Hi Alex Thank you for your reply. I just wanna make sure I'm not misunderstanding, virStorageVolGetXMLDesc & virStorageVolCreateXMLFrom together can do the clone process, am I right? In fact, libvirt will call a group of APIs to complete vol-clone operation, you can track the whole calling process, it looks like this: virsh vol-clone <vol-key> <newname> | V
virConnectOpenAuth | V virStorageVolLookupByKey | V virStoragePoolLookupByVolume ('default' is default pool) | V virStorageVolGetXMLDesc | V virStorageVolCreateXMLFrom | V virStorageVolGetName (twice) | V virStorageVolFree (twice) | V virStoragePoolFree | V virConnectClose Alex

Hi lancer, As Osier said, libvirt hasn't a independent API for cloning an existing guest, instead of using virStorageVolGetXMLDesc API to get a guest volume xml description and then calling virStorageVolCreateXMLFrom API to clone a new volume. For python-virtinst component, you may use virt-clone to implement this, for libvirt component, you may directly use python binding API or virsh tool 'vol-clone' to implement it. I hope it's helpful for you. - Alex ----- Original Message ----- From: "黄亮" <lancerhuang@163.com> To: "libvir-list" <libvir-list@redhat.com> Sent: Wednesday, November 10, 2010 9:30:28 AM GMT +08:00 Beijing / Chongqing / Hong Kong / Urumqi Subject: [libvirt] Is there an API for clone? Hi, guys I know there is a command "virt-clone", but I couldn't find the equivalent API here : http://libvirt.org/html/libvirt-libvirt.html
So, is there an API to clone an existing VM or not? Thank you!
