Good afternoon friends.
Whenever I need to shut down or take a virtual machine takes enough. Almost 5 minutes.
Is there anything that can be done to improve this time?
 
There is a lot you can improve, but you have to elaborate what you already have. Without any facts about your system you can have a x86_64-based watch running proxmox up to a 16-node streched-mega-cluster.
 
do you use the qemu-guest-agent?

if not, enable it on the GUI (and install the package inside your VM)
 
My cluster has 6 active nodes, within 20 days i will enable more 6 nodes. (all nodes is dell 2950, 8x core and 32GB ram). Yes, QEMU agent is enable in all vm.
I did a test and it was better, I made the suspension of the server and then he did stop. It was fast then before.
But if I put the virtual machine to stop directly it takes a long time.

I use the latest version Proxmox and community license.
 
if a VM shutdown take 5 minutes, you should analyse the applications inside.
 
I will check this.
All vm running wordpress website only.
Mysql - php-fpm - varnish and nginx.

Anyway thank you for your attention and availability of all.
 
maybe you have issues with mounts? e.g. NFS.

just a guess.
 
Normally, I have start times for KVM of 2-5 seconds (most of the time I see the seabios) and shutdown of 2 seconds on Debian Jessie. What OS do you use inside?
 
Here is very fast to start too, but shutdown no ^^
Centos 6.7, kernel 3.x.
I will test other operating systems to see the results, thanks lnxBill.
 
Is there something shown on the console while shutting down? Normally, 6.7 is still very "noisy" compared to systemd-based RHEL 7 series.

I do not use CentOS a lot, but my RHEL and Oracle Linux VMs work as expected. Not as fast as Debian, but really fast.
