Could not refresh total sector count: Resource temporarily unavailable

[HORACIO TORRES GOMEZ]

Hello,

Got QEMU on my ubuntu server.
Also have Xming installed on my windows pc.

I star my VM's this way:
1. From windows, open Xming
2.From windows open a putty session and connect to ubuntu
3. From putty session run $virt-manger
4. Then on my windows PC virt-manager UI shows up an then I can administrate my 
VM's

On QEMU got 3 Windows VM's and 1 linux VM
Everything was working fine until I restarted ubuntu server 3 days ago.

When I start my linux VM works fine.
When I try to star my windows vm's (any of them) I`m receiving error below:

Error starting domain: internal error: process exited while connecting to
