Two options in VM options. What do they do?

[Nemesis11]

Hi,

We use proxmox since version 3 and we upgraded to version 4 and now we are running the latest version. 4.1 with the last updates.

I was browsing "VM options" in one VM when i found two options that i don't remember in version 3.

I googled these two option but i dind't found their meaning.

I post this thread to ask for an explanation to these two options.

The options are:
- Qemu agent
- VM protection

Can someone explain what they do?

Thanks

Qemu agent

This is support for communication between proxmox host and VM through QMP (QEMU management protocol) like VmWare tools.

Thanks for your answer.

Where can i find the agent? Is it like vmware where it mounts an iso file in the cd rom and then we proceed to install the agent?
Is it only for windows? Is there a version for linux?

We have only Centos 6 KVM virtual machines. Does it make sense that we activate this option in Centos 6 Virtual Machines? If yes, where can i find the agent?

If someone could explain "VM Protection" i would appreciate.

The package is named spice-vdagent and is part of the EPEL repo.

Thanks. I will try it in a test VM.

you check it and you can not delete your vm, until you uncheck it that is.
That is at least how I use that setting to prevent "temporary Insanity" from deleting the wrong VM

Oh thanks. That is a good option to have enabled.

Thank you all
