I'm having a go at writing some PHP scripts to do simple things like view the status of VMs running on my Ubuntu KVM host. I've installed php_libvirt_php but am failing at the first hurdle at the moment as I can't get the PHP script to connect. My normal way of connecting virsh from the command line is like this: $ virsh -c qemu+ssh://localhost/system This asks for a password which

Hi Guys, I was trying to suspend a virtual machine but fail not sure why.... However i was successfully list all the vm on the host, below are my source code, can any one who have experience in this area give me some advised ? *My OUTPUT from browser* Array ( [libvirt.release] => 3 [libvirt.minor] => 9 [libvirt.major] => 0 [connector.version] => 0.4.3

...fprintf(stderr, " str2: %s\n", err->str2); fprintf(stderr, " str3: %s\n", err->str3); fprintf(stderr, " int1: %d\n", err->int1); fprintf(stderr, " int2: %d\n", err->int2); } int init_libvirt() { virSetErrorFunc(NULL, libvirt_error_handler); libvirt_connection = virConnectOpen("qemu:///system"); ..... i will also check virConnectListAllDomains with correct pointer instead of null later, now have some other work to do.
