Hi,
Actually, we study virtualization on CentOS with Xen, our goal is to test if the migration of Xen with SLES 11 to CentsOS.
Our first tests are ok except for one problem and I don't find any solutions on the net. I hope, you can help me.
The problem is that I can't connect to my vm desktop with Virt-Viewer. I follow the installation guide available for centos : http://wiki.centos.org/HowTos/Xen/Xen4QuickStart and http://wiki.centos.org/HowTos/Xen/Xen4QuickStart/Xen4Libvirt My CentOS is a fresh new install 6.5 with xen 4.2 and X11.
From Dom0, when I launch virt-manager, everything is ok. I can create a new vm and the first time I connect to the virtual graphics without any problems. But, if I close the desktop VM, I can't access anymore to the virtual desktop of the VM, it is as if the graphics is freazing.The VM is still alive. What is very strange is that I can connect directly with vnc client on 127.0.0.1 :5900 port. I try to launch virt-manager with " --debug " option, but don't find any interesting errors.
I've got the same problem if I remotely launch a virt-manager and connect with xen+ssh from another centos 6.5.
But, I can still connect from a virt-manger launched from a Rh7RC or even from a SLES 11.3.
I think it becomes from virt-manager or libvirt which come with centos 6.5. I made update and I don't know what's wrong with my CentOS 6.5. Don't find any problems like this with Google !
Hmm, I wonder if it's related to this one:
http://marc.info/?l=xen-devel&m=140050749529103
Although since this hasn't even been accepted into upstream libvirt, AFAICT, it's strange that it works with RH7RC and SLES.
Can you tell what port virt-manager is trying to connect to?
