Guests can't connect to each other
Hi,
I'm using libvirt and qemu on Debian Wheezy. I'm having a strange
behavior. Guests can't connect to each other when they're on the same
host.
On the host I'm using bonding (in active / backup mode) and vlan. It
looks like this :
eth0 \ / macvtap0
bond0 --- vlan222
eth1 / \ macvtap1
So I've got two guests, let's say A and B. When

Failing to start or create VM, cannot connect to hypervisor host
Greetings -
I shutdown one of my Centos 6.2 VMs for some offline maintenance and am

to start. I have restarted libvirtd, but did not want to shutdown my

Question about vnc connection password set to empty
Hello, everybody
here I have a question about graphical buffers for rhel7. Thanks so much in advance who can give me some suggestions about that.

VNC ports
I am needing to explicitly assign VNC ports to my virtual guests so that I can connect to them externally via a VNC client, and not virt-viewer. Since I will have multiple KVM Hosts with access to the same shared storage (to facilitate migrations) I need to ensure I have unique VNC ports assigned to each guest so that I don't overlap somehow.
I had planned to use a range of ports starting at

Re: about guest live migration configuration changes persistence ..
Hi,
Thanks for infos.
My concern is the following :
In order to establish datas exchanges between hosts and guest , I'll add a channel device to a running Guest ( as I learned from you that it's possible to do that without stopping the Guest).
When the guest migrates to another host , this one must be able to retrieve the channel device parameters to be able to dialog with the
