[libvirt-users] Libvirt supported qemu-ga commands
Where can I find the full list of libvirt supported qemu-ga commands? The docs [0] imply virDomainQemuAgentCommand bypasses libvirt and is not recommended. I am looking to pass suspend/resume events from the host to the guest and then have the guest act on this internally. Your help is appreciated. [0] https://wiki.libvirt.org/page/Qemu_guest_agent

Did some RTFMing [1], I guess if I go by the shutdown example I can suspend/resume via guest agent with these commands? virsh suspend --mode=agent virsh resume --mode=agent [1] https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm...

By suspend/resume, do you mean ACPI S3 suspend-to-ram events ? If so, that doesn't require guest agent involvement at all. Just requires virsh dompmsuspend virsh dompmwakeup Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|

virsh dompmsuspend virsh dompmwakeup

I see. Thats simpler but will the guest be "sentient" about the fact that it had just been resumed? I need it to know so that it triggers specific events in this case.

This works the same way as it does on physical hardware. Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
