...at's the best way to tell if a virConnect object is not good to use anymore? (For example because the libvirtd on the other side crashed/has been stopped or because of some network failure) When I try this, the first API call I do on a broken connection yields an error with error number 38 (VIR_ERR_SYSTEM_ERROR) and all subsequent calls yield an error number 1 (VIR_ERR_INTERNAL_ERROR). Both of those are really unhelpful and could mean just about anything... Guido

...e those steps needed? Randomly checking virConnectIsAlive() doesn't seem reliable. Checking individual error codes either (maybe I will miss one of them or misinterpret another one). virsh code uses those error codes to check if there is a disconnection: (((last_error->code == VIR_ERR_SYSTEM_ERROR) && (last_error->domain == VIR_FROM_REMOTE)) || (last_error->code == VIR_ERR_RPC) || (last_error->code == VIR_ERR_NO_CONNECT) || (last_error->code == VIR_ERR_INVALID_CONN)))) Any hint? -- Program defensively....

libvirt-ocaml is used only by virt-v2v, so move it to this repository, instead of having it around in the common submodule. The removal from common will happen later. Pino Toscano (2): common: Bundle the libvirt-ocaml library for use by virt-v2v build: switch embedded copy of libvirt-ocaml .gitignore | 2 + 3rdparty/libvirt-ocaml/Makefile.am |

Hi, this is a mostly done attempt to switch to ocaml-libvirt, embedding the latest version of it from git. This way, it is possible to improve the way v2v connects to libvirt for both input, and output modules, and interacts with libvirt (e.g. no more virsh calls needed in virt-v2v). As side effect, virt-v2v now requires libvirt, as keeping it optional would create too much burden. I could not
