The spice-vdagent should be running in the guest. Have you installed the spice guest tools in your windows guest? Download them here: http://www.spice-space.org/download.html That should get clipboard sharing working. ----- Original Message ----- > From: "Laszlo Pal" <vlad@vlad.hu> > To: libvirt-users@redhat.com, virt-tools-list@redhat.com > Sent: Thursday, March 20,

...ying that, `mount` hangs when trying to mount a filesystem share again *after* restoring the snapshot (unmounting and remounting works perfectly before that, of course). Nothing is reported in syslog. I've also tried unloading combinations of the various 9p and virtio related modules (like 9p, 9pnet_virtio, 9pnet, virtio, etc) before taking the snapshot, and then reload them after restoring it, in hope of getting them into a sane state again (or whatever is the issue). But then I've seen errors like this in syslog: 9pnet: Installing 9P2000 support virtio-pci 0000:00:08.0: irq 42 for MSI/...

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:

I run latest sparse from git on virtio drivers (turns out the version I had was rather outdated). This patchset fixes a couple of bugs this uncovered, and adds some annotations to make it sparse-clean. In particular, endian-ness is often tricky, so this patchset enabled endian-ness checks for sparse builds. Michael S. Tsirkin (10): virtio_console: drop unused config fields drm/virtio: fix
