Hello,

Thank you for posting this great utility. I found it from the Proxmox forum post you made here: https://forum.proxmox.com/threads/remote-spice-access-without-using-web-manager.16561/page-5

I am using it successfully now, but I was wondering if there is a way of optionally disabling the cmd/console window that launches with the session?

Thanks again,

~ndr

Hi,

I have the same issue as discussed and i am opening an issue here as you suggested some time ago.
https://forum.proxmox.com/threads/virt-viewer-connection-to-proxmox-vms-from-network-clients.91295/

i'd appreciate your help.

Hi So thanks for the super nice application. It just work perfectly, set the proxy ip option and hop. Just small question: after connection, the command prompt pump lot of message about :
(remote-viewer.exe:7140): CRITICAL **: 14:49:10.206: gst_app_src_push_internal: assertion 'GST_IS_APP_SRC (appsrc)' failed

I haven't find what it mean. Any idea ? run over prox 7.1 Was it about a system security or certificate ? just to know

thanks in advance

Hi,

I have trouble making this work, unfortunately :(
This is my command line call: cv4pve-pepper.exe --host=HOST.lan --api-token 'cv4pve@pve!spice=uuidhere' --vmid 400 --viewer D:\Apps\Applications\VirtViewer\bin\virt-viewer.exe (System: Windows 11 23H2 x64"
The call returns nothing (but no error either)

And I get this message box that says "Unable to connect to libvirt with URI: [none]"

I've checked the permission of mycv4pve user, and I can open a SPICE console from the web GUI.
I also checked that I assigned an API Token permission specifically to the 400 VM

Any help welcome!

I am using the tool with Ubuntu 20.04.

/opt/cv4pve-pepper/cv4pve-pepper --host=192.168.2.5 --username=root@pam --password=root123 --vmid=101 --viewer /usr/bin/remote-viewer
I get always the error "Problem connection!". What's wrong?
I started it with --debug too. But where is the log?

Regards Steffen

Hi Frank,

Thanks for your app, it greatly simplifies my windows spice connections and for that, I thank you. I was wondering if I could forward this cv4pve-pepper app to Xquartz through ssh -XY etc I have tried it with exporting DISPLAY as a shell and I have tried running the app as a forward ssh session. Remote Viewer runs ok in XQuartz?

any idea if your cv4pepper will forward through ssh -XY session, it appears to run but I don't get an XQuartz window opening, I have installed firefox and it runs ok.

Hi,

this version cv4pve-pepper-linux-arm works on RaspberryPi Model B?

thanks

It says Error: unknown host x.x.x.x

If I set the node's firewall to No, it works fine. What firewall exceptions do I need to make?

cv4pve-pepper --username root@pam --password test --host saturn.home --vmid 120 --viewer /usr/bin/virt-viewer

I have confirmed the vmid

Hi all,

Would it be possible to pass some command line arguments like -f and -z to remote-viewer while calling cv4pve-pepper? I would like to script for starting zoomed and in full-screen for some of my guests, but the remote-viewer line doesn't like having arguments at the end and fails to launch.

hi, i cannot run cv4pve-pepper succesfully, The file 'remote-viewer' does not exist. but all seems to be ok with remove viewer, how to fix it?

Does not work with lxc container.
cv4pve-pepper.exe" --host 192.168.10.122:8006 --username root --password ******* --vmid 733 --viewer "C:\Program Files\VirtViewer v11.0-256\bin\remote-viewer.exe"
Returns an error "Configuration file 'nodes/pve/qemu-server/733.conf' does not exist"
lxc container are located in 'nodes/pve/lxc/733.conf'
What am I doing wrong?

hi
my english is bad, sorry
after downloading, unziping and starting
i get error
Cannot find guest domain /tmp/tmpJYBd7G.vv
./cv4pve-pepper --host=10.192.10.132:8006 --username=root@pam --password=password --vmid=100 --viewer=/usr/bin/virt-viewer
How fix ?
Thx advice

Hi, you have this example:

cv4pve-pepper --host=192.168.0.100 --username=root@pam --password=fagiano --vmid 100 --viewer path-spice-viewer

but i want to connect with --api-token

can you give example, how to use --api-token instead of --password ?

ERROR: One or more errors occurred.

Hello,

Starting the cv4pve-pepper.exe on Windows 10 only returns an error message from remote viewer, stating the connection to the grafic-server using the vv-file cannot be established.

Using the Windows Explorer, I searched for the vv-file. There is no vv-file of the stated name, only an empty tmp-file, but maybe remote viewer has already deleated it.

I am able to connect to spice using the webinterface and the user I created for this matter.

Arguments used:
--host=192.168.178.10 --username=username@pam --password=password --vmid 101 --viewer "C:\Program Files\VirtViewer v11.0-256\bin\remote-viewer.exe"

Error message (German):

Hello Frank,
First of all thank you for this wonderful tool,just tested windows x64 version with parameter --proxy with success.
I just made 3 node Proxmox 7 HA Ceph cluster for our VDI needs,is it possible add HA multiple host support for parameter --proxy?

or is it needed?what happens when SPICE proxy server is dead?will all remote-viewer clients will drop connection?

Thanks in advance,
Hafiz.

Hi, when executing the following command on unubtu desktop 16.04:

./cv4pve-pepper --host=10.0.2.20 --username root@pam --password PWD --vmid 104 --viewer /usr/bin/remote-viewer

all I get is

already tried with and without port after the host

Proxmox 6.2.4
cv4pve 1.3.1

any hint?
Thanks

When I execute the script in U20.04, it executes but nothing happens.
./cv4pve-pepper --host=192.168.1.111 --username=root --password=secret --vmid 100 --viewer /usr/bin/virt-viewer
I'm using the following:
--host=IP of the Proxmox server
--username=same username as when logging in to Proxmox from the web interface
--password=same password as when logging in to Proxmox from the web interface
--vmid=virtual machine number in Proxmox
Adding the --debug switch reveals a "no spice port" error. Where do I specify the Spice port?

I run my Proxmox VE using frp reverse proxy for remote access. The local web gui page https://192.168.123.182:8006/ is redirected to https://43.249.xxx.xxx:55012 and the local's 3128 port is also redirected to remote 55011 port.

If I want to use SPICE remotely, I have to download the .vv file and quickly edit the proxy's line from proxy=http://43.249.xxx.xxx:3128 to proxy=http://43.249.xxx.xxx:55011 in able to connect. Since the *.vv file expires in 30 seconds, it's not easy to do so.

So I searched around and found this project, but it seems it can's specify the port for the proxy either. If I run this command, it can fetch the .vv file, but it's still using the 3128 proxy port.

.\cv4pve-pepper.exe --host 43.249.xxx.xxx:55012 --username root@pam --password ****** --vmid 110 --viewer "C:\Program Files\VirtViewer v9.0-256\bin\remote-viewer.exe" --proxy 43.249.xxx.xxx --debug

If I run this command by adding the port, it can't fetch the .vv file

.\cv4pve-pepper.exe --host 43.249.xxx.xxx:55012 --username root@pam --password ****** --vmid 110 --viewer "C:\Program Files\VirtViewer v9.0-256\bin\remote-viewer.exe" --proxy 43.249.xxx.xxx:55011 --debug

It will result in:

StatusCode:          BadRequest

Could I specify the port for the proxy?

Please add binnary for linux-i386

Let me start by saying I had this working. I was running a VM (ID 106) with an install of Linux Lite and the Display set to SPICE.

I was able to connect to the Spice session from a Raspberry Pi using the command:
cv4pve-pepper --host=192.168.7.5 --username=vm-viewer@pve --password=<redacted> --vmid 106 --viewer-options "-k -f" --viewer /usr/bin/remote-viewer

Today I was having no love for Linux Lite and replaced it with Xubuntu (deleted the VM and created a new one, which got assigned the same ID 106). I have it set with the SPICE display as well and I can access it from my desktop by opening the vv file in Remote Viewer. But the above command on the Raspberry Pi just keeps saying that it cannot find the VM:
Unhandled exception: System.ArgumentException: VM/CT '106' not found! at Corsinvest.ProxmoxVE.Api.Extension.ClientExtension.GetVm(PveClient client, String vmIdOrName) at Corsinvest.ProxmoxVE.Pepper.Program.<>c__DisplayClass0_0.<<Main>b__0>d.MoveNext() --- End of stack trace from previous location ---
I also get the same error if I try to run the above command from my Desktop. So it seems I can launch it with the temporary vv file. but can no longer launch it using cv4pve-pepper.

Once in a while i can getting this error when using your tools

Thanks

On a Raspberry PI 3 running the latest version of Raspberry OS (Buster), and using the ARM version of cv4pve-pepper when I run the following command:

./cv4pve-pepper --host=192.168.1.2 --username=root --password=testPassw0rd --vmid 104 --viewer /usr/bin/virt-viewer

I get the following exception:

Hello,

I'm trying to launch cv4pve-pepper 1.3.7 with ./cv4pve-pepper --host=80.XXX.XXX.XXX:8006 --username=XXXX@XXXX --password=XXXX --vmid=124 --viewer=/usr/bin/virt-viewer and also tried it without specifying the port.
All I get is the following Error:

Error: unknown host 80.XXX.XXX.XXX
Problem connection!

with the --debug flag I get the following:

================ EXCEPTION ================ 
System.ApplicationException

I can open the Web GUI just fine with that URL. What am I missin?

I recently updated my PVE host to 8.2, and cv4pve-pepper was also updated through the Aur on Arch so I'm not sure which was the actual cause but but running my usual command to launch a session results in the below error. Any help or direction is appreciated.

cv4pve-pepper --host=10.10.20.20 --api-token 'root@pam!pveapi=25349687-dcbe-4d8d-b4d5-a6c3e2a4a3f2' --vmid 102 --viewer /usr/bin/remote-viewer

Error: Method 'POST /nodes/pve/qemu/qemu/102/spiceproxy' not implemented'

spiceproxy and pveproxy are both running and starting a spice session via the PVE web admin works without issue.
