[PVE-User] Using Virt-manager with Proxmox

Hi All,
I've proxmox installed on my machine with SME server on KVM as Guest
OS. When I am trying to access the VMs remotely using Virt-manger, I am
getting the below error message:

*010-07-21 11:48:19,463 (error:79): Uncaught Error: Unable to open a
connection to the libvirt management daemon.

Libvirt URI is: qemu+ssh://***@192.168.2.39/system

Verify that:
- The 'libvirtd' daemon has been started


Unable to open connection to hypervisor URI 'qemu+ssh://
***@192.168.2.39/system':
server closed connection
Traceback (most recent call last):
File "/usr/share/virt-manager/* *virtManager/connection.py", line 872, in
_try_open
None], flags)
File "/usr/lib64/python2.6/site-**packages/libvirt.py", line 102, in
openAuth
if ret is None:raise libvirtError('**virConnectOpenAuth() failed')
libvirtError: server closed connection
*
*Maybe you need to install ssh-askpass in order to authenticate.*

Even after installing the ssh-askpass both on the Proxmox server and on the
machine on which virt-manger is running, I am getting the same error. I have
also verified that libvirtd is running on both the machines.

Can some one help me in figuring out what's happening here.

Thank you,

Proxmox VE does not use libvirtd, so this will never work.

I've installed it manually. Will it not work even after installation?

Sir,
Thanks for the reply. Now is there any other way to control the VMs
on proxmox remotely other than the GUI provided by it.

That's great. But may I know if possible, what is that in Promox or

You need to investigate by yourself as I see no benefit for me debugging third party software.

the reason that is preventing me to use libvirt and
Virt-manager.

Simply because proxmox uses it's own tool (qm) to manage
virtual machines, libvirt is not used in any way. If You want to use libvirt
than there is no point in installing proxmox.
