DomU to Dom0 Communication in Xen HVM?
I am new to Xen and want to provide simple communication between my DomU and Dom0 environments. I just need to be able to pass a few bytes of information back and forth between DomU and Dom0 while using some form of event management to know when an update occurs so I can act on it. At first, it appeared that using XenBus and XenStore might be the right solution for this. However, after looking

dom0/domU communication
All, Is there a way to setup serial communication between dom0 and domU. The idea is to have some way of exchanging messages between dom0 and domUs. Certainly, it is possible to use s host-only network, and ssh or shared file system to exchange data. However, there could be cases where the dom0 is not networked. You may want to automate configuring domUs from dom0. Any suggestions. Arijit

iscsitgtd failed request to share on zpool import after upgrade from b104 to b134
Hi, I am posting my question to both storage-discuss and zfs-discuss as I am not quite sure what is causing the messages I am receiving.

During zpool import I am getting a non-zero exit code,

XenStore communication
Hi, I want to know how everything communicates with XenStore. Do domUs use the front-end/back-end driver to dom0 and then the back-end driver contacts xenstored? In particular, how do the xenstore-* commands work on a dom0 and domU? And when should unix-domain sockets be used to communicate with xenstored? Thanks, Hayawardh _______________________________________________ Xen-users mailing

question on xenbus priv in dom0
Hi, In domU, we can''t use xenbus to access anything outside of the domain''s home. That means we are being restricted from reading/writing to other domain''s xenstore. That is perfectly fine, and nobody complains here. But in dom0, do we have the exception? Since dom0 is trusted, I think we can be allowed to access to all other domU''s xenstore. Is that

I want to create a custom directory something like a/b in the xenstore, i guess there are no domU commands for the same. So how can create this in dom0?
