If the guest agent is enabled and running, it calls guest-fsfreeze-freeze and guest-fsfreeze-thaw to improve consistency.

To freeze the guest file system when making a backup/snapshot (on windows, use the volume shadow copy service VSS).

To properly shutdown the guest, instead of relying on ACPI commands or windows policies.

In Proxmox VE, the qemu-guest-agent is used for mainly three things: To exchange information between the host and guest, and to execute command in the guest. The qemu-guest-agent is a helper daemon, which is installed in the guest. 2.3 Testing that the communication with the guest agent is working.1 Introduction - What is qemu-guest-agent.So the issue moves to the next subject, figuring out why that port is missing and if there is a way to add it. Given that the VM is up and running I'd prefer to not having to move everything to a new one. So I can just say as of now that the Alpine Virtual image, for some reasons, doesn't have the /dev/vport1p1 or 2p1 listed under dev. Qemu-ga -p /dev/vport2p1 works! To make the change permanent editing the files like mentioned in the alpine ticket issue also works fine. I can confirm (eventually) that using the Alpine Standard image I have the /dev/vport2p1 path and running I have no vport of any type under the /dev path EDIT 2Īll the abovementioned stuff is referred to the VM running Alpine Virtual. I've rebooted the machine between each try too with the same error: docker:~# qemu-gaġ578518273.999471: critical: error opening channel: No such file or directoryġ578518273.999491: critical: error opening channelġ578518273.999495: critical: failed to create guest agent channelġ578518273.999498: critical: failed to initialize guest agent channel I've also reverted these changes and tried what Weston Myers did (changing /etc/rc.conf ). (I've tried both /dev/vport1p1 and /dev/vport2p1 - Is there somewhere I can grab the correct path to use?)

My /etc/init.d/qemu-guest-agent script // Original fileĭocker:~# cat /etc/init.d/qemu-guest-agent.backupĬommand_args='-m $ -l /var/log/qemu-ga.log -d' Thanks for the great finding! However, I've tried to do what the guys mentioned without success, am I missing something? Woa, I am like the fourth user getting into this issue LMAO.
