![]() ![]() Note: if shutdown functionality is not needed, blacklisting the guest-shutdown command helps to avoid the hangup in case the hypervisor issues the command nevertheless (but keep in mind it will be discarded, may have unintended side effects in the hypervisor logic). I'll also try to install it via rpm-ostree for now, but I believe the best solution would be to get the agent integrated properly into the base image. Hence I don't think the container approach is worth the effort when requiring shutdown capabilities. It is designed to improve communication between the host machine and KVM/QEMU virtual guests. So I suppose this would need addition of several extra scripts or similar modifications to the guest agent container to make it work, deviating significantly from the premise of a simple setup via the container. provides a software tool called the QEMU guest agent. by having systemd available inside the container and mounting appropriate sockets from the host, or via SysRq, see also for some hints). I get the message 'Guest Agent not running' on Proxmox, although on windows the Guest Agent is installed and confirmed running with Get-Service QEMU-GA. I'd say shutting down the host from within a container is an interesting task in general, although possible in general it usually requires some extra tricks (e.g. Guest agent not running (w/ QEMU guest agent enabled in host options and virtio installed in guest) I am having a strange bug showing up. This is not available in a standard container. It allows the hypervisor host to perform various operations in the guest, such as. ![]() The reasons is probably the way the feature is implemented in the agent itself, as it tries to call /sbin/shutdown ( ). The QEMU Guest Agent is a daemon intended to be run within virtual machines. None of the listed fixes are sufficient to provide a complete solution, as shutdown is still not possible from within the container - the agent simply does not crash or complain anymore, but it hangs upon requesting a shutdown. Changing things with the editor straightened things out.Podman run -privileged -rm -pid=host -ipc=host -net=host -v /dev:/dev -it linuxkit/qemu-ga:v0.7 /usr/bin/qemu-ga -m virtio-serialĪny suggestions for what I could do to make this work? I hadn't changed my xml with the editor in a long time and apparently messed things up with some manual editing. 10:31:50.426+0000: 7159: error : qemuAgentSend:866 : Guest agent is not responding: Guest agent not available for now 10:30:15.849+0000: 7157: warning : qemuDomainObjTaint:7831 : Domain id=4 name='Handyman' uuid=913f649f-9692-6e90-629e-94f6e067c0c0 is tainted: high-privileges The QEMU Guest Agent is a daemon intended to be run within virtual machines. 10:26:18.213+0000: 7160: warning : qemuDomainObjTaint:7831 : Domain id=3 name='Handyman' uuid=913f649f-9692-6e90-629e-94f6e067c0c0 is tainted: high-privileges The QEMU Guest Agent is a daemon intended to be run within virtual machines. A program run as part of the setup did not finish as expected. If I attempt to install it from the guest-agent subdirectory I get 'QEMU guest agent' window with message 'There is a problem with this Windows Installer package. 10:21:19.120+0000: 7158: error : virDomainDefRejectDuplicateControllers:3966 : XML error: Multiple 'scsi' controllers with index '0' This agent is a helper daemon that exchanges information between the quest and the host and executes commands in the guest for snapshot or backup.

This seems like something to do with the VM XML file. Libvirt uses the Qemu guest agent running inside a VM. Some of this is normal (at least they show up on mine), but there is also stuff about Qemu monitors and Guest agents being unavailable. Your libvirt logs has some things I have never seen that seems to pertain. This shouldn't really help, but there is a new version of this, you can get it here:Īlso, need the XML files from the VM in question. The Red Hat Virtualization guest agents, tools, and drivers provide additional functionality for virtual machines, such as gracefully shutting down or rebooting virtual machines from the VM Portal and Administration Portal. I believe it also has to do with the "Balloon" driver stuff that no one uses on Windows because it is buggy and doesn't really work. ![]()
