Sometimes I would like to see a screenshot of the virtual machine. Of course I could do this via the console also, but always start Java here and confirm all safety messages annoying sometimes. I would also use a static image here. Is there a way to do such a thing?

Is it possible to create the screenshot from the bash console, without a browser? Spice is only possible with additional tools. I mean a function which is similar to working under Virtualbox:
Here is a command to take a simple screenshot from the virtual machine:

Are you talking about the feature in Hyper-V where in the console gui it shows a static screenshot of the VM inside without actually opening a console into it?
Supermicro IPMI also has this feature in the Console GUI. I can see the usefulness when checking on many VMs without actually logging in through console. Could be placed where the Note box is in current Proxmox GUI. I think its a good candidate for feature request.
On debian the correct syntax is: screendump > /path/to/file
Reason: screendump dumps to stdout.
If tty is other than tty0 you need to add number for tty. Eg. if tty is tty1
screendump 1 > /path/to/file

I use the proxmox iso image with debian wheezy on board. In my system the screendump goes (connection with putty client) the normal output to a file rather than to stdout. So far I could not find a one liner for a bash script.
Code:
root@proxvm2:~# qm monitor 181
Entering Qemu Monitor for VM 181 - type 'help' for help
qm> screendump /tmp/test.ppm
qm> quit
root@proxvm2:~# ls -l /tmp/test.ppm

For me it is now a simple solution. An improvement or a feature request would be to be able to see this image automatically in Proxmox webinterface. What do you say?
Can you fill a request in proxmox bugtracker ?
Has anyone been able to figure out how to pipe commands into the qm monitor? I have a project and the ability to grab a screenshot is necessary! Tried using SOCAT, but I'm not familiar with how it works, or if it even does. This is a new install of PVE 5.4. Thanks in advance!
You can automate it with expect (have to install it first, best with --no-install-recommends):
Code:
root@proxmox1 ~ > ls -l /tmp/test_12002.ppm
/bin/ls: cannot access '/tmp/test_12002.ppm': No such file or directory
root@proxmox1 ~ > ./screenshot 12002
spawn qm monitor 12002
Entering Qemu Monitor for VM 12002 - type 'help' for help
qm> screendump /tmp/test_12002.ppm
qm> quit
root@proxmox1 ~ > ls -l /tmp/test_12002.ppm
-rw-r----- 1 root root 2359312 Mar 10 23:34 /tmp/test_12002.ppm
root@proxmox1 ~ > cat screenshot
#!/usr/bin/expect
set timeout 10
set id [lindex $argv 0]
spawn qm monitor $id
expect "qm>"
send -- "screendump /tmp/test_$id.ppm\r"
expect "qm>"
send -- "quit\r"
expect eofHey there, thanks to @Moayad for pointing me in this direction I got it to work!
You can make screendump with API CLI [0], also you can write an bash script to do that.
Example:
# pvesh create /nodes/{node}/qemu/{vmid}/monitor --command "screendump /tmp/test"
# display /tmp/test
