make[2]: Leaving directory `/data/cvs/libvirt/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/data/cvs/libvirt' Can anyone tell help?

[Libvir] Empty <bootloader> tag?
by Kaitlin Rupert 23 Jan '08

23 Jan '08

Hello, I created a guest from XML without a <bootloader> tag. When I run dumpxml on the guest, I notice that an empty <bootloader /> tag is appended. Is this the expected behavior? This seems to differ from the behavior of other optional tags. Thanks!

[Libvir] PATCH: Remove use of PKG_CHECK_EXISTS
by Daniel P. Berrange 23 Jan '08

23 Jan '08

This patch removes the use of PKG_CHECK_EXISTS which is only available in new versions of pkg-config. Instead we use the 3rd and 4th args of the PKG_CHECK_MODULES macro to control the if-found/not-found behaviour. This allows us to auto-disable features if they're missing, rather than aborting the configure run. This patch also updates the SASL tests to support the value 'check' for auto-enable/disable like the rest of the modules. With this applied I can successfully run the following on RHEL-4 hosts with the default RPMs installed ./autogen.sh --without-xen make make dist Dan. -- |=- Red Hat, Engineering, Emerging Technologies, Boston. +1 978 392 2496 -=| |=- Perl modules: http://search.cpan.org/~danberr/ -=| |=- Projects: http://freshmeat.net/~danielpb/ -=| |=- GnuPG: 7D3B9505 F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 -=|

[Libvir] Libvirt on Mac OS X 10.5
by Richard W.M. Jones 23 Jan '08

23 Jan '08

I got a little bit further with this, my current patch is attached. At the moment, it gets as far as building libvirt & virsh, but fails to build the Python bindings. However virsh doesn't run, apparently because of a simple dynamic linking problem because of where the libraries are (not yet) installed. I'm afraid that my understanding of how to build and install applications on Mac OS X ends around here. In particular I have no idea how to get the detailed abort trace that Andrew showed up in his previous email. References to portablexdr will be explained in a forthcoming email.

[Libvir] API "int virDomainRestore(Conn, from)"
by Daniel Schwager 23 Jan '08

23 Jan '08

Hi, I would like to restore a domain. I think, after restoring the domain, the vnc-port maybe has changed (because e.g. another domain use the old VNC-port at the meantime). If I do not know the domainname I restored, I have no possibility to get this vnc-port or connect to the restored domain. Is this correct ? So, would it not be better to change the API to virDomainPtr virDomainRestore(Conn, from) regards Danny ------------------------------------------------------------------- DT Netsolution GmbH - Taläckerstr. 30 - D-70437 Stuttgart Geschäftsführer: Daniel Schwager, Stefan Hörz - HRB Stuttgart 19870 Tel: +49-711-849910-32, Fax: -932 - Mailto:daniel.schwager@dtnet.de

[Libvir] Any sample code to use virConnectOpenAuth() in C binding ?
by Arun Sharma 23 Jan '08

23 Jan '08

Hello All, Can anyone provide me sample code for connecting hypervisor using credentials. As of now i have implemented using(virConnectOpen(NULL)) , but this function does not takes any credential information. I saw that there is function (virConnectOpenAuth()) which can be used , but i don;t know any way to implement Thanks in advance. -- Regards Arun Sharma 0-934-829-3810

[Libvir] Windows sizeof(long) != Linux sizeof(long)
by Daniel P. Berrange 23 Jan '08

23 Jan '08

Just discovered that on x86_64, Windows and Linux differ in what they think sizeof(long) to be. http://lists.xensource.com/archives/html/xen-devel/2008-01/msg00736.html http://www.winehq.org/pipermail/wine-devel/2005-July/038602.html Windows i686: sizeof(long) == 4, sizeof(void*) == 4 Windows x86_64: sizeof(long) == 4, sizeof(void*) == 8 Linux i686: sizeof(long) == 4, sizeof(void*) == 4 Linux x86_64: sizeof(long) == 8, sizeof(void*) == 8 Unfortunately we have a number of APIs which use 'long' in the public header file for dealing with VM memory. Fortunately they are all using memory in size of KB, so we are not totally doomed until people start wanting to manage VMs with > 2 TB of RAM. Also fortunately, the wire-encoding for these APIs all uses hyper, so on the wire everything is 64-bit guarenteed. Eventually though we might want to consider adding struct virDomainInfo64 struct virNodeInfo64 virDomainGetMemory64 virDomainSetMemory64 virDomainSetMaxMemory64 ....simply replacing 'long' with 'long long' in these 5 APIs so we have public APIs whose precision matches the wire encoding. More immediately though, we need to be careful that there is no code that assumes sizeof(long) == sizeof(void*) - eg any places we cast pointers to integers and back again will break on Windows 64. Again fortunately, so far I can only find places going from int -> pointer -> int which is OK because we're not loosing precision.
