I don't see any reason why it shouldn't work correctly. Ok, looking at the XML parsing routines we don't currently support the 'ip' property. Fortunately, it looks as if one of Michel Ponceau's patches from a thread last week ought to solve this problem, so we ought to be able to get this working for next release.

Does the XML file format support routed? If so, what would the <interface> clause look like? -- Sargun Dhillon President Atarack Communications, Inc. (925)-202-9485

[Libvir] Problem with hypercall
by Jim Fehlig 02 Oct '06

02 Oct '06

Stumbled across a problem trying to list domains with libvirt-0.1.5. Using virsh I get errors such as xen81:/tests/jim # virsh list Id Name State ---------------------------------- 0 Domain-0 running libvir: Xen Daemon error : GET operation failed: No such domain 16 xm shows xen81:/tests/jim # xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 2048 4 r----- 815825.8 vm1 1 512 2 -b---- 0.3 I found that the buffer provided for XEN_V1_OP_GETDOMAININFOLIST hypercall differs slightly from the buffer in xen/dom0_ops.h. Attached is a patch against current cvs that works for me, but I'm not familiar with this part of the code so not sure if this is the proper fix. I'm using xen 3.0.2 that shipped with SLES10.

[Libvir] Proposal for virtual devices described in XML
by michel.ponceau＠bull.net 02 Oct '06

02 Oct '06

Proposal modified after comments from Daniel P. Berrange: /* Create a virtual device attachment to backend */ int virDomainAttachDevice(virDomainPtr domain, char *xml); /* Destroy a virtual device attachment to backend */ int virDomainDetachDevice(virDomainPtr domain, char *xml); /* @domain: pointer to domain object * @xml: pointer to XML description of one device * Returns 0 in case of success, -1 in case of failure. */ The XML would be in same form as the part of domain description for a single device, either <disk.../disk> or <interface.../interface>. In Detach function, the device is identified by its target name for "disk", and its MAC address for "interface". When the MAC address has not been assigned by Libvirt user at device creation, it must be retrieved from Xen using virDomainGetXMLDesc function.
