The documentation says something that concerns me: http://libvirt.org/html/libvirt-libvirt.html#virConnectClose "It is possible for the last virConnectClose<http://libvirt.org/html/libvirt-libvirt.html#virConnectClose>to return a positive value if some other object still has a temporary reference to the connection, but the application should not try to further use

Hi, Is virsh able to access the VMX config of a virtual machine running on a esxi host? I would like to take backups of my virtual machine configs and the doku section "Converting from VMware VMX config to domain XML config" (http://libvirt.org/drvesx.html) comes close to this - but does not tell how to get access to the vmx file. I would prefer a solution where ssh access to the

hello everybody and happy new year! I am a newbie in libvirt use, and I use it mostrly throught OpenNebula. Anyway, I noticed that one of the nodes can be a destination of a livemigrate but not the source. This is the environment: 4 blades nicknamed(*) red3, red9, red10, red11, each with 8 Intel E5506 cores (@ 2.13GHz) running CentOS 5 and KVM as hyoervisor. (*) these are names I

libguestfs usually needs qemu. However it only requires an emulator for the same architecture, not for all architectures. libvirt-daemon-kvm pulls in qemu which pulls in emulators for all architectures, as well as a bunch of other stuff we don't need at all like network interface support and nwfilter. There are no Fedora TCG-only arches, so drop the conditional section. I also made support

This is an extended version of: https://www.redhat.com/archives/libguestfs/2019-September/msg00178.html It adds a couple of simple code changes, so it makes it possible to drop more modules. In addition, more unused modules were dropped. Pino Toscano (5): tests: switch away from xgetcwd daemon: move read_whole_file to common utils daemon: switch from read_file to read_whole_file daemon:

This is an extended version of: https://www.redhat.com/archives/libguestfs/2019-September/msg00288.html Apparently I forgot it on my tree, so I'm posting that series again, adding an extra cleanup more due to the v2v/common splits.
