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.
