Re: [libvirt] Create domain using libvirt-php

Hi Ali, thanks for your e-mail, here are answers to your questions: 1) $iso_image is the location of ISO image to start installation from. This is the only supported installation source for now. 2) $disks is the array of disk settings, if you don't understand the description ("array of disk devices for domain, consist of keys as 'path' (storage location), 'driver' (image type, e.g. 'raw' or 'qcow2'), 'bus' (e.g. 'ide', 'scsi'), 'dev' (device to be presented to the guest - e.g. 'hda'), 'size' (with 'M' or 'G' suffixes, like '10G' for 10 gigabytes image etc.) and 'flags' (VIR_DOMAIN_DISK_FILE or VIR_DOMAIN_DISK_BLOCK, optionally VIR_DOMAIN_DISK_ACCESS_ALL to allow access to the disk for all users on the host system)") then it's simply this array: $disk1 = array( "path" => "/var/libvirt/images/vm.img", "driver" => "raw", "bus" => "ide", "dev" => "hda", "size" => "10G", "flags" => VIR_DOMAIN_DISK_FILE | VIR_DOMAIN_DISK_ACCESS_ALL ); $disks = array( $disk1 ); This means just one disk image will be created for the VM, the image will be created at /var/libvirt/images/vm.img with size of 10 Gigabytes and it will be the raw image (like a normal hard-drive is, i.e. no backing file or anything), on the IDE bus, presented to the guest as /dev/hda device, the path (/var/libvirt/images/vm.img)is referring to a file on disk (VIR_DOMAIN_DISK_FILE) and not a partition/block device and we will allow the access to this disk to all users (VIR_DOMAIN_DISK_ACCESS_ALL). 3) $networks => "a rray of network devices for domain, consists of keys as 'mac' (for MAC address), 'network' (for network name) and optional 'model' for model of NIC device" $network1 = array( 'mac' => '00:11:22:33:44:55', 'network' => 'default', 'model' => 'e1000' ); $networks = array( $network1 ); This specifies that there will be one network interface with MAC address of 00:11:22:33:44:55 added to the guest. This interface will be presented to the guest as the e1000 NIC and will be connected to the network 'default'. 4) $flags - this is the OR'ed int field of domain flags, those can be: /* Domain flags */ DOMAIN_FLAG_FEATURE_ACPI - support ACPI in the guest DOMAIN_FLAG_FEATURE_APIC- support APIC in the guest DOMAIN_FLAG_FEATURE_PAE- support PAE in the guest DOMAIN_FLAG_CLOCK_LOCALTIME- use localtime offset in the guest instead of UTC offset (MS Windows requires localtime offset AFAIK) DOMAIN_FLAG_SOUND_AC97 - support AC'97 sound card in the guest For reference please see: http://libvirt.org/php/api-reference.html#libvirt_domain_new If you would like to see the project using it and the usage, you can look to the php-virt-control project at http://www.php-virt-control.org site. The project is maintained and developed by me and few others and it's open-source as well. You can clone it's source codes from the project git (link available on the website). Hope this helps!
