Enable Qemu Guest Agent?
- Thread starter Afox
- Start date
you can only enable qemu-guest-agent for a whole vm
what is does is described here:
https://pve.proxmox.com/wiki/Qemu-guest-agent
it can only make things better
depends on the backup mode, snapshot would probably only be a very short freeze, suspend would loose the connection to novnc, and with stop the vm will be shut down
Easy answer: It depends :-D
You can hook into the agent to do more stuff, so it could take longer.
You can always test for yourself if you ping, e.g. every 100 ms and then run a backup. You can see when it is snapshotted and also if you would to a live migration. You will have a very, very smalls deviation of the ping response or rtt.
When are you guys updating the qemu-gest-agent wiki page? It is outdated (still from ve 4.0) 'Run guest-trim after clone disk' is not described.
I've done a lot of testing recently, and you can barely notice any issue during backup.
You really should install the agent.

"Run guest-trim after clone disk" option details. I was referencing the quoted post. Sorry for not be more specific.
I came here searching for information about 'Run guest-trim after clone disk' as well.
Why isn't there still any response on this by the proxmox team?
What does the function "Run guest-trim after clone disk" do?

Hi,

Code:
It is possible to enable the 'Run guest-trim' option. With this enabled,
{pve} will issue a trim command to the guest after the following
operations that have the potential to write out zeros to the storage:
* moving a disk to another storage
* live migrating a VM to another node with local storage
On a thin provisioned storage, this can help to free up unused space.Because we aren't that many people and can't keep track of every single forum thread.
Hi,
not really, because you also have to install it in the guest first. But, depending on how homogeneous your VMs are, you can create VM templates that have the guest agent already installed and configured. And if you clone new VMs off of those templates, they should still have the guest agent settings you configured.
