Hello Everyone, I am facing a problem in defining the xml for domain creation using libvirt. I am using Xen hypervisor. domPtr = lib.virDomainDefineXML(conPtr, domainXML); I get the following error: "libvir: Xen Daemon error : XML error: failed to parse domain description" Any suggestions are welcome.

good day, i am trying to create domain via virDomainDefineXML. and my program hanging, also i failed to caonnect to libvirt daemon with virt-manager after this, only killing libvirtd via SIGKILL and restarting it solveing hang (i mean after restart i able to connect with virt-manager), i using following domain xml <?xml version="1.0" encodin...

Hi. I'm trying to change network settings for a domain via libvirt (the driver is xenapi) with no success. According to its sources, 'virsh edit' uses virDomainGetXMLDesc(), allows to edit the received xml and then use virDomainDefineXML(). In case of xenapi driver it leads to a new vm creation (with the same name and edited settings). Looking through the list of API functions I failed to find a function like virDomainUpdateXML() that would change configuration of existing domain. Could you please suggest a way to do it? Thank...

Hello, In my C++ code, I generate my own domain XML file and I use virDomainCreateXML or virDomainDefineXML to launch my qemu VM. However, when I get to check which commands are sent to the qemu commandline, I find that libvirt has added so many extra parameters to the ones I have already set. How can I prevent libvirt from adding any extra parameters to the ones I originally defined in the domain XML?...

hi, When I use dom = virDomainDefineXML(conn, xml) to define xml, I countered a problem that " libvir: Domain Config error : internal error incorrect root element". Could you please tell me what's wrong with it? I tend to debug such problem above by gdb to step into virDomainDefineXML. When I press "step" in gd...

hi : i create a domain by virt-manager tool, then there is a xxx.xml generated in /etc/libvirt/qemu/. so, my question is how the xx.xml generated? What the code involves in libvirt ? Thanks! -- Have a good day
