Hi there, I've been trying to use libvirt-php to bring libvirt support to jentu which runs on mostly Debian Wheezy machines. I've had a few bugs setting network devices as active with the released (0.4.8) version: PHP Warning: libvirt_network_get_information(): Invalid XPath node for network gateway IP address in /var/www/libjentu-virt.php on line 54 PHP Warning: libvirt_network_set_active() expects exactly 2 parameters, 1 given in /var/www/libjentu-virt.php on line 55 PHP Warning: libvirt_network_set_active(): Invalid arguments in /var/www/libjentu-virt.php on line 55 Building the latest Git repository results in: gcc -g -O2 -Wall -fpic -DCOMPILE_DL_LIBVIRT=1 -I/usr/include/php5 -I/usr/include/php5/main -I/usr/include/php5/TSRM -I/usr/include/php5/Zend -I/usr/include/php5/ext -I/usr/include/php5/ext/date/lib -c -o libvirt-php.o libvirt-php.c -I/usr/include/libxml2 -DHAVE_CONFIG_H libvirt-php.c: In function ‘zm_startup_libvirt’: libvirt-php.c:1179:2: error: ‘VIR_DOMAIN_VCPU_GUEST’ undeclared (first use in this function) libvirt-php.c:1179:2: note: each undeclared identifier is reported only once for each function it appears in libvirt-php.c: In function ‘get_next_free_numeric_value’: libvirt-php.c:2719:6: warning: format ‘%x’ expects argument of type ‘unsigned int *’, but argument 3 has type ‘long int *’ [-Wformat] make[2]: *** [build] Error 1 And this is because debian wheezy has an old version of libvirt that does not have this declared. The proper solution looks like it'd be a configure-time check and enable or disable the new VCPU guest modifiers if they are not available because I'm not so sure wheezy will ever get a newer version of libvirt.
